Abstract:
Crustaceans comprising numerous edible species of prawns, lobsters and crabs inhabiting different ecosystem form significant portion of the aquatic food resources of the world. Among the crustaceans, prawns are the most commercially exploited group and hold premier rank by virtue of their importance as an esteemed food of gourmet and on account of their high export value. Met-ape-naeus manoceras (Fabricius, 1798) which is known IS,Speckled shrimp’ (FAD name) and ‘Brown shrimp’ ( common nameused in the industry) is one of the commercially important marine penaeid prawns of India. During 1995, M. monaceros catch constituted 7.5 Z of the all India marine penaeid prawn landings. M. monoceros attains a maximum length of about 200 mm and has high export potential.Thus realising the growing importance of M. monoceros in the capture fisheries, it was felt, that it would be ideal to carry out detailed study on this species for rational exploitation and management of its fishery. Hence, the present work entitled, “Biology, population characteristics and fishery of the speckled shrimp Hetapenaeus monoceros (Fabricius, 1798) along Kerala coast“ was undertaken by the author. The thesis is laid out in seven chapters comprising TAXONOMY, FOOD AND FEEDING HABITS, AGE AND GROWTH, REPRODUCTION,LENGTH-WEIGHT RELATIONSHIP, FISHERY and POPULATION DYNAMICS

Abstract:
The present study was undertaken with a view to understanding some aspects of the morphology, bionomics and physiology of the sea anemone A.nigrescens. This species was selected for the study since it is abundantly available along the coast throughout the year and can successfully reared in the laboratory without much effort. The present study deals with the following aspects of A.nigrescens. description of the species, habitat, food and feeding, digestion, studies on salinity tolerance, studies on oxygen consumption, studies on tolerance to desiccation, asexual reproduction and regeneration.

Abstract:
Extensive investigations on the distribution and
biology of skipjack tuna are available but less is known of the
bait fishes on which this fishery depends and what is known is
inadequate, fragmentary and of cursory nature. The information
available on tuna livebait fishes of Lakshadweep are mainly
cofined to short term surverys aimed at estimating theiravailability and abundance. Reports on the biology of a few
species from Minicoy are also present in the literature. This
study was, therefore, prompted by a paucity of information on
1) the livebits of Minicoy, 2) livebait fishery of the northern
islands and 3) knowledge of livebait ecology
