Abstract

Venezuelan blue shark catch estimates commenced to be recorded separately and reported to ICCAT in 2004, previously was recorded under the shark category (SHX). In this document statistical data from various sources, official statistics, publications, grey literature, expert opinion, and several ICCAT monitoring projects for data improvement in Venezuela were used to reconstruct the specific blue shark catch for the period of 1986-2013 caught by the industrial longline fishery and the artisanal drift-gillnet fishery for the period 1991-2013. Information on sex ratio at size of blue shark from the Venezuelan pelagic longline fishery and the artisanal drift-gillnet fishery is presented for the period 1994-2013. The document analyzes the spatial and temporal distribution of 1424 sharks (744 females and 654 males, and 26 sex unknown) from both fisheries.
