The fishery and resource characteristics of pomfrets

Pomfrets contribute to about 2% in all India fish catch. They are abundant along the coasts of Maharashtra, Gujarat and Orissa. Pampus argenteus forms 65.9%, Formio niger 33.2% and Pampus chinensis 0.9% of the catch. They feed on planktonic organisms like salps, medusae and ctenophores. Both P. argenteus and F. niger have prolonged spawning with two peaks. The breeding ground of P. argenteus is the depth realm 55-90 m offCambay and Sand head; while the inshore areas of Bombay, Cambay and Sand head appear to be the nursery grounds. They are pelagic and are caught mainly in driftnet, trawl net and dolnet. The estimated MSYfor P. argenteus for Indian waters is 38,194 t while for F. niger is 20,446t. The fishery of P. argenteus has collapsed in Maharashtra due to growth and recruitment overfishing

Fishery, biology and resource characteristics of golden anchovy, Coilia dussumieri (Cuv & Val)

Coilia dussumieri (Cuv & Val) forms an important component of dol net fishery. Maharashtra and Gujarat contribute 10022 t and 14745 t respectively, while West Bengal and Orissa land 4000t and 586 t respectively. The species is a pelagic zooplanktonjeeder, feeding mainly on copepods, ostracods. sergestes and young ones offish. It spawns once in life during April-June. Size at first maturity has been estimated as 162 mm for females and 160 mm for males. The growtli parameters estimated are Loo = 230 mm and K = 1.35. The total mortality coefficient (Z) is 5.468 and MSY 16395 t, whereas the average yield is 8509 t indicating that the fishing is below optimum level and it can sustain increased effort up to 126%

Fishery resource characteristics and stock assessment of ribbonfish, Trichiurus lepturus (Linnaeus)

Ribbonfish, Trichiurus lepturus (Linnaeus) has become one of the most important exploited resources in the northwest coast of India. It was landed as bycatch of shrimp trawler earlier but on account of emerging export demand it is now increasingly targeted. The resource has been monitored for more than ten years. The landings of ribbonfishes varied between 16,000 t (1995) and 63,000 t (2000) with an average catch of 33,000 t. The trawl contributed about 93 % of the total landing. Peak catch rates were observed in September and November-December. T. lepturus is a carnivorous predator feeding on crustaceans, fishes and cephalopods. Spawning season is prolonged from October-May. Individual fish spawns once in a year and the minimum size at maturity is 75 cm. The fecundity varied between 4,900 and 81,000 with a relative fecundity of 65 ova/gm of body weight

Evaluating Competition Strategies for Generic Drug Industries Using Game Theory - A supplement to report “Scenario Planning as a Tool for Long Term Strategic Planning”

This report is a supplement to the project titled “Scenario Planning as a Tool for Long Term Strategic Planning - The Generics Drug Industry in the European Union.” The report will further evaluate the resultant scenarios and strategies build and recommended as part of the titled project mentioned above. Game theory perspectives will be used as a tool to analyse how economic agents (stakeholders of the pharmaceutical generic drugs industry) will react when what they do affects the actions of others. The report will evaluate hypothetical actions taken by generic drugs industry players and their outcomes/payoffs relative to the competitions. It will draw on strategic and extensive forms of games to identify how to act and how to think about your rival’s actions. What would be a more powerful in business strategy than this

Dol net fishery off Nawabunder (Gujarat)

The 'dol' net is' one of the most important gear used in strong tidal current along the coasts of Maharashtra and Gujarat. The Bombay duck, Harpodon nehereus (Ham) is the main constituent of the catch so much that the 'dol' net fishery has become synonymous with Bombay duck fishery. However, a detailed catch composition revealed that Bombay duck forms 68.6-77% of the total 'dol' net landings along the Saurashtra coas
