The present study suggests that the observed genetic difference between Atlantic cod, Gadus morhua, off the south and the north coast of Iceland may be caused by natural selection affecting genetic variation at a microsatellite loci (Gmo34). When disregarding this locus from the analysis, no genetic difference was observed between northern and sout...

Genetic variation in whiting Merlangius merlangus was examined using a 621 base pair fragment of the cytochrome c oxidase subunit I mitochondrial gene in 138 individuals sampled from Iceland, Norway and the North Sea. In total 10 segregating sites were observed defining 12 haplotypes. Three of the haplotypes were found at high frequencies (>5 %). A...

Planktivorus Arctic charr had larger eggs than small benthivorous charr and the progeny of the former were longer (total length) at days 125, 145 and 159 after fertilization. Size differences remained significant after the removal of egg size effect on embryo size. Size of hybrid progeny tended to be similar to their maternal pure progeny group, su...

Genetic variation in saithe Pollachius virens was examined using a 460 base pair fragment of the cytochrome c oxidase subunit I mitochondrial gene in 1163 individuals sampled in Canada, Iceland, Faroe Islands and Norway. In all, 43 segregating sites were observed, almost all synonymous, defining 51 haplotypes. High frequency polymorphism was presen...

"Over the years, the paradigm to develop aquaculture as a stand-alone enterprise proved a failure in Malawi due to socio-economic status of the majority of Malawian farmers. Overall, 75% of families cannot feed themselves, producing on average, only 64% of their own food requirements. With the low per capita land holding of about 2 ha, the most com...
