The lab goes gigging to kick-off the start of Sheepshead sampling! Last Thursday, November 30th, Derek, Chris, and Tyler went gigging with one of the Fisheries and Mariculture Laboratory’s (FAML) own, Rene Lopez, owner of Seeing Red Charters. The goal of the sampling trip was to collect Sheepshead (Archosargus probatocephalus) that are under the legal size limit. Samples of small, young fish are needed to complete an age and growth study of the local fish population.
Sound produced by fish spawning aggregations permits the use of passive acoustic methods to identify the timing and location of spawning, but estimating fish abundance directly from sound levels has proved challenging. Here we show that models of measure fish sound production versus independently measured fish density can be generated to estimate abundance and biomass from sound levels at aggregations.
Our new data portal offers the best available data and information relevant to the biology, fisheries, monitoring and management of spawning aggregations in the Gulf of Mexico. The site was funded by the NOAA RESTORE Act Science Program.
Gulf Corvina look pretty ordinary—they’re a couple of feet long and silvery. Yet the sounds they make—when millions get together to spawn—are a kind of wonder of the natural world. It’s also why they are in danger. Learn more by listening to audio article on our research by Marc Airhart.

For marine fishes that form spawning aggregations, vulnerability to aggregation fishing is influenced by interactions between the spatio-temporal patterns of spawning and aspects of the fishery that determine fishing effort, catch, and catch rate in relation to spawning. In our new publication, we assess the vulnerability of the Barred Sand Bass (Paralabrax nebulifer) to a local commercial fishery in Punta Abreojos, Mexico.
