NEW PROPOSED AREA FOR THE ISUNEPCA UWTV SURVEY IN THE GULF OF CADIZ (FU 30)
2022
Vila, Yolanda | Burgos, Candelaria
ISUNEPCA UWTV survey is carried out in the Gulf of Cadiz (UF 30) yearly in spring-summer since 2014, although the first survey is considered as exploratory. The main objective is to estimate a Nephrops abundance index to be use as base of the assessment and advice of this stock. The Nephrops area distribution and coverage of the survey was accepted by the Benchmark Workshop WKNEP in 2016 and this survey was considered as appropriated to providing scientific advice on the abundance of this stock. However, experience acquired during ISUNEPCA survey time series suggests the survey area should be smaller than the current coverage area for this UWTV survey. Therefore, the Nephrops abundance estimate and as consequence the advice of this stock could be affected. A new survey area is proposed based on the analysis of updated and available data.
