About

About the course

Course content

Natural marine stocks: Methods for identification and delimination, milieu factors and geographic distribution range, effects of climatic changes, introduced species, individual growth, sexual maturation, fecundity, stock productivity, recruitment studies and population monitoring. Furthermore; MLY (maximum long term yield), regulation measures (quotas, season closing, “no-fish boxes”, sanctuaries, mesh size, ICES recommendations), inter-specific competition, ballast water, selective fishing gear and its evolutionary effects, “reaction norms”, genetic stock structure, metapopulations, stock contractions and expansions, stock size fluctuations and its effect on the concervation of genetic variability.
Captive stocks: Principles of establisment of brood stocks (local or global, number of parents, genetical variability width), type of selection (family- or mass selection, planned and non-planned genetic change, adaption to captivity milieu, genetic correlations, genetic tagging, pedigrees, software for genetic brood stock management, renewal of genetic material, genetic effects of escapes and introgression into wild stocks, use of genetically modified organisms (GMO, introgressions,), induced sterility, and polyploidy.

Learning outcome

The course will focus on both natural and captive populations (brood stocks) in marine species. The students shall obtain an overview and indepth knowledge of biological and genetic principles for a rational and sustainable management of stocks. In particular, the course will focus on restrictions and problems connected with small population sizes.
