Fish are commonly stocked into impoundments globally, yet their patterns of habitat use in this variable environment are rarely incorporated into the management of stocking density. The movement and distribution of Australian bass Macquaria novemaculata (Perchichthyidae) were monitored in two impoundments to assess whether: (1) impoundment populations exhibit behaviour typical of wild or riveri...

Defining the oceanic habitats of migratory marine species is important for both single species and ecosystem-based fisheries management, particularly when the distribution of these habitats vary temporally. This can be achieved using species distribution models that include physical environmental predictors. In the present study, species distribution models that describe the seasonal habitats o...

Fisheries provide an abundant and predictable food source for many pelagic seabirds through discards, but also pose a major threat to them through bycatch, threatening their populations worldwide. The reform of the European Common Fisheries Policy (CFP), which intends to ban discards through the landing obligation of all catches, may force seabirds to seek alternative food sources, such as bait...

Aim Understanding how fish food webs emerge from planktonic and benthic energy pathways that sustain them is an important challenge for predicting fisheries production under climate change quantifying the role of in carbon nutrient cycling. We examine if a trait-based community model using traits maximum body weight vertical habitat strategy can meet this by globally representing web diversity....

Hundreds of thousands of seabirds are killed each year as bycatch in longline fisheries. Seabirds are predominantly caught during line setting but bycatch is generally recorded during line hauling, many hours after birds are caught. Bird loss during this interval may lead to inaccurate bycatch information. In this 15 year study, seabird bycatch was recorded during both line setting and line hau...

The fishing ground is identical and closely related to chlorophyll-a abundance in the waters, associated with its fisheries potential. This research has been conducted determine concentration distribution of seas, especially Fisheries Management Area (FMA) 712 encompassing Java Sea. analysis used monthly time-series data collected from satellite imagery over last 11 years, taken through ERDDAP ...

Rastrelliger brachysoma, a short mackerel, is significant pelagic fish that common in the fisheries Gulf of Thailand. The management stocks prerequisite for conservation strategies and profitable fisheries. Morphological character differences between species provide method identifying stocks. This study was aimed to identify stock population mackerel Upper Middle specimens were collected from f...

Route optimization methods offer an opportunity to the fisheries industry enhance their efficiency, sustainability, and safety. However, use of route Decision Support Systems (DSS), which have been widely used in shipping industry, is limited case fisheries. In first part, this work describes fishing routing problems, reviews state-of-the-art applied introduces a general framework for decision ...

Traditional regionalization methods in fisheries based on provinces or major fishing areas, includes large and arbitrary grids in which basic statistics or inferences on distribution or abundance are made. We describe a method for regionalization and analysis of fishing activities for small pelagic fisheries in the Gulf of California based on spatial patterns of landing and catch data in a Geog...
