Adaptive responses of tropical tuna purse-seiners under temporal regulations ArchiMer
Torres-irineo, Edgar; Dreyfus-leon, Michel; Gaertner, Daniel; Salas, Silvia; Marchal, Paul.
The failure to achieve fisheries management objectives has been broadly discussed in international meetings. Measuring the effects of fishery regulations is difficult due to the lack of detailed information. The yellowfin tuna fishery in the eastern Pacific Ocean offers an opportunity to evaluate the fishers’ responses to temporal regulations. We used data from observers on-board Mexican purse-seine fleet, which is the main fleet fishing on dolphin-associated tuna schools. In 2002, the Inter-American Tropical Tuna Commission implemented a closed season to reduce fishing effort for this fishery. For the period 1992–2008, we analysed three fishery indicators using generalized estimating equations to evaluate the fishers’ response to the closure. We found...

Growth, longevity, and juvenile recruitment of the white shrimp Litopenaeus schmitti (Burkenroad, 1936) (Decapoda: Penaeoidea) in southeastern Brazil Biological Sciences
Miazaki, Lizandra Fernandes; Santos, Ana Paula Freitas dos; Salvati, Dalilla da Silva; Simões, Sabrina Morilhas; Costa, Rogério Caetano da.
 Litopenaeus schmitti is one of the most commercially exploited penaeids on the southeastern and southern Atlantic coast of Brazil. Information about juvenile recruitment and growth patterns of individuals is important for management programs. The present study estimated the growth parameters, longevity, and recruitment of L. schmitti in the region of Ubatuba, São Paulo State. The growth parameters of individuals were estimated by the Bertalanffy growth model, and longevity was estimated with the inverted Bertalanffy equation. The growth parameters were, for females and males respectively: CL∞ = 53.10 mm and 43.23 mm, k = 1.82 year-1 and 2.19 years-1, t0= 1.10 and 0.69. Longevity was calculated to be 2.27 years for females and 2.10 years for males....
