“…Females of Mustelus higmani attain greater size than males (Compagno 1984, Cervigón and Alcalá 1999, Compagno et al 2005), a common aspect for different species of the genus Mustelus, such as M. (Compagno et al 2005) and M. punctulatus (Saidi et al 2009). The largest body sizes previously reported for M. higmani were 75 cm and 59 cm TL for females and males, respectively (Tavares et al 2010).…”

“…Also, some large remains of fish (possibly of the family Ariidae) were observed, suggesting that occasional large preys are trapped by some type of group hunt behaviour or scavenger feeding. Saidi et al (2009) suggested the need for further research to corroborate the hypothesis of scavenger feeding for larger fish and to document ontogenic changes in the diet of M. punctulatus to consuming larger preys (like fish and molluscs) at greater sizes.…”

Summary:Mustelus higmani is categorized as "least concern" according to the red list of the International Union for Conservation of Nature, but gaps in population trends occur in most of its distribution range. In Venezuela, this species has local importance because it is part of typical dishes. The aim of this work is to analyse the population structure, reproduction and feeding of M. higmani from Margarita Island's artisanal fishery landings for management purposes. Between 2006 and 2008, 2223 specimens were analysed: 1156 females (24.8-88.4 cm total length [TL]) and 1067 males (20-69.2 cm TL). Temporal variations in sex ratio and length class structure were detected. Changes in body size were detected throughout different years of sampling. A decrease in TL and an increase in immature specimens in the catch were observed in 2008. Mean length at maturity (L 50 ) was estimated at 46.7 cm TL for females and 47.6 cm TL for males. Female fecundity was 4±1.8 embryos (n=388). Length at birth was between 20 and 29 cm TL, and no differences in sex ratio were detected for embryos. Feeding analyses (n=266 stomachs) showed a diet mainly based on decapod crustaceans, small fish, stomatopods and cephalopods. The trophic level was 3.3, which shows feeding based on benthic and demersal species of the continental shelf, especially crustaceans.Keywords: shark fishery; elasmobranch; Chondrichthyes; artisanal fishery; Caribbean.Longitud de captura, reproducción y alimentación de la viuda amarilla, Mustelus higmani (Carcharhiniformes: Triakidae), en isla de Margarita, Venezuela Resumen: Mustelus higmani está catalogada con "preocupación menor" en la lista roja de la IUCN, sin embargo existen vacíos de información sobre la tendencia poblacional en la mayoría de su rango de distribución. En Venezuela, esta especie tiene gran importancia local porque es parte de platos típicos tradicionales. El objetivo del presente trabajo es analizar la estructura poblacional, reproducción y alimentación de los ejemplares de M. higmani provenientes de los desembarques de la pesca artesanal de isla de Margarita, para contribuir con el manejo de la especie.

Fueron detectadas variaciones temporales en la proporción sexual y estructura de longitudes. Una disminución de la longitud total y un incremento de organismos inmaduros fueron observados durante el 2008. La longitud media de madurez sexual (L 50 ) fue estimada en 46.7 cm LT para las hembras y 47.6 cm LT para machos. La fecundidad uterina fue estimada en 4±1.8 embriones (n=388). Longitud cercana al nacimiento entre 20-29 cm LT, sin diferencias en la proporción sexual de embriones. Los análisis de alimentación (n=266 estómagos) muestran una dieta basada principalmente en crustáceos decápodos, peces pequeños, estomatópodos y cefalópodos. El nivel trófico calculado fue 3.3.

In the present work, an overview of the demersal (sharks-chimaera) and bottom dwelling . Results suggest that most of the Chondrichthyes in South of Sicily are in a steady state, although in the last few years, they seemed to recover. The spatial distribution of sharks-chimaera in the geographical sub-area (GSA) 16 is mainly concentrated in the southern and north-western zones. Nevertheless, possible management actions to promote the recovering of these very important ecological and threatened species are discussed.
