U.S. white shrimp are caught from August to November, and are usually available frozen as tail meat year-round. White shrimp is low in saturated fat and is a very good source of selenium and vitamin B12. Random tests are recommended to ensure that the shrimp that arrives is actually what was ordered.
Buyer Beware: Most shrimp is treated with the preservative sodium tripolyphosphate, but too much will make the shrimp appear translucent and give them a soapy feel. Buyers recommend asking for specific moisture content since processors sometimes undercook the shrimp to increase weight. Many fishermen prevent black spots on shells by using bisodium sulfates but overuse causes pitting on the shells.
White shrimp are highly fecund and can grow fairly quickly, allowing them to rebound quickly from unfavorable environmental conditions such as extreme cold weather. The population levels of white shrimp, which are particularly abundant in the Gulf of Mexico, are high and overfishing is not occurring, according to the National Marine Fisheries Service. They thrive in marshy, estuary-filled areas and are found higher in the water column than brown and pink shrimp.
Habitat impacts ( Wild)
Although fishermen use a variety of gear to catch white shrimp, the otter trawl is the most common. Since this gear is meant to maximize contact with the ocean bottom, it can harm marine organisms, damage the seafloor, disturb sediment, lower sea grass production, and cause an increase in algal blooms. Trawling also occurs in the same areas annually. Overall, the effects of trawling on the habitat are a moderate concern in this fishery.
Thousands of sea turtles are caught in shrimp trawls annually in the U.S. Atlantic and Gulf of Mexico. Since shrimping trawlers interact with sea turtles so much, U.S. shrimpers are required to have turtle extruder devices (TEDs). Compliance varies but is good in the southeast Atlantic coast shrimp fishery, according to the Environmental Defense Fund. The white shrimp fishery also contributes to mortality in Gulf of Mexico red snapper, which has been overfished for decades. Other species of concern include endangered smalltooth sawfish, endangered Atlantic sturgeon and overfished blacknosed shark.
Commercial shrimp fisheries are working on reducing bycatch impact through time-area closures and bycatch reduction devices, according to the U.S. National Marine Fisheries Service. The white shrimp fishery abundance is monitored by the NMFS. Despite management efforts in the shrimp fisheries, bycatch continues to greatly outweigh shrimp landings. Bycatch reduction methods depend on compliance, which is not at 100%.
