Abstract:
The present scenario of industrial fishing in India is that most of large trawlers are based at Visakhapatnam and congregate in the potential shrimp ground in the
upper East coast of India commonly known as the Sandheads. These are outriggcr vessels operating two or four trawl nets along with a testing trawl called try
net. In the early Seventies these vessels were operating on a very high economic return which was evident from the steady increase in number of outriggers over a period of twenty years. Since the total allowable catch has to be
shared by all vessels including the increasing fleet, reduction per vessel output is bound to happen. Therefore some of them could not survive the competition
and withdrew from the scene. The number of outriggers did not increase subsequently. However, there arose a doubt whether the existing fleet of about 180 vessels are fishing economically or whether there is any scope for further introduction of industrial vessels in the region. This study is focussing to the techno economic aspects of industrial fishing in the upper East coast of India

Abstract:
In the present study an attempt has been made to understand the microzooplankton community along the easr coast of India. Most of the earlier studies projected Bay of Bengal as an oligotrophic system where phytoplankton growth is limited by a number of factors among which nutrients are the foremost. Hence it is logical to consider that the most of the primary production in the Bay of Bengal could be contributed by small sized phytoplankton harnessing the available resources, which in turn can be utilized effiency by the microzooplankton only. Hence microzooplankton could play in transferring primary organic carbon to higher tropic levels in this region.

Abstract:
The great number of parasitic species of marine
and brackishwater animals that have been described indicates
that parasites play an important part in the ecology
of the oceans and brackishwaters. Jnspite of their
importance, marine and brackish parasites are
probably the least known group of organisms. Considering
the large number of marine and brackishwater hosts, especially in the tropics, it is no exaggeration to say
that the description of marine and brackishwater parasites
has hardly begun (Rohde, 1982). With this view in mind,
an attempt has been made to study the ecobiology of the
helminth parasites of finfishes and shellfishes of eochin
waters with special reference to digenetic trematodes.
The work is broadly divided into three chapters,
Chapter 1 consists of a description of the study area,
prevalence of infection and concurrent infections with
helminth parasites, seasonal variation, host specificity>
and zoogeography of digenetic trematodes; Chapter II
deals with the systematics of digenetic trematodes; and
Chapter III deals with studies on larval trematodes from
molluscs and crustacea, adult from a molluscan host,
life-cycle, biology and histopathology

Abstract:
The main objectives of the present investigation were to evaluate the qualitative and quantitative distribution of natural cyanobacterial population and their ecobiological properties along the Cochin estuary and their application in aquaculture systems as a nutritional supplement due to their nutrient-rich biochemical composition and antioxidant potential. This thesis presents a detailed account of the distribution of cyanobacteria in Cochin estuary, an assessment of physico-chemical parameters and the nutrients of the study site, an evaluation of the effect of physico-chemical parameters on cyanobacterial distribution and abundance, isolation, identification and culturing of cyanobacteria, the biochemical composition an productivity of cyanobacteria, and an evaluation of the potential of the selected cyanobacteria as antioxidants against ethanol induced lipid peroxidation. The pH, salinity and nutritional requirements were optimized for low-cost production of the selected cyanobacterial strains. The present study provides an insight into the distribution, abundance, diversity and ecology of cyanobacteria of Cochin estuary. From the results, it is evident that the ecological conditions of Cochin estuary support a rich cyanobacterial growth.

Abstract:
Prawn culture by traditional method forms an important occupation for the people in these areas, especially in the Vypeen island. Though short term studies have been made on various aspects of prawn culture field and its ecology, a study of detailed nature covering perennial, seasonal, fields and canals between coconut plantation is lacking from these areas. This study will also enable to assess the relative productivity of different systems during different seasons and the influence of the environment on the production potentials. Therefore the present study is taken upto throw more light on the ecological characteristics of these fields with special emphasis on its primary, secondary and tertiary production. The present area of investigation includes the prawn culture fields adjacent to Cochin backwater. The Cochin backwater (O9° 58'N 76° 28'E) is a shallow semi-enclosed body of water of tropical estuary. A narrow gut, about 450 M wide forms its main connection with the Arabian sea and this region is subjected to regular tidal influenceertiary production.

