Balanced harvesting is the name of a newly proposed approach to fishing which promises the extraction of high and sustainable fisheries yields while maintaining the structure of the ecosystem from which those yields could be obtained. This is to be achieved through exposing all components of ecosystems (from zooplankton to top predators, including seals, sea birds and marine mammals) to a fishing mortality proportional to their size-specific productivity. This study briefly analyses the incompat...

In a recent publication (Froese et al., ICES Journal of Marine Science; doi:10.1093/icesjms/fsv122), we presented a critique of the balanced harvesting (BH) approach to fishing. A short section dealt with the size-spectrum models used to justify BH, wherein we pointed out the lack of realism of these models, which mostly represented ecosystems as consisting of a single cannibalistic species. Andersen et al. (ICES Journal of Marine Science; doi:10.1093/icesjms/fsv211) commented on our paper and s...

The approach to fisheries termed “balanced harvesting” (BH) calls for fishing across the widest possible range of species, stocks, and sizes in an ecosystem, in proportion to their natural productivity, so that the relative size and species composition is maintained. Such fishing is proposed to result in higher catches with less negative impact on exploited populations and ecosystems. This study examines the models and the empirical evidence put forward in support of BH. It finds that the models...

In the News & Analysis story “Court slams Japan's scientific whaling” (4 April, p. [22][1]), V. Morell recounts the recent judgment of the International Court of Justice that the second Japanese scientific whaling program in the Antarctic (JARPA II) shall cease. This decision has given extra weight to a principle that is already contained in most existing scientific and ethical guidelines for research involving the taking of wild animals: Sample sizes (numbers of animals taken) must be justified...

The main consumer-targeted certification scheme for sustainable fisheries is failing to protect the environment and needs radical reform, say Jennifer Jacquet, Daniel Pauly and colleagues.

Negotiations on the future of the International Whaling Commission (IWC) may culminate in a decision at the annual meeting in Morocco from 21 to 25 June that would suspend the current moratorium on commercial whaling and allow commercial catches of fin, minke, sei, and Bryde's whales in the North

In their Report “Whales before whaling in the North Atlantic” (25 July, p. [508][1]), J. Roman and S. R. Palumbi conclude, using genetic markers, that humpback, minke, and fin whale populations in the North Atlantic were once much larger than previously thought, which goes against the current
