Conservation studies in fisheries is multi disciplinary and it needs support of various experts to address the issues. Several issues in conservation and management of hilsa fisheries require both ecological and societal issues. However, the conservation of hilsa in West Bengal is a major issue for remarkable decline of its production because of anthropogenic activities. The present investigation of awareness level of fishers through a pretested questionnaire was administered to fisher population in three localities, such as, Diamond Harbour, Kakdwip and Godakhali during the period of investigation from June, 2013 to December, 2013. It contained 35 items on different aspects of hilsa fisheries, such as, the status and need of education on different aspects. It was administered before and after suitable interventions which included individual contacts, mass contacts, local news papers, posters and leaflets. The present study revealed that 76% population were of a view that hilsa catch is not at equilibrium and it is declining which needs protection (86%). It was attributed to unregulated fishing (78%), environmental factors (90%), fisheries for livelihood (98%) and anthropogenic pressure (76%). There was a significant difference (P<0.05) in awareness level on different items due to various type of interventions.- Length-Weight Relationship and Condition Factor of Mrigal Cirrhinus mrigala (Hamilton) Reared in Bheries of 24-South Paraganas District in West Bengal

An attempt was made to study length-weight relationship and condition factor of Indian major carp, mrigal (Cirrhinus mrigala) reared in bheries at Bhamanghata of 24-South Parganas district in West Bengal. Samples of 323 fishes having size range of 127 mm to 334 mm were taken to estimate length-weight relationship. The regression equation was found as logW = -4.239 + 2.753 logL (r = 0.885) for male, logW = -4.388 + 2.823 logL (r = 0.871) for female and logW = -4.372 + 2.797 logL (r = 0.876) for pooled sample and it exhibited significant correlation (P<0.05) between length and weight. It was found that the exponent 'b' value varied significantly from '3' indicating allometric growth. The mean relative condition factor (Kn) was found to vary from 0.94 to 1.14 during the period of investigation. It varied significantly (F11, 11= 3.37, P<0.05) during different months which were attributed to food and feeding habit of fish. The variations in exponent and dynamics of relative condition factor of fish are discussed referring earlier works.- Length-Weight Relationship and Relative Condition Factor of Mrigal Cirrhinus mrigala (Hamilton) Reared in Bheries of 24-South Parganas District in West Bengal

Nutritional characteristics of fish flesh, such as, proximate composition and organoleptic characteristics of fish grown in Eichhornia and Colocasia leaf powder diets as well as fishmeal based control diet were evaluated after 8 weeks of laboratory experiment. Significant difference (P < 0.05) was observed in crude protein and crude fat levels in fish flesh. Moisture and lipid level were inversely related. Organoleptic evaluation indicated significant difference (P < 0.05) in overall quality of flesh in raw fish in different treatments whereas it was not significant in cooked fish. There was no significant difference in overall quality of fish flesh in treatments having 20% and 30% level of incorporation of leaf powder in pellet feed.Keywords

Fisheries sector plays an important role in agrarian economy and nutritional security of India. There exists ample opportunity to enhance fish production adopting different scientific approaches. Development of knowledge and skill of fishery professionals is the key to meet the demand in national and international level. It can be well addressed by developing creativity amongest under graduate students in discipline of Fishery Science. Meta learning and conducive environment induce creativity. Important components of creativity are person, process, product and press (environment). Its assessment procedures and five levels in scientific model of creativity are discussed. Need of development of creativity in students in discipline of Fishery Science in present day context is narrated.Keywords

Three test diets were prepared by partial replacement of fish meal with leaf powders of Eichhomia crassipes (Diet E), Colocasia escnlenta (Diet C) and Gliricidia maailata (Diet E). Test diets along with fish meal based control diet (Diet FM) were evaluated for their impacts on total tlsh production and organoleptic characteristics in two test species, viz., Catla catia and Labeo rohita after a period of culture of 112 days. Catia showed relatively higher production in fish meal based diet whereas rohu registered more production in leaf protein based diets. No significant difference existed in organoleptic characteristics of carps among treatments. However, the difference was significant (P < 0.05) between attributes except raw fish of lohu.Keywords

Feeding intensity and food spectrum of Labeo rohiia (Hamilton) were monitored along with water characteristics in Kulia bee! of West Bengal during premonsoon and postmonsoon seasons. Gastrosomatic Index and percentage of actively fed fish were significantly more during postmonsoon period. Diet composition during two sea.sons exhibited distinct variations. Such seasonal dynamics in feeding intensity and foraging was attributed to abundance of plankton and spawning of fish.Keywords
