Today, when one of the hauls came in, there seemed to be a kind of foam in the catch. It appeared to be more than 7 kilo's of whelk eggs. We catch whelk (and other gastropod) eggs quite frequently, but rarely so much. Ruben managed to pile the eggs in such a manner that we could weight the whole lot.
In 2014 schreven we een blog over paairijpe mannetjesroggen (http://beamtrawlsurvey.blogspot.com/2014/09/voortplantingreproduction-tijdens-deze.html).
In the same haul, we found a female starry ray (Raja radiata) that was about to lay an egg. While we were measuring the catch, she managed to lay the egg. Everything was put overboard after the measurements were done.
