In recent years there have been notable advances in the fisheries. Progresses made in refinements of vessels, new line materials and line-handling systems, preserving the catch, the availability of oceanographic-sensor equipments and the utilization of satellite technology to locate potential fishing grounds have greatly improved the fishing power of longline vessels. Post harvest technology of fish has evolved in the last one decade to a more energy-efficient, cost-effective, and quality upgrading technology. Since fresh fish can get spoiled very quickly, the development of technology for post-harvest preservation and methodology to convert fish to value added products have also become popular in recent times. Value addition helps in getting high price for the fishery products. There is a need to develop competent human resources in the field of post harvest management of fish and production of value added products from them. It is required to inculcate vocational and entrepreneurial skills in order to widen employment opportunities, particularly among rural youth and the disadvantaged sections of the society as well as to enable self employment.

The characteristics of Northern squawfish (Ptychocheilus oregonensis) and the feasibility of utilization of this species for human consumption were investigated. In the first experimental phase, the iced storage characteristics of squawfish were determined. Quality changes were monitored over 24 days of storage by chemical, physical, microbiological and sensorial methods of analysis. The Torrymeter readings, K value, descriptive sensory evaluation and taste panel tests demonstrated that squawfish kept well in ice for 15 days. The torsion test results showed that squawfish exhibited good gel forming ability and decreased only 15% of the original value after 24 days of iced storage. The K value might provide the basis of a raw material quality control system for processing. Production of deboned fish mince could be an effective method for utilization of bony squawfish. In the second experimental phase, quality of minced flesh from squawfish was investigated. Texture properties of minced gels as determined by torsional shear stress and strain, at fracture, showed that there was no significant difference in strain value between unwashed and washed mince. No significant differences were also found in strain values of minced gels due to different temperature settings. The addition of cryoprotectants was very effective in maintaining strain value for both unwashed and washed mince during three months of frozen storage. Thiobarbituric acid (TBA) analyses showed minced flesh maintained good quality with regard to oxidation. In the third experimental phase, the suitability of squawfish (Ptychocheilus oregonensis) as a potential species for surimi processing was investigated on the basis of post harvest freshness. The yield of surimi from whole fish ranged between 15.5-21.6%. Fish freshness had a positive correlation with initial surimi quality. The quality changes of surimi during frozen storage depended upon the freshness of material and were influenced by the duration of storage. One wash cycle improved the color of surimi gel significantly. However, there were no significant differences in strain values measured by torsion test due to different wash cycles. Results of the experiment indicated that it was feasible to produce surimi from squawfish stored on ice for up to 9 days. One wash-cycle was adequate for squawfish surimi production.
