PRIMER REGISTRO DEL TIBURÓN MAKO ALETA LARGA, ISURUS PAUCUS GUITART (CHONDRICHTHYES: LAMNIDAE), PARA EL CARIBE COLOMBIANO Boletín de Investigaciones
Gámez Barrera,Dáninso; Nieto Alvarado,Luis; Morón Granados,Eliana; Caldas,Juan Pablo; Correa,José Luis.
The occurrence of the longfin mako Isurus paucus is reported in the Colombian Caribbean for the first time. Three specimens were captured, one was caught by artisanal fishermen in Concha bay and the two others were captured in the open sea by an industrial fishing boat. This is the first evidence of the occurrence of this species in shallow and offshore waters of the Colombian Caribbean.

Using body mass index (BMI) to estimate mercury contamination of the blue shark (Prionace glauca) and the shortfin mako (Isurus oxyrinchus) ArchiMer
Biton Porsmoguer, Sebastian; Dekeyser, Ivan; Banaru, Daniela; Bouchoucha, Marc; Marco-miralles, Francoise.
Blue shark (Prionace glauca) and shortfin mako (Isurus oxyrinchus) specimens were caught in the North-eastern A tlantic O cean by S panish and Portuguese longliners. They are considered as top-predators, particularly susceptible to bioaccumulate mercury (Hg). The H g mean levels in blue shark and shortfin mako were 0.4 (SD = 0.3 mg kg-1) and 0.5 (SD = 0.9 mg kg-1), respectively. The body mass index (BMI) was tested to demonstrate the accumulation of H g in these two top-predators, taking into account size (TL, cm) and mass (W, kg) simultaneously. The comparison of these three methods showed that the BMI could be a relevant biological indicator of the accumulative H g process for sharks.
