this study was conducted to estimating the amount of non-standard sizes (with lengths less than lm50) fishes of shrimp trawls in the hormozgan province coastal water during shrimp fishing season. sampling was carried out using the tabas otriger commercial trawler during 55 hauls. eight commercially valuable species including pampus argenteus, parastromateus niger, plicofollis dussumieri, saurid...

Shrimp trawling represents an important fishing métier in South India, generating high levels of employment and economic value. It is also a contested métier, ostensibly contributing to environmental degradation and social inequality. This paper investigates the job satisfaction of crew members (captains and workers) on board the shrimp trawlers of Chennai (former Madras). Research took place i...

The red shrimp, Aristeus antennatus (Risso, 1816), is one of the most important resources for the bottom-trawl fleets in the northwestern Mediterranean, in terms of both landings and economic value (Demestre and Lleonart, 1993; Demestre and Martin, 1993; Maynou et al., 2006). One of the ports obtaining the highest yields in the area is that of Blanes (Irazola et al., 1996; Bas, SCIENTIA MARINA ...

The diets of gurnards Aspitrigla cuculus and Eutrigla gurnardus, lesser-spotted dogfish Scyliorhinus canicula and whiting Merlangius merlangus were examined to determine whether they migrated into recently trawled areas to feed on animals that may be damaged or dislodged by the action of a 4 m beam trawl. Gurnards and whiting increased their intake of prey after an area had been fished. In part...

This paper is a comprehensive study of the shrimp trawl by- catch from Bushehr coastal waters (N. Persian Gulf). Sampling operation was carried out in two shrimp fishing seasons using the (Saber and Jahanara) commercial trawlers Generally, 87.5% of the total catch was by-catch and 12.5% was target species (shrimp). The catch composition included: 114 species from 45 teleostei families, 13 speci...

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...

Bycatch studies have largely ignored population level effects on fish species of little commercial interest. Here we analyze bycatch of the lined seahorse (Hippocampus erectus) in the bait-shrimp trawl fishery in Hernando Beach, Florida, providing the first fisheries data for this species. Based on catch per unit of effort (CPUE), size, sex, and reproductive status of trawled H. erectus, 1) app...

speckled shrimp (metapenaeus monoceros), is a commercially important prawn in the embayments and estuaries of the mediterranean sea. it is originally a lessepsian species which had migrated from the red sea into the mediterranean sea through the suez canal. this study was carried out in the north-eastern mediterranean sea between november 2009 and october 2010 with monthly sampling of speckled ...
