Abstract:
Cephalopods are utilized as an important food item in various countries because of its delicacy as raw consumed food. Mainly sepia and loligo are consumed raw by Japanese and Russians. The freshness of the products is very important when the product is consumed raw. The major species that dominate our squid catch are Loligo duvaucelii and Doryteuthis sibogae. There is a noticeable difference in the quality of both the species. The needle squid (Doryteuthis sibogae ) contributes about 35% of the total squid landing. Due to the fast deterioration , a major portion of the needle squid, which is caught during the first few hauls, is thrown back to sea. The catch in the last hauls only are taken to the landing centers. At present the needle squid is processed as blanched rings and the desired quality is not obtained if it is processed as whole, whole cleaned or as tubes. In this study an attempt is made to investigate the biochemical characteristics in both the species of squid in relation to their quality and, the process control measures to be adopted. The effect of various treatments on their quality and the changes in proteolytic and lysosomal enzymes under various processing conditions are also studied in detail.Thus this study can provide the seafood industry with relevant suggestions and solutions for effective utilization of both the species of squid with emphasis on needle squid.

Abstract:
In the present study two aspects of cephalopod fishery such as (i)
landings and (ii) utilization including export of cephalopods from Indian are
dealt with. Under the topic landings, craft, both traditional and mechanized
and fishing techniques employed for capturing cephalopods are discussed.
General trend in cephalopod landing in India and particularly south west coast,
species composition, description and geographic distribution of important
species of cuttle fishes, squids and octopus and the distribution and abundance
of cephalopods along the continental shelf of the south west coast are also
discussed. Some biological aspects like population parameters, maturation and
spawning, food and feeding of the two representive species of cuttle fishes and
squid viz, Sepia pharaonis and Loligo duvauceli are studied.Under utilization, general handling and processing of various frozen
cephalopods products for exports and commercial operation in a typical plant
are studied. The export of cephalopod products since its commencement is
studied in detail and market strategy for enhancing the export are suggested.
