Gene Silencing Technology Alters Sex Of Prawns

Society for Experimental Biology Israeli scientists have developed a novel method for generating single-sex populations of prawns. This could be used to boost the productivity of aquaculture farms and even as a biocontrol measure against invasive species and pests. Male sexual differentiation in crustaceans is regulated by the androgenic gland. It is thought that this overrides a default program of female differentiation, allowing male features to develop. This comes from the...

Invasion Of The Oversized Crustaceans! Asian Tiger Shrimp Invade The US

Giant cannibal shrimp are invading the coasts of America en masse -- and while it sounds like the work of a mad scientist in one of those cheesy, low-budget, black-and-white 1950s science-fiction movies, the danger (or rather, lack thereof) is all too real. U.S. Geological Survey (USGS) and National Oceanic and Atmospheric Administration (NOAA) researchers have discovered that there were more than 10 times as many sightings of Asian tiger shrimp, which can grow to be more than a foot long...

Invading Species Threaten Texas Gulf Coast

The Asian Tiger Prawn, an invasive species in the Gulf of Mexico that can grow nearly a foot long and threatens native wild stocks, has been found on the Texas coast. The tiger prawns, native to the western Pacific, have been spreading along the Gulf Coast since 2006 and their numbers have increased this year. Shrimpers pulled the first one from Texas waters in June. So far shrimpers harvested three in Aransas Bay, one from Sabine Lake at the Louisiana Border and one from open waters about...

The National Oceanographic and Atmospheric Administration (NOAA) on Wednesday closed a section of the Gulf of Mexico to shrimping near the area where the massive oil spill earlier this year stemmed from as a precautionary move after a commercial fisherman found balls of tar in his shrimping net. NOAA said the closed area is about 4,200 square miles of Gulf federal waters off Louisiana, Mississippi and Alabama and affects royal red shrimping. The move was taken after a "commercial shrimper,...

Fish byproducts may be a new source of fish feed, thanks to research by U.S. Department of Agriculture (USDA)-funded scientists in Hawaii. Research scientist Dong-Fang Deng and her colleagues with the Oceanic Institute in Waimanalo, Hawaii, are collaborating with USDA food technologist Peter Bechtel to develop the new fish feeds. Bechtel is with the USDA Agricultural Research Service (ARS) Subarctic Agricultural Research Unit in Kodiak, Alaska. ARS is the USDA's principal intramural...

After 10 years of careful breeding and research, scientists have developed what could be the world's most perfect prawn. CSIRO scientists and the prawn industry have bred an improved Black Tiger prawn which is producing record yields in aquaculture farms and winning awards. So good are these prawns that they have won five gold medals at the Sydney Royal Easter Show in the past two years, including "ËœChampion of Show', the highest award possible. The scientists from CSIRO's Food...

Mexico's certification to export shrimp to the United States has been suspended because its trawls lack required protections for endangered sea turtles, the State Department said on Thursday. The ban on shrimp exports will come into effect beginning April 20, 2010, when the shrimping season ends. More than half of all Mexican shrimp is exported to the United States. The U.S. National Marine Fisheries Service determined that Mexico's turtle excluder devices were no longer up to code with...

Shrimp, a vital foundation of income for many developing countries, are becoming more susceptible to overfishing, the Food and Agriculture Organization (FAO) announced on Tuesday. Overfishing of shrimp can then corrupt ecologically significant seagrass beds and coastal regions, the UN agency wrote in the report, "The Global Study of Shrimp Fisheries." Shrimp is one of the most principal kinds of fishery product for many countries, creating total revenues of 10 billion dollars or 16...
