Tridge summary

Researchers at the Texas A&M School of Veterinary Medicine & Biomedical Sciences have developed a sustainable fishing industry road map that uses population genomics to prevent overfishing and monitor genetic diversity. The five-step plan involves sequencing the genome for the species, identifying regional populations, measuring genetic variation, and using specific genetic markers to map out stock locations. This approach has been adopted by European fishery authorities and is expected to become standard practice in the industry. The researchers believe that population genomics can help assess and maintain biodiversity not just for fish, but for many species.

Researchers at the Texas A&M School of Veterinary Medicine & Biomedical Sciences (VMBS) have released a road map to help the global fishing industry become more sustainable. The five-step plan outlines how the fishing industry can use population genomics—large-scale comparisons of a species' DNA—to prevent overfishing.The road map, recently published in the Annual Review of Animal Biosciences, can also be used to monitor the genetic diversity of any species—not just fish."Fishing is a very important component of our food security" said Dr. Leif Andersson, a professor in the VMBS' Department of Veterinary Integrative Biosciences. "The marine food chain is also very interconnected, so having low numbers of one type of fish can be detrimental for many other species."Unfortunately, over a third of the world's fish populations are in decline due to factors like overfishing and global warming," he said. "Our road map can help the fishing industry keep a closer eye on fish populations so ...
