Project CRESH "
Cephalopods: Recruitment and habitat monitoring
pre-recruits Channel
After being a partner in several European projects for the study of
Cephalopods, University of Caen Basse-Normandie took the initiative to be
"leader" of the INTERREG IVA CRESH "for the study of recruitment
and stages before entering the fishery Channel (eggs and juveniles).
Cuttlefish and squid to handle shared resources are exploited
by both English and French fishermen. Fast growing species and
short-lived abundance depends on recruitment (the arrival of juveniles
harvestable stage) that is sensitive to environmental fluctuations. At
spawning, females lay their eggs on the bottom and sometimes on criminal
Describe the natural habitat of spawning areas is needed to understand
seabed which are essential to the renewal of these resources. The study
survival of juveniles and ecology of pre-recruitment stages fits in
the "EAF" and received the label "Channel Challenge"
among the projects which involved IFREMER.
The project CRESH ", carried by the joint laboratory between the University of Caen
Basse-Normandie and IFREMER UMR 100 million of Physiology and Ecophysiology
Marine molluscs (PE2M) is arranged symmetrically with English side and
French partner universities, institutes of fisheries, and
industry representatives.
In the case of cuttlefish it will allow the observation of existing spawning
on both coasts French and English that it implements a set
tools (biochemical indices, isotope, genetic markers,
trace elements) to try to assess the contribution of different sectors
recruitment takes place at the center of the channel.

These new data will be reflected in improved models
stock assessment and better understanding of this habitat will provide
other criteria that are relevant to all managers for sustainable management
these resources.
