Fish certification scheme shows its true colours
Several landmark studies have, over the past 20 years, highlighted the problem of mislabelled fish. One-third of fish on sale in the US is not the species it is sold as, and one-quarter of cod and haddock sold in Ireland is neither of these. Now an exercise in eco-forensics has found that the certification scheme run by the Marine Stewardship Council (MSC), a global not-for-profit organisation, offers a way of ensuring you get what you think you're buying.

Fishing skews sex ratios in fish
Population crashes in many species of reef fish may be linked to an excess of males brought about by fishing - and imposing quotas won't remedy the situation. In many species, particularly those where individuals can change their sex, each fish produces fewer young as the population density drops. The research suggests that marine protected areas are a better strategy for conserving populations than fishing quotas. Protected areas maintain the density of populations whereas quotas may still allow populations to decline, increasing the rate of sex change.

Submarine robots learn teamwork
Studying the deep ocean floor is cumbersome, expensive and dangerous. The majority of exploration efforts have to employ an autonomous unmanned vehicle (AUV), which works without control cables. But many AUVs are specialised, they cannot travel far alone and they can only provide a narrow range of data. Moreover, there are few AUVs and the unexplored kilometres of ocean are many. The work of one European project, however, has the potential to dramatically increase the range and functionality of the world's AUV fleet using networking technologies and software.
