Artisanal shark fisheries have been an important source of food and employment in Mexico for many years. In the Gulf Mexico, this multispecific fishery is based on seasonal abundance several teleost species. To obtain biological information needed to manage conserve stocks, intensive monitoring artisanal landings was undertaken from November 1993 December 1994. The State Campeche had highest effort. October 1994 monthly catch per unit effort all species areas combined (27.2 sharks trip)....
Abstract Fish at the top of food chain bioaccumulate and biomagnify toxic metals including mercury (Hg), a higher rate than nonpredatory fish. However, although some predator fish species are important in human diet, risks for consumers Mexico difficult to evaluate due scarce baseline information available. In present article, data on total (THg) concentrations found edible tissues different sharks, rays, large pelagic fishes groupers from Gulf California presented compared with national...
El tiburon azul es una de las principales especies capturadas en la pesqueria artesanal costa noroeste de Mexico. En ella, se estimo edad y el crecimiento mediante el conteo bandas centro vertebras de 204 tiburones utilizando nitrato plata para tenir los centros. Los encontraron un rango tallas entre 81 270 cm longitud total (LT), con promedio de 165 �} 35 proporcion sexual machos hembras de 2:1. presentaron LT entre (150,3 �} 32,3 cm, n=593) mientras que entre 90 252 TL (162,7 37,5 n=324)....
We determined the Hg content of blood, placenta and umbilical cord 20 pregnant females viviparous Pacific sharpnose shark, Rhizoprionodon longurio livers embryos contained in their right left uterus, aiming to provide information on amount this metal offloaded during pregnancy by mother embryos. varied close or higher than one order magnitude all tissues showed decreasing trend: maternal blood > embryonic livers, with significantly lower blood. There were highly significant correlations...

The Gulf of California supports the largest ray fishery in Mexico.Sonora is a major ray-fishing state, reporting 56% (live weight) Pacific Ocean rays production.Bottom-set gillnets are principal fishing gear deployed this artisanal fishery.In absence long-term monitoring and complex biological data for stock assessment, an understanding selectivity properties can provide basis implementation standard mesh-size as regulation tool management.Ideally, gillnet parameters determined from trials...
The banded guitarfish, Zapteryx exasperata , is a common species in the artisanal elasmobranch fisheries Gulf of California. Fishery-derived specimens were examined to determine critical aspects reproductive biology this poorly known group rays. Two functional testes and ovaries found males females respectively. Median size at maturity (L 50% ) for was 64 cm total length (TL) 69 TL. Average gravid 78.8±3.8 Histological analysis showed no evidence sperm storage oviducal gland. Gestation...
We report on the proportion of maturity stages as a function size Pacific sharpnose shark Rhizoprionodon longurio. Based development internal and external organs, males females were classified immature or mature. A logistic model was fitted to develop curve estimate length at which 50% individuals are mature (L50%). This species has an annual reproductive cycle its birthing season is from April July, with June main month. For males, L50% = 100.61 cm total (TL) Φ 2.57, for females, 92.9 TL...
Abstract Lipid composition by class, fatty acids, natural antioxidants (carotenes, tocopherols) and physicochemical characteristics of liver oil from three commercial rays, Rhinoptera bonasus (Chucha), Aetobatus narinari (Pinta) Dasyatis americana (Bala) the Gulf Mexico were analyzed. Liver yield for R. , A. D. 43.04, 41.2 38.2% (wet weight), respectively. Triacylglycerols most abundant lipid class in (68.9%), (85.9%) (81.6%), while sterols esters, sterols, di‐ monoacylglycerides, polar...
