the bottom trawl selectivity parameters (22mm cod-end mesh size) were determined for saurida undosquamis , mullus barbatus , upeneus pori , and pagellus erythrinus along karatas coasts of turkey in northeastern mediterranean waters during fishing season for the year 2002-2003. the lengths at first capture (l 50 ) values for s. undosquamis , m. barbatus , u. pori and p. erythrinus were 12.57, 9....

The reproductive features of the giant red shrimp, Aristaeomorpha foliacea, were investigated in the southern Tyrrhenian sea by experimental trawl sampling. The annual length-frequency distribution showed a multimodal trend in females, ranging between 16 and 67 mm carapace length (CL), and a unimodal trend in males (18-45 mm CL). Mature males occurred in different proportions all year round, wh...

The trawl fishery of the Mediterranean coast of Israel was analyzed vis á vis catch and fishing effort for the years 1949-2010. The Maximum Sustainable Yield (MSY) was calculated using the Fox surplus-yield model and was found to be 1,413 ton per annum using 1,415 units of effort (fishing days X engine power divided by 1000). Only during nine years (1997-2005) did fishing effort exceed the valu...

this study was conducted for estimation of bycatch shrimp trawl from fishing grounds of hormozganprovince.sampling operation was carried by commercial trawler around hormoz and qeshm islandduring fishing season in october and november 2012. towing duration was between 1 to 3.5h(2±0.08h). contribution of bycatch and target species was 86.26% (18918.80 kg) and 13.74%(3014.22kg) respectively. by-c...

This study investigated spatial and temporal patterns in distribution, population structure and diet of Bolin's lanternfish Protomyctophum bolini, Tenison's lanternfish Protomyctophum tenisoni and gaptooth lanternfish Protomyctophum choriodon in the Scotia Sea using data collected by midwater trawl during spring, summer and autumn. Protomyctophum bolini was the most abundant species of the genu...
