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...

Adriano Macia is a PhD candidate in the Systems Ecology Department, University of Stockholm. He holds a MSc degree in Marine Zoology from the University of Goteborg, Sweden. He is a lecturer in Marine Biology at the University Eduardo Mondlane, Maputo. He has research interests on the interlinkages between mangroves and commercial penaeid shrimps (the ecological role of mangroves as nurseries f...

The green turtle (Chelonia mydas) has been a species of global concern for decades. As an attempt to study health status of nesting green turtles, Blood biochemistry and hematological values were obtained from 18 clinically normal, nesting female green sea turtles on the northern coast of the sea of Oman. Mean curved carapace length (CCL) was 111±4 cm with a range of 103—122 cm. Barnacles were ...

A procedure is proposed by which recruit numbers and parental biomass of shrimps stocks can be derived, given a series of catch-per-effort data and estimates of a few ancillary variables. In the Gulf of Thailand, shrimp recruitment decreased with decreasing egg production, but increased with decreasing total (mainly fish) standing stock. The net result of these counteracting effects was an over...

Several immune-related molecules in penaeid shrimps have been discovered, most of these via the analysis of expressed sequence tag libraries, microarray studies and proteomic approaches. These immune molecules include antimicrobial peptides, serine proteinases and inhibitors, phenoloxidases, oxidative enzymes, clottable protein, pattern recognition proteins, lectins, Toll receptors, and other h...

The macro-epibiotic communities of sea turtles have been subject to growing interest in recent years, yet their micro-epibiotic counterparts are almost entirely unknown. Here, we provide the first evidence that diatoms are epibionts for all seven extant species of sea turtle. Using Scanning Electron Microscopy, we inspected superficial carapace or skin samples from a single representative of ea...

A novel PCR-RFLP method has been developed for the identification of six commercially relevant penaeid shrimp species in raw and processed food products. The method can be completed within 8 h. To implement the method, PCR amplification with the crustF/crustR primers, targeted to the amplification of a ca. 181 bp region of the cytochrome b (cytb) mitochondrial gene in penaeid shrimps, was coupl...

We examined sea turtle consumption and illegal trade in Baja California Sur (BCS) using data from (1) bimonthly surveys at beaches, fishing camps and dumpsites and (2) semi-structured interviews with fishermen. From March 2006 to February 2008, we found the carcasses of 1014 sea turtles; the meat of 461 of these turtles (45.5%) had been consumed. The East Pacific green turtle Chelonia mydas was...

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 ...
