Canadian fish in trouble

Two separate pieces in EurekAlert in the past couple of days point to something being decidedly rotten in the state of Canadian fisheries. First, evidence that parasitic sea lice from salmon farms are spreading to nearby wild populations and may wipe them out within a few years. ((Can anyone think of a similar thing happening with a crop and its wild relatives? I can’t.)) And the historic American eel fishery is also in trouble, possibly as a result of pollution in Lake Ontario. Bad luck, or something more?

A mighty wind

My recent post about lighting strikes in a coconut genebank was picked up by the excellent Coconut Google Group and generated some interesting responses. In particular, there’s a comment from Charles Clement of the National Institute of Amazonian Research in Manaus, Brazil recounting how a high-velocity wind blast — an Amazonian wind storm — took out a large chunk of his peach palm (Bactris gasipaes) genebank. Ex situ conservation in field genebanks can be a risky business indeed. The solutions are clear: more replications within collections, cleverly distributed in space; safety duplication of the entire collection somewhere else entirely (in vitro or as seeds as appropriate); and complementary conservation in situ. But that all costs money. I would say that most food crop accessions maintained in field genebanks around the world are unique. Take coconut. The Coconut Genetic Resources Database records 1416 accessions from 28 genebanks in 23 countries. More than 600 of them are represented by a single accession.
