    Nemertine collection at Aina’s house. Everything went well and we collected many Lineus viridis. Let’s see when they begin to lay egg cases.

    Collection of Membranipora 

    Yesterday I walked along Nordnes shore from Sars until the fish market looking for good collection spots for Membranipora. In the residence buildings next to USF it is possible to collect, but a harpoon is needed to reach the kelp. Otherwise you need to go into the water.

    The best spot is the Akvariet pier for Beffen line at Nykirken on Strandsiden. Easy to collect and full of colonies.

    Collected a bunch that looked orangy (cut in situ) and brought to the lab. Their stomach is full (color), but I don’t see many eggs. Keeping them in the dark and will try to spawn them on Wednesday.

    Today Andi, Aina, and me went on the boat to collect Novocrania anomala and Meara stichopi.

    N. anomala was collected by dredging rocky bottom and looking for specimens attached to rocks and shells. Rocks were kept in a large box with sea water and transferred to S4 tanks with flowing sea water at Sars.

    M. stichopi was also collected by dredging, but on mud bottom. Around 20 specimens were captured in a new spot: 60°14.946 N, 05°08.481 O

    Went collecting Membranipora with Anette at Hjellestad:

    The dock has a lot of kelp growing and the colonies of Membranipora and Electra were larger than last time, but still small (around 5 cm). We could find large colonies covering the whole surface of the algae. We also collected a jellyfish for muscle staining.

    Leaves were distributed in half-full buckets with water at 4 °C. I checked the colonies and most of the large ones had plenty of sperm inside the zooids, but not disc shaped eggs. There were smaller and rounded oocytes apparently. Buckets kept with a black plastic bag in the cold room.

    30/05/12

    Checked some colonies to see if they were alive; they were. Removed 1/3 of the water from the buckets and added more clean sea water.
