Cod spawning hot spots mapped
work on African primates. Field stations at three sites in Tanzania, two in Congo, and one each in Gabon and Guinea will be supported. Work on the ecology and behaviour of Borneo orangutans is also part of the programme. Apart from the work on primates, the centre is also active with many other species, including whales and dolphins. With Japan’s continuing controversial whaling operations in t...
متن کاملMapping the spawning grounds of North Sea cod (Gadus morhua) by direct and indirect means.
Despite recent evidence for sub-stock structuring, North Sea cod are assessed as a single unit. As a consequence, knowledge of sub-stock trends is poor. In particular, there are no recent evaluations of which spawning grounds are active. Here we report results from the first ichthyoplankton survey to cover the whole North Sea. Also, this survey, conducted in 2004, was the first to make extensiv...

متن کاملFrequent skipped spawning in the world's largest cod population.
Life-history theory suggests that animals may skip reproductive events after initial maturation to maximize lifetime fitness. In iteroparous teleosts, verifying past spawning history is particularly difficult; the degree of skipped spawning at the population level therefore remains unknown. We unequivocally show frequent skipped spawning in Northeast Arctic cod (NEAC) in a massive field and lab...
