American lobster population, habitat preferences shifting, study finds

American lobsters along Maine’s coast have relocated to new habitats, while the population simultaneously shrunk in abundance and grew older, according to a new study by University of Maine researchers. For decades, the vast majority of adult lobsters resided in majority of adult lobsters. This knowledge helped inform longtime conservation efforts and regulations within the more than $740 million fishery. A team of UMaine scientists, however, found that from 1995-2021, occupancy of boulder habitats dropped 60%. Meanwhile, the number of lobsters residing in sediment or featureless ledge habitats, both of which have little to no geological features to use as shelters, increased 633% and 280%, respectively. Lobster population density across all types of habitats declined too, meaning they are fewer in number and their populations are more spread out. more, >>CXLICK TO READ<< 16:20

New cod migration data: Study co-author George Rose says northern cod have returned to historical migration patterns

The co-author of a new study in the Canadian Journal of Fisheries and Aquatic Sciences says Newfoundland and Labrador’s northern cod have returned to their historical migration patterns with potentially major implications for the provincial fishery. George Rose, co-author of the study with the Institute for the Oceans and Fisheries at the University of British Columbia, says the new data suggests a return to the commercial cod fishery one day is possible. The study followed 90 large northern cod equipped with tags that transmitted data to satellites for over a year. Researchers found northern cod have re-established historical migration patterns and confirmed capelin can influence their timing and duration in inshore waters. more, >>CLICK TO READ<< 06:42
