Researchers use DNA in seawater to monitor scallop reproduction

Researchers from the University of Maine and Bigelow Laboratory for Ocean Sciences have developed a method for studying the timing of scallop spawning by analyzing the environmental DNA found in water samples. The newly published study provides a tool for managing wild and farmed shellfish populations, and it demonstrates the promise of emerging eDNA approaches for monitoring the presence and activities of all marine life. >click to read< 08:37

The New England groundfish debacle (Part III): who or what is at fault? Nils E. Stolpe/FishNet

It took me a while to decide how to most accurately describe the situation that has been visited upon the New England fishing communities that are and since colonial times have been dependent on the groundfish fisheries.

NILS STOLPE: The New England groundfish debacle (Part IV): Is cutting back harvest really the answer?

While it’s a fact that’s hardly ever acknowledged, the assumption in fisheries management is that if the population of a stock of fish isn’t at some arbitrary level, it’s because of too much fishing.

It’s all about fishing, because fishing is all that the managers can control; it’s their Maslow’s Hammer.
