Feeding performance of juvenile hatchery-reared spotted seatrout Cynoscion nebulosus.
The feeding performance of individual hatchery-reared (HR) and wild juvenile spotted seatrout Cynoscion nebulosus was compared across a series of six 1·5 h feeding exposures over a 3 day period in a controlled experiment. The predation cycle served as a context for discerning feeding performance elements. The experimental design facilitated assessments of the effects of experience, motivation d...
متن کاملCatch-and-Release Mortality of Spotted Seatrout in Texas
—Catch and release is becoming more common as a management tool in marine recreational fisheries. Clearly, a critical factor in determining different management scenarios that use this strategy is postcapture survival. We investigated the mortality associated with catch and release in the fishery for spotted seatrout Cynoscion nebulosus in south Texas. Specifically, this study investigated the ...
متن کاملYield and Biomass-per-recruit Analysis of Tiger Tooth Croaker (Otolithes ruber) in the Northwest of the Persian Gulf
Effects of age at first capture (tc) and fishing (F) as well as natural mortalities (M) on yield and biomass-per-recruit of tiger tooth croacker, Otolithes ruber were evaluated in the northwest of the Persian Gulf using the Beverton-Holt model. The yield-per-recruit (Y/R) was 175 (g/r), which was less than maximum yield-per-recruit value (217 (g/r)) at fishing mortality of 1 year-1. Current ...
متن کاملAn estimation of growth parameter, mortality rates and yield-per-recruit for beluga (Huso huso) living in Caspian Sea
This paper presents the results of study on age, growth, mortality rates and yield-per-recruit of Beluga (Huso huso) living in Caspian Sea. The mean length of successive years, mortality rates and yield-per-recruit studies indicated that at present the resource is under heavy fishing pressure. For the female Beluga growth was regarded as comprising of three stages, and the von Bertalanffy param...
متن کاملRelative yield-per-recruit and management strategies for Cynoscion acoupa (Perciformes: Sciaenidae) in Lake Maracaibo, Venezuela.
Acoupa weakfish, Cynoscion acoupa, in Lake Maracaibo is subject to intense commercial fishing by an artisanal fleet, and a recent decrease in fish size observed from landings is of concern. This fishery has not yet been modeled, and its assessment and the establishment of management practices to overcome the current overfished condition are urgently needed. To address this, we used recent and p...
