A new model suggests options.<\/strong><\/p>\n\n\n\n

Research Need<\/em><\/strong><\/p>\n\n\n\n

The American red snapper (Lutjanus campechanus<\/em>) is a common offshore reef fish found in the South Atlantic and Gulf of Mexico. Fishers have long coveted this species due to its aggressive nature, colorful appearance, and status as top-notch table fare. However, these days red snapper seems to grab more attention for its controversial management.<\/p>\n\n\n\n

Despite continuing efforts to rebuild the South Atlantic red snapper stock, overfishing continues, leaving scientists, managers, and fishers at a crossroads. The stock’s recovery is critical not only for the health of reef ecosystems but also for the health of the fishing industry. Hence, there is a pressing need to investigate new management approaches.<\/p>\n\n\n\n

A group of researchers recently created a model to compare a suite of red snapper management approaches to one another and to assess whether they would end overfishing.<\/p>\n\n\n\n

What did they study?<\/em><\/strong><\/p>\n\n\n\n

The research team simulated 25 different management strategies, using varying combinations of measures: gear modifications, regulations that lower the mortality rate of discards (released fish), size limits, and regulatory approaches based on time and\/or area closures.<\/p>\n\n\n\n

The research team compared all outcomes based on how well each met four core management goals consistent with ending overfishing: decreasing dead discards, rebuilding population age structure, increasing adult spawning productivity, and increasing sustainable <\/em>landings.<\/p>\n\n\n\n

What did they find?<\/em><\/strong><\/p>\n\n\n\n

This study found that decreasing recreational fishing effort by placing limits on time and space was particularly successful in ending overfishing. Limited access to the multi-species fishery was most effective in reducing discards. <\/p>\n\n\n\n

Size limits, bag limits, and similar measures were not particularly effective in reducing discards. However, the use of descender devices, proved effective in lowering mortality. <\/p>\n\n\n\n

The study shows that fully retaining all species in the multi-species snapper grouper fishery may also be effective. Additionally, the researchers note that simulated management strategies may be paired together to meet goals.<\/p>\n\n\n\n

Anything else?<\/em><\/strong><\/p>\n\n\n\n

The American red snapper is one of dozens of species within the larger \u201csnapper grouper\u201d fishery. Many species overlap in habitat and are thus caught side-by-side, which leads to catch, release, and frequent mortality for out-of-season fish, whether it be red snapper or another species. <\/p>\n\n\n\n

Reducing the amount of recreational fishing activity may reduce discard mortality and accelerate stock recovery for red snapper and potentially other snapper grouper species. The authors highlight a permitting system as one possible approach. Tools like descender devices may also be effective means of improving survivorship.<\/p>\n\n\n\n

So what?<\/em> <\/strong><\/p>\n\n\n\n

Fisheries management sometimes holds off on decisions until more information is made available, delaying the implementation of new regulations. The present study shows a promising alternative that may quickly allow for more informed decisions. <\/p>\n\n\n\n

Modeling management scenarios, using a host of parameters, provides an objective approach to visualizing future successes. The widespread use of models may facilitate a wave of proactive management and ultimately help avoid overfishing altogether.<\/p>\n\n\n\n
