Animals are primarily limited by their capacity to acquire food, yet digestive performance also conditions energy acquisition, and ultimately fitness. Optimal foraging theory predicts that organisms feeding on patchy resources should maximize their food loads within each patch, and should digest these loads quickly to minimize travelling costs between food patches. We tested the prediction of h...
Background Bangladesh is basically a low lying flat land country, is endowed with enormous inland fishery resources which contribute a significant part of freshwater fish production. Inland fisheries in Bangladesh contain different types of water bodies’ character e.g. flowing rivers, beel—usually deeper depression in the floodplain, haor—extensive low lying areas comprising several perennial b...
Marine protected areas (MPAs) are one tool that can be used in the comprehensive management of human activities in areas of the ocean. Although researchers have supported using MPAs as an ecosystem management tool, scientific research on MPAs in areas other than fisheries and fisheries management is limited. This paper presents a model for designing marine protected areas that protect important...
OR RE CT ED P Abstract The Pacific shrimp fishery is the most economically important and ecologically impactful fishery in Mexico. Strong export markets have had a tremendous influence on the technological development and structure of this fishery. This article describes the historical development, current status, ecological impacts and management of the open ocean trawling component of the shr...
To date, none of the fisheries in the U.S. Pacific Islands Region is managed under a catch share program. In light of the NOAA policy to encourage the use of catch shares as a fishery management tool, the Western Pacific Fishery Management Council (WPFMC) listed six commercial fisheries, including the Hawaii pelagic longline fishery, the largest in the region, as potential candidates for catch ...

Seabirds as offshore wildlife resources have largely been unstudied by wildlife managers until recently. Brown pelicans (Pelecanus occidentalis californicus) in Southern California Bight (SCB) have received special attention in the past under the Endangered Species Act of 1973 (ESA). Special consideration is given to species with endangered status in commercial fishery management plans mandated...
The studies carried out in this work made it possible to characterize the dynamics of raw material base aquatic biological resources Russian waters Chukchi Sea 1997–2020 and evaluate its value at present stage. marine fish invertebrates varied from 5,4 450,1 thousand tons (with an average 196,7 tons). It was based on – 189,0 (96,1% all resources), stocks 7,7 (3,9%). Estimates commercial WBR bio...
