Arctic Tipping Points

We might not have gotten the bivalve species we looked for when fishing for clams last monday on the Jan Mayen but we certainly have been lucky to encounter ripe adults of various species. During the try-outs we managed to induce three species to spawn, absolutely necessary when you want to work with amounts of bivalve larvae of the same age.

The biggest problem has been to get females and males at the same time and our fertilisation rates have been disappointing ( a 30%) but we are learning. The clams are not in excellent conditions though after a full week in an aquarium so we will try to get ´fresh´ ones today.
