This study investigated the contribution of shrimp stocks in supporting the production of valuable predator species. Fishery-independent data on white shrimp, brown shrimp, and selected fish species (spotted seatrout, red drum, and southern flounder) were collected from 1986 to 2014 by the Texas Parks and Wildlife Department, and converted to catch-per-unit effort (CPUE). Here, the associations...

Abstract North American fisheries management agencies commit considerable resources to managing reservoir for Channel Catfish Ictalurus punctatus , which often includes stocking. However, population characteristics vary greatly among reservoirs, resulting in variable and unpredictable fishery quality. We sampled populations 44 Ohio reservoirs with tandem, baited hoop nets understand relationshi...

Potential of resource commodities contained in the waters Bali Strait needs to be studied for level utilization and sustainability. This research aimed analyze conditions lemuru fish resources sustainability status fisheries based on four aspects, namely ecological, economic, social, technological dimensions. Commodity condition is carried out with Catch Per Unit Effort (CPUE) analysis, while u...

The Mayan octopus (Octopus maya) and the American (O. americanus) are two species that support fishery on Campeche Bank. large-scale fleet catches both species. However, landings recorded as in official statistics, this causes a problem for management of fishery. Bank was studied using model based data from interviews with skippers. A total 180 valid were conducted base ports Progreso Yucalpete...

Bycatch studies have largely ignored population level effects on fish species of little commercial interest. Here we analyze bycatch of the lined seahorse (Hippocampus erectus) in the bait-shrimp trawl fishery in Hernando Beach, Florida, providing the first fisheries data for this species. Based on catch per unit of effort (CPUE), size, sex, and reproductive status of trawled H. erectus, 1) app...

Nutrient fluctuations and climate warming can synergistically affect trophic dynamics in lakes, resulting in enhanced symptoms of eutrophication, thereby potentially counteracting restoration measures. We performed a long-term study (23 years) of zooplankton in Danish Lake Søbygaard, which is in recovery after nutrient loading reduction, but now faces the effects of climate warming. We hypothes...

Growth of sympatric populations of three important sport fish species: bluegill Lepomis macrochirus, largemouth bass Micropterus salmoides and channel catfish Ictalurus punctatus, in 14 Illinois reservoirs was assessed in an attempt to relate size-specific growth to environmental conditions. Multiple regression relationships for most species and size classes explained a large percentage of the ...

The forced expiratory manoeuvre was first described by Tiffeneau and Pinelli working in Paris (France), in December 1947, who proposed measurement of the "pulmonary capacity usable on exercise" (capacité pulmonaire utilisable à l'effort) (CPUE), the maximal volume expelled in one second after a deep inspiration. It was intended to replace the measurement of the maximum breathing capacity, a dif...

The synergistic effects of fishing, climate and internal dynamics on population fluctuations are poorly understood due to the complexity of these interactions. In this paper, we combine time series analysis and simulations to investigate the long-term dynamics of an overexploited population in the Mediterranean Sea, and its link with both fishing-induced demographic changes and hydroclimatic va...
