Monitoring Fish Through Ultrasound

Welfare Technology & equipment +2 more

ARKANSAS, US - A researcher from the University of Arkansas at Pine Bluff is developing a new way to use ultrasound as a non-invasive menas to manage fish farm production.

According to Bobbie Crockett, writing for DeltaFarmPress, while an ultrasound exam is usually associated with pregnant human mothers, it can also be used to get an up-close look at fish. The pictures speak volumes and could benefit hybrid catfish producers.

The ultrasound technology allows researchers to look at eggs inside fish and can be used to determine gender if the fish is mature enough.

There are some aquaculture uses and some natural fisheries uses, researcher Neil Pugliese says, explaining that the tool could aid farmers fishing for a way to boost the breeding of male blue catfish and female channel catfish.

Theres an interest in hybrid catfish which have to be artificially spawned. One challenge is to use this tool on smaller and smaller fish to distinguish males and females.
