In a new study led by scientists at the University of Miami (UM) Rosensteel School of Marine and Atmospheric Sciences, more than 85% of the pigeons and snappers studied were over-exploited as a direct result of increased human demand for fish and shellfish. I found specific evidence that I was there.
The research team is a commercial and commercial in South Florida. Recreational fishing Use the length-based risk analysis (LBRA) framework.
They found that 3 out of 5 grouper species, all 8 snapper species, and 2 analyzed roars were below the 40% minimum spawning potential, which is the regulation required to maintain fish populations. I found that.
For black groupers, increasing the current minimum catch size from 24 inches (61 cm) to 44 inches (110 cm) will increase spawning populations to 40% and produce meaningful numbers of new fry. It will be large enough for you. It takes about 10 years for the population to recover to minimum sustainability and 22 years for reaching an equilibrium that enables sustainable fishing.
“The situation is similar to you Bank accountsGerald Alto, professor of environmental science and policy at UM Rosenstiel School, the lead author of the study, said: Not only to catch big fish, but also to spawn and replenish coral reefs. “
A study published in the journal, “Length-based risk analysis of management options for multiple US coral reef fisheries in southern Florida.” Fisheries researchProvides a blueprint for effectively balancing fishery production to reduce overfishing and protect these precious fish. Fish population Now and in the future.