Abstract:
This thesis entitled ecology of chaetognaths in the indian EEZ.The present study, in general, deals with the distribution pattern of mesozooplankton biomass and abundance with special reference to the detailed ecology of the important carnivorous planktonic group, the chaetognath, in the two major ocean basins of the Indian EEZ, the Arabian Sea (AS) and the Bay of Bengal (BoB). Prior to the International Indian Ocean expedition (IIOE, 1960 – 1965), cmprehensive studies on chaetognath in the Indian waters were very limited and was confined mostly to some coastal and oceanic regions.
The study revealed a profound influence of different physical process on the abundance of chaetognath community. The significant influence exerted by different physico-chemical factors on the vertical distribution of chaetognath species was also evident.
Prior to this study, only very little information was available on the ecology and distribution pattern chaetognaths in both the Arabian sea and the Bay of Bengal in relation to various mesoscale processes and physicochemical .variables. This study, emphasizing the short term and long term influences of different meso-scale and basin scale physical events on the ecology of this important plankton group provides the baseline data for extensive ecological research on any major mesozooplankton group in this tropical low latitude region.

Abstract:
A massive programme for the development of small scale industries in India known as ‘Industrial Estates Programme‘ was launched by the Government of India in 1955, This technique of industrialisation was recommended by the Small Scale Industries Board in 1955.
The first industrial estate in India was set up at Rajkot (Gujarat) in September 1955 and the first shed allotted in December 1955. Since the Government of India entrusted the state governments with the responsibility of starting the estates, the Government of Kerala decided to start one industrial estate in each district during the second plan. It was envisaged that each district should have two industrial estates each, one as urban estate, the other as semi-urban or rural estate. This study attempts to make an economic evaluation of the Industrial estates programme in Kerala. It is based on a survey of all working industrial units in the 17 major industrial estates of Kerala.

Abstract:
Comprehensive studies integrating production, consumption and
marketing of ornamental fishes were never conducted in the past in
Kerala and this study is an attempt to highlight the dynamics in a
systematic manner by making a primary empirical study. The
advantages of such an approach are many. First, the study entails
detailed empirical data under a given time frame on various inter linked
economic activities in ornamental fisheries sector. Second, the study
tries to improve upon the previous discipline-bound studies by adopting
an integrated approach. As Kerala has diverse ecological and climatic
conditions, case studies on various ornamental fish production
systems help identifying suitable culture practice for selected
environmental conditions. One of the major conclusions of this study
as explained in the concluding chapter is that although Kerala is
blessed with favourable geographic and climatic conditions needed for
developing ornamental fishery, diverse local conditions and
requirements contain adopting modern methods of enterprise
development.Consumer studies conducted would help to identify the demand of
ornamental fishes and the factors leading to it. Market studies would
help in understanding the forces behind domestic market, which is very
promising, but neglected. Viability studies throw light on the economic
performance of both the production systems and the trading units of
ornamental fishes. Despite the economic significance of ornamental
fisheries industry, its development has been constrained due to various
bio-technical, cultural, socio-economic, organisational and above all,
institutional and policy failures. The outcome of the study would identify
constraints facing the industry and institutional arrangements for
development.

The importance of industrialisation in achiering rapid
economic growth has been recognised in India's development
strategy ever since the inception of economic planning in the
country. Being the secondary sector in the generation of national
income. industry contributes significantly to the process
of economic development. Extensive debates have taken place on
the nature of the industrialisation strategy to be pursued in
the economy since Independence. This is reflected in the
industrial policy which evolved through the various five year
plans and policy resolutions. Stupendous efforts have been
made by the government since the commencement of planning and
particularly since the 1960s to industrialise the Indian economy
and develop the infrastructural base for sustained industrial
development. It is difficult to assess the performance of the
industrial sector over the past three decades with respect to
the broad objectives of industrialisation. However. there are
certain areas in which the achievements have been clearly
significant.

Abstract:
The major objective of this chapter was to estimate the indirect benefits provided by the Cochin wetlands to direct, indirect and non-user populations.This chapter gives the details of the Contingent valuation survey that was executed in the study area. Section one described the actual survey and its execution. Section two undertook a detailed discussion of the methodological issues involved in the survey. Section three contained some discussion on the study.This analysis has demonstrated the feasibility of extending the use of contingent valuation methods to local populations in developing countries like India. Certain issues emerge from these applications. Income is strongly
related to willingness to pay in these surveys, yet income levels are often low.Secondly, education is not a factor that influences willingness to pay in the coastal belt very much. Rather, relation of individual occupation to any wetland based activity very much influenced their willingness to pay. The study revealed that people very much valued the indirect function performed by wetlands, in fact as much as they valued the direct benefits provided by the system. There still exist differences of opinions among experts when undertaking such valuation studies. However, in the absence of a better
technique for valuing environmental services that have no markets, this is definitely a first step

