At present, the majority of fisheries are monitored and regulated in areas which are delineated by arbitrary ICES boundaries which do not necessarily have logical or consistent relationships with biological processes or fish movements. The biogeographical identification of Channel stocks is, therefore, an important step towards developing a rational strategy for the management of their fisheries. This synthesis is based on the wide available knowledge which has not been yet entirely exploited with the purpose of stock identification, for 25 commercially important species in the Channel. In addition, principal technics for stock identification are reviewed likewise environmental characteristics of the Channel, which represent fundamental components in...

Caractérisation et connectivité des Habitats Ecologiques Essentiels des stades adulte et juvénile du bar européen

Autores: Dambrine, Chloe.
Essential Fish Habitats host, at least, one stage of their life cycle. As they can be distant, maintaining their connectivity is essential for the closure of fish life cycle and populations’ sustainability. This thesis focused on the connectivity between spawning areas and nurseries of European seabass. Its main spawning areas have been characterised using a non-linear geostatistical approach applied to highly resolved fishery data. A Bayesian spatio-temporal model showed that they are mainly explained by a stable spatio-temporal structure, rather than by hydro-climatic factors. A bioenergetics model (DEB) over the entire life cycle of seabass was developed and validated for the early life stages. It showed that larvae and juveniles are resistant to low...

Larvae occurrences of Rhamdia quelen (Quoy &amp;amp; Gaimard, 1824) (Siluriformes: Heptapteridae) in an area under dam influence in the upper Paraná River region, Brazil
Provedor de dados: 83
Autores: Silva,Evelyn B. da; Picapedra,Pablo H. dos Santos; Sanches,Paulo V.; Rezende,Renato E. O. de; Gavião,Aline M.; Mendonça,Marcos M.; Gonçalves,Edilaine D. V.; Conte,Rafael Bier.
Rhamdia quelen (Jundiá) is a catfish species of great interest to fish producers and researchers due to several favorable characteristics for inclusion in the Brazilian list of commercially raised fish. It has a wide geographical distribution, with occurrences reported from Central Argentina to South Mexico. Studies on the biological aspects of this species have been limited to captive adult fishes that were researched for farming purposes. Research related to ichthyoplankton has provided valuable information on spawning periods and sites and other aspects of breeding for numerous species of fish. This information is crucial for implementing management and protection strategies for these species. The studied floodplain is located in a lotic remnant between...
