The fishery for mobulid rays, also known as devil rays, has been practiced in the Bohol Sea for over a century yet very little is known about its history and characteristics. This study provides the first detailed description of the mobulid ray fishery in the Bohol Sea, Philippines. It describes the history and evolution of the fishery from the 19th century to 2013. It characterizes the fishery...

1. Fisheries bycatch has been implicated in declines of many long-lived marine vertebrate populations, but bycatch impacts on these populations vary according to spatio-temporal overlap in fisheries operations and critical ontogenetic habitat, as well as to characteristics of fishing gear. 2. To provide a framework for comparing the relative impacts of different fisheries on populations of logg...

In fishes, physiological and behavioural traits can correlate with vulnerability to capture fishing gears, highlighting the capacity of fisheries selection drive phenotypic change in exploited populations. There remains a paucity information regarding how different gears may select on relationships between individual across environmental gradients. By simulating process trawl trap using wild mi...

Abstract The number of seals in the Baltic Sea has increased dramatically recent years. While growing seal populations are associated with a thriving marine environment, interact coastal fisheries causing significant damages to catches and gears. One fishery that is severely affected cod where negative impact believed by many threaten existence fishery. This article empirically investigates wha...

The aim of the present study was to evaluate the illegal Silver pomfret catch by fixed gill-nets in Hormozgan inshore waters (Qeshm Island). Sampling was performed in Bandar Laft estuaries through three fishing boats between April to July 2015. The fishing gears were the nylon mono-filament fixed gill-net with 6.5 cm mesh size (bar), 200 m length and 8-10 m height. The non-parametric bootstrap ...

Abstract Stock overexploitation, bycatch, discards and gear impacts on the environment are outstanding issues for Mediterranean fisheries. The adoption of alternative fishing gears is an appealing solution to ensure a more sustainable exploitation resources. We discuss pros cons pots as by reviewing their main designs, spatial distribution target species in basin. assessed technical factors aff...