The world demand for fish and fishery products is increasing steadily and it is
generally accepted that it will not be possible to meet the heavy demand with resources
exploited from capture fishery alone. Now aquaculture is well established and fastdeveloping
industry in many countries and is a major focus sector for development.
During recent decades, aquaculture has gained momentum, throughout the world
especially in developing countries. According to Food and Agricultural Oganisation
(FAO, 2000), global aquaculture production was 26.38 tones in 1996 have reached
32.9 million tonnes during 1999. Only marine aquaculture sector has contributed 13.1
million tonnes during 1999.India is a major fish producing country. About one half of lndia’s brackish
water lands are currently being utilized for farming in order to reduce the gap between
supply and demand for fish. Aquaculture has become a major source of livelihood for
people and its role in integrated rural development, generation of employment and
earning foreign exchange, thereby alleviating poverty is being greatly appreciated
around the world.Among the infectious agents, bacteria are becoming the prime causal
organisms for diseases in food fishes and other marine animals. Sindermann, (1970)
reported that bacterial fish pathogen most commonly found among marine fishes is
species of Pseudomonas, Vibrio and Mycobacterium. These can be categorized into
primary pathogens; secondary invaders that may cause systemic disease in
immunocompromised hosts; and normal marine flora which are not pathogenic but
may occur on body surfaces or even within the tissues of the host. I-Iigh density of
animals in hatchery tanks and ponds is conducive to the spread of pathogen and the
aquatic environment with regular application of protein rich feed, is ideal for culturing
bacteria. Bacteria, which are normally present in seawater or on the surface of fish, can
invade and cause pathological effects in fishes, which are injured or subjected to other
environmental stresses.Mycobacteria except parasites are known as nontuberculosis mycobacteria
(NTM), atypical mycobacteria or mycobacteria other than tuberculosis(MO'l'l"). This
group of mycobacteria includes opportunistic pathogens and saprophytes.
Environmental mycobacteria are ubiquitous in distribution and the sources may
include soil, water, warm-blooded as well as cold-blooded animals. Disease caused by
environmental mycobacterial strains in susceptible humans (Goslee & Wolinsky,
1976; Grange, 1987), animals and fishes are increasingly attracting attention. Greatest
importance of environmental mycobacteria is believed to be their role in
immunological priming of humans and animals, thereby modifying their immune
responses to subsequent exposure to pathogenic species.

Abstract:
The heavy metal contamination in the environment may lead to
circumstances like bioaccumulation and inturn biomagnification. Hence
cheaper and effective technologies are needed to protect the precious
natural resources and biological lives. A suitable technique is the one
which meets the technical and environmental criteria for dealing with a
particular remediation problem and should be site-specific due to spatial
and climatic variations and it may not economically feasible everywhere.
The search for newer technologies for the environmental therapy, involving
the removal of toxic metals from wastewaters has directed attention to
adsorption, based on metal binding capacities of various adsorbent materials.
Therefore, the present study aim to identify and evaluate the most current
mathematical formulations describing sorption processes. Although vast
amount of research has been carried out in the area of metal removal by
adsorption process using activated carbon few specific research data are
available in different scientific institutions. The present work highlights the
seasonal and spatial variations in the distribution of some selected heavy
metals among various geochemical phases of Cochin Estuarine system and
also looked into an environmental theraptic/remedial approach by
adsorption technique using activated charcoal and chitosan, to reduce and
thereby controlling metallic pollution.
The thesis has been addressed in seven chapters with further
subdivisions. The first chapter is introductory, stating the necessity of
reducing or preventing water pollution due to the hazardous impact on
environment and health of living organisms and drawing it from a careful
review of literature relevant to the present study. It provides a constricted
description about the study area, geology, and general hydrology and also
bears the major objectives and scope of the present study.

Abstract:
The pollutants discharged into the estuaries are originate from two
main sources-industrial and sewage. The former may be toxic which
includes heavy metals, residues from antifouling paint particles and
pesticides, while large discharges of sewage will contain pathogenic microorganisms.
The contamination is enough to destroy the amenities of the
waterfront, and the toxic substances may completely destroy the marine life
and damage to birds, fishes and other marine organisms. Antifouling
biocides are a type of chemical used in marine structure to prevent
biofouling. These antifouling biocides gradually leach from the ships and
other marine structures into water and finally settled in sediments. Once a
saturation adsorption is reached they desorbed into overlying water and
causes threat to marine organisms. Previous reports explained the imposex
and shell thickening in bivalves owing to the effect of biocides. So bivalves are used as indicator organisms to understand the status of pollution. The
nervous system is one of the best body part to understand the effect of
toxicant. Acetylcholine esterase enzyme which is the main neurotransmitter
in nervous was used to understand the effect of pollutants. Present study
uses Acetylcholine esterase enzyme as pollution monitoring indicator

Abstract:
Starve feeding of single screw extruder was described as an
important means of improving the performance characteristics of the
extruder. In addition to such improvement with versatility, the starve
feeding technique also may affect the mechanical properties of the
extrudate since the heat transfer an(l mixing characteristics in the starve
fed and Hood fed extruders are not the same. Since the material is more
loosely packed in the channels of the starve fed extruder, there may be
greater bed mobility and uniformity. Further, the. thermal an(l shear
induced degradation are also less since possibilities of developing local
high temperatures are less compared to a densely compacted extruder
bed. This study has been undertaken mainly to explore the effect of
feeding rate on the mechanical properties of rubber and plastic extrudates
since the effect of feeding rate has not been analysed from this angle so
far.

