Size selectivity and catch efficiency of four codends were tested compared for mantis shrimp ( Oratosquilla oratoria ) in demersal trawl fisheries the South China Sea (SCS). These differing mesh shapes, diamond (T0) diamond-mesh turned 90° (T90) with sizes 30 35 mm, respectively. The results demonstrated that T0 codend a lower size, presented poorer selective properties target species, while si...

Incidental catch of marine species can create ecological and economic issues, particularly for endangered species. The smalltooth sawfish (Pristis pectinata) is endemic to the Atlantic Ocean listed as Endangered in US Species Act. One its major threats bycatch mortality commercial fisheries. Despite protection afforded by Act, are still captured Acoustic satellite tag data collected on 59 betwe...

Laboratory experiments and field observations in shallow water habitats in the Navesink River /Sandy Hook Bay estuarine system (NSHES), New Jersey, USA, were used to examine the predator–prey relationship between the striped searobin (Prionotus evolans: Linnaeus) and young-of-the-year (YOY) winter flounder (Pseudopleuronectes americanus: Walbaum). Striped sea robins (121–367 mm total length [TL...

The catch of large quantities sublegal-sized fish and shrimp is a pervasive feature bottom trawl fisheries, particularly in the Mediterranean demersal mixed fisheries where regulations traditionally allow small mesh sizes. To address these concerns, two net selectivity trials were carried out 2019 2020 on fishing grounds worked by fleet Spanish Mediterranean, under normal commercial operating c...

A bioeconomic model was built to assess the contribution of more selective trawl nets objectives European Multi-Annual Plan for demersal fisheries in Western Mediterranean (WM MAP). The biological submodel parameterized with age-structured population parameters five target stocks WM MAP (European hake, red mullet, deep-water rose shrimp, Nephrops and shrimp) a sixth stock combining remaining co...

Since 1991, the number of penaeid shrimp occurring in Virginia waters Chesapeake Bay has steadily increased, prompting an interest developing a fishery. Although development fishery region could bring economic benefits, may be hampered by presence disease syndrome known as black gill (sBG). The objectives our study were to (1) describe spatial distribution and abundance patterns Bay, (2) relate...

Media Independent Handover (MIH) is an emerging standard which supports the communication of network-critical events to upper layer mobility protocols. One of the key features of MIH is the event service, which supports predictive network degradation events that are triggered based on link layer metrics. For set route vehicles, the constrained nature of movement enables a degree of network perf...
