Study: Microplastic fiber pollution harms lobster larvae
A study published in the Marine Pollution Bulletin reports that the fibers affect the animals’ feeding and respiration, and they could even prevent some larvae from reaching adulthood. “Lobsters play a fundamental role in the Gulf of Maine ecosystem as well as the state’s economy, and it is important that we understand how pollutants impact their development.” Young lobsters grow to adulthood through four distinct developmental stages, and the researchers found that the physiology of each stage determined how the animals interacted with plastic fibers. The youngest lobsters didn’t consume them—but they were plagued by fibers accumulating under the shells that protect their gills. >click to read< 16:04
Narragansett Bay – Invasive Asian Crab Outcompeting Young Lobsters
Speculation about the cause of the decline of lobster populations in Narragansett Bay has focused on an increasing number of predatory fish eating young lobsters, warming waters stressing juveniles, and a disease on their shells that is exacerbated by increasing temperatures. A new study by a scientist at the University of North Carolina points to another contributing factor: Asian shore crabs.,,, Adult lobsters live in much deeper water than the shallow intertidal zone inhabited by Asian shore crabs, so the two species seldom interact. But some larval lobsters settle in the intertidal and subtidal zones, which they use as nursery habitat. Prior to the arrival of Asian shore crabs, it was an area that had fewer predators and an abundance of food. But now the young lobsters are finding themselves in competition with the crabs for food and shelter. >click to read<09:25