Organic-inorganic nanocomposites combine unique properties of
both the constituents in one material. Among this group of materials,
clay based as well as ZnO, TiO2 nanocomposites have been found to
have diverse applications. Optoelectronic devices require polymerinorganic
systems to meet certain desired properties. Dielectric
properties of conventional polymers like poly(ethylene-co-vinyl acetate)
(EVA) and polystyrene (PS) may also be tailor tuned with the
incorporation of inorganic fillers in very small amounts. Electrical
conductivity and surface resistivity of polymer matrices are found to
improve with inorganic nanofillers. II-VI semiconductors and their nano
materials have attracted material scientists because of their unique
optical properties of photoluminescence, UV photodetection and light
induced conductivity. Cadmium selenide (CdSe), zinc selenide (ZnSe)
and zinc oxide (ZnO) are some of the most promising members of the IIVI
semiconductor family, used in light-emitting diodes, nanosensors,
non-linear optical (NLO) absorption etc. EVA and PS materials were
selected as the matrices in the present study because they are
commercially used polymers and have not been the subject of research
for opto-electronic properties with semiconductor nanomaterials

Abstract:
In the present scenario of energy demand overtaking energy supply top priority is given
for energy conservation programs and policies. Most of the process plants are operated
on continuous basis and consumes large quantities of energy. Efficient management of
process system can lead to energy savings, improved process efficiency, lesser operating
and maintenance cost, and greater environmental safety. Reliability and maintainability
of the system are usually considered at the design stage and is dependent on the system
configuration. However, with the growing need for energy conservation, most of the
existing process systems are either modified or are in a state of modification with a view
for improving energy efficiency. Often these modifications result in a change in system
configuration there by affecting the system reliability. It is important that system
modifications for improving energy efficiency should not be at the cost of reliability. Any
new proposal for improving the energy efficiency of the process or equipments should
prove itself to be economically feasible for gaining acceptance for implementation. In
order to arrive at the economic feasibility of the new proposal, the general trend is to
compare the benefits that can be derived over the lifetime as well as the operating and
maintenance costs with the investment to be made. Quite often it happens that the
reliability aspects (or loss due to unavailability) are not taken into consideration. Plant
availability is a critical factor for the economic performance evaluation of any process
plant.The focus of the present work is to study the effect of system modification for improving
energy efficiency on system reliability. A generalized model for the valuation of process
system incorporating reliability is developed, which is used as a tool for the analysis. It
can provide an awareness of the potential performance improvements of the process
system and can be used to arrive at the change in process system value resulting from
system modification. The model also arrives at the pay back of the modified system by
taking reliability aspects also into consideration. It is also used to study the effect of
various operating parameters on system value. The concept of breakeven availability is
introduced and an algorithm for allocation of component reliabilities of the modified
process system based on the breakeven system availability is also developed. The model
was applied to various industrial situations.

molluscan and demersal fisheries. Also it formed the dumping area for sewage,235
retting of husks and discharge of effluents from industries located on either side
of it. As a result the fishery is being gradually dwindled year after year due to
the lowering of the water quality. The effect of industrial polution on the benthic
community of this tropical estuary was worked out. An area extending over 21
km from the mouth of the estuary to upstream of industrial belt was selected.
Temporal and spatial variations of 16 environmental parameters at 9 stations
along the area were monitored monthly during 1981. Benthic fauna of these 9
stations consisted of amphipods , polychaetes, isopods, tanaidaceans, molluscs
and other crustaceans (Decapods, Acetes, Alpheids, Balanus, insect larvae,
chironomid larvae, cumacea and some fresh water forms ). Apart from these, sea
anemone, flat worms, nematodes, sipunculoids, echinoderms and fishes were
also encountered. 75 species belonging to 31 faunal groups were identified. Of
these 31 groups, amphipods, polychaedes, isopods, tanaidaceans and molluscs
were numerically abundant. Rest of the 26 groups (including 13 riverine forms)
were found less significant due to their rare occurrence/low numerical abundance.
Polychaetes and molluscs were the only major groups present at all the stations.
