Abstract

This working document provides a brief description of the sampling, laboratory analysis and estimation procedures conducted by IEO in the VIIIb ICES division to obtain the Spawning Stock Biomass (SSB) estimate for 2014 in this area by the application of the Daily Egg Production Method. The Working Document provides in addition preliminary estimates of all parameters of the DEPM and of SSB.

2. DEPM 2014. Preliminary Egg Results for the Atlanto-Iberian Sardine ICES VIII and IXa

Abstract

The triennial DEPM for estimation of sardine spawning biomass for the Atlanto-Iberian stock areas IXa – VIIIc and VIIIb up to 45 º N took place in the S and W (IPMA) from 15th March to 26th April and in the N (Galicia, Cantabrian Sea and French coast, IEO) between 29th March and 21st April. The whole area was surveyed however the Portuguese survey occurred much later than usual and suffered several interruptions; part of IPMA´s DEPM survey was conducted simultaneously to the acoustics survey onboard the same vessel. The number of fishing samples was maintained at levels similar to other years but it was evident that sardine schools were less available than during previous surveys in particular in the western and northern shores. Preliminary estimates highlighted a sharp decrease in egg production from 2011 to 2014; this pattern was particularly clear in the northern stratum.

Abstract

This document presents the results of the SAREVA0408 ichthyoplankton survey conducted by IEO (Instituto Español de Oceanografía). This survey was carried out on board R/V Cornide de Saavedra during April 2008. The covered area was the North and North-western Iberian Peninsula waters and the inner part of the Bay of Biscay (from 42°N to 45°N).The present paper includes data on sardine (Sardina pilchardus) egg distribution and abundance from the SAREVA0408 survey, as well as the estimation of daily egg production (DEPM) for sardine in the North Spanish Atlantic, Cantabrian waters and south of the Bay of Biscay.

Abstract

This document presents the results of the analysis from sardine (Sardina pilchardus) egg densities in relation to environmental (temperature, salinity) and geographic (longitude, depth) variables. Data were obtained from the SAREVA0408 ichthyoplankton survey conducted by IEO (Instituto Español de Oceanografía) in April 2008. Quotient analysis, temperature-salinity plots and time distribution for eggs per stage of development, were employed to study spawning habitat of the sardine off north Spanish Atlantic, Cantabrian waters and south of the Bay of Biscay.
