Opportunity inequality and its relationship with economic growth is a concept to which not enough attention has been paid in the previous studies. This study attempts to investigate the effects of opportunity inequality index on economic growth in 15 developing and 15 developed countries over the years 1995-2015. Accordingly, the mean group (MG) estimator within the framework of panel data was ...

From July, 1999 until July, 2001 data from the pink-shrimp Farfantepenaeus brasiliensis Latreille, 1970 and F. paulensis Pérez-Farfante, 1967 fishery were collected from trawling by the fishing fleet based in Santos/Guarujá-SP. Growth and mortalities of these species were studied. F. brasiliensis and F. paulensis have longevity of 2 years and growth estimates of L Infinity = 29.0 cm and k = 1.2...

the purpose of this research was to study the effects of four personal and social variables including the age, literacy, job experience and size of herd on different variables such as implementing of managerial strategies in transition period, relevant costs of these strategies, average production per head and gross income of milk sale per head. for this purpose all required information were co...

Perhaps the most fundamental insight from fishery science is that ecosystems impose important and predictable constraints on food production from the sea. The familiar hump-shaped growth curve implies that the growth rate and carrying capacity of a species limit its production: Once stocks are depleted, further increasing fishing pressure will only lead to decreases in catch. This logic underpi...

The objective of this paper was to study angling from September, 2002 to September, 2004 in the Lobo-Broa Reservoir, Itirapina, SP (22 degrees 15' S and 47 degrees 49' W). Interviews (total 1,027) with sport fishers were accomplished in the three main fishing sites (Horto, Píer and Praia). This fishing was practiced with a simple fishing rod and reel, mainly in Horto, where the catches and fish...

The queen conch Strombus gigas represents one of the most important fishery resources of the Caribbean but heavy fishing pressure has led to the depletion of stocks throughout the region, causing the inclusion of this species into CITES Appendix II and IUCN's Red-List. In Mexico, the queen conch is managed through a minimum fishing size of 200 mm shell length and a fishing quota which usually r...
