Results for capelin from the surveys conducted by Spain in the NAFO Regulatory Area of Div. 3NO, 1995-2015

Since 1995, a stratified random spring bottom trawl survey in the NAFO Regulatory Area of Div. 3NO has been conducted by Spain every year. In 2001, the trawl vessel was replaced in the realization of the survey; a comparative survey between both vessels was made to transform the historical time-seri...

Description
Summary:Since 1995, a stratified random spring bottom trawl survey in the NAFO Regulatory Area of Div. 3NO has been conducted by Spain every year. In 2001, the trawl vessel was replaced in the realization of the survey; a comparative survey between both vessels was made to transform the historical time-series into the new vessel index. The transformed entire series of mean catches and biomass distribution for capelin (Mallotus villosus) are presented for the period 1995-2000, and the no-transformed data for the years 2002-2015. In 2001, there are data from both vessels. The standard deviation is shown for biomass. Biomass fluctuated during all the period, and peaked in 2012. SI
