Abstract:
Fish and fishery products are having a unique place in global food
market due to its unique taste and flavour; moreover, the presence of easily
digestible proteins, lipids, vitamins and minerals make it a highly demanded
food commodity.Fishery products constitute a
major portion of international trade, which is a valuable source of foreign
exchange to many developing countries.Several new technologies are emerging to produce various value
added products from food; “extrusion technology” is one among them.
Food extruder is a better choice for producing a wide variety of high value
products at low volume because of its versatility. Extruded products are
shelf-stable at ambient temperature. Extrusion cooking is used in the
manufacture of food products such as ready-to-eat breakfast cereals,
expanded snacks, pasta, fat-bread, soup and drink bases. The raw materialin the form of powder at ambient temperature is fed into extruder at a known
feeding rate. The material first gets compacted and then softens and
gelatinizes and/or melts to form a plasticized material, which flows
downstream into extruder channel and the final quality of the end products
depends on the characteristics of starch in the cereals and protein ingredient
as affected by extrusion process. The advantages of extrusion process are
the process is thermodynamically most efficient, high temperature short
time enables destruction of bacteria and anti-nutritional factors, one step
cooking process thereby minimizing wastage and destruction of fat
hydrolyzing enzymes during extrusion process and enzymes associated with
rancidity.

Abstract:
This study mainly deals with the structure of the motorised and mechanised trawl fishing fleet of Kerala, and assess the availability of resources and its extent of exploitation. The study is conducted by observing the performance of small motorised boats operating trawl nets from selected centers along the Kerala coast. The Study also deals with the type and material of construction of the propellers used in selected crafts and the efficiency of the propeller. The fuel consumption pattern of selected medium sized trawlers economics of operation of selected fishing crafts are analyzed through this study. The thesis also Suggest methods for reducing fuel consumption in trawling

Abstract:
Despite various intervensions, artisanal fishermen remain one of the weaker sections in Kerala's society. Host of the welfare and developmental programmes introduced for them had produced very little impact on their living conditions. Further, they are unable to compete with mechanised sector for fishing. Host of the technological development which had taken place after Indo-Norvegean Project favoured the growth of mechanised sector. As a consequence of this, fishing become unviable for artisanal fishermen who propagate the idea of ” sustainable development” in the fishing industry. It is commonly believed that an integrated approach may help them to
improve their living conditions substantially. In the light of the above background the scholar has made an attempt to study the impact of Integrated Marine Fisheries Development Project among artisanal fishermen in Kerala It is realised from the findings of the study that the most important needs of artisanal fishermen arecredit facilities and marketing support. Without marketing linkages effective credit management is not possible. Marketing activities and credit management are interdependent
