Formulated diets of astaxanthin and docosahexaenoic acid (DHA) promoted the best reproductive performance of purple mangrove crab Scylla tranquebarica, according to a study conducted in Malaysia.
Striking the right balance between darkness and light enhances the viability of hybrid catfish Heterobranchus bidorsalis x. Clarias gariepinus in its early life stage, according to a study conducted in Nigeria, where catfish is the leading aquaculture product.
The high mortality rate of green-lipped mussel (Perna canaliculus) spat shortly after they are seeded onto nursery ropes has been linked to feeding delivery.
NEW ZEALAND - New Zealand-based independent science organization Cawthron Institute opened its new Finfish Research Centre located at the Cawthron Aquaculture Park near Nelson, New Zealand on Tuesday.
Mixed feeding schedules, based on ad hoc circadian patterns, may be instrumental to optimize fish oil use in aquafeeds, maintain the targeted omega-3 (n-3) fatty acids in fish tissues and ultimately support the further growth of an environmentally sustainable and economically viable aquaculture industry.
U.S.-based biotechnology company White Dog Labs (WDL) has announced that independent testing by the Center for Aquaculture Technologies in Canada (CATC) has demonstrated the potential benefit of ProTyton, a single-cell protein (SCP), to shrimp farming. Initial studies demonstrated that inclusion of ProTyton into a CATC reference diet reduces mortality of whiteleg shrimp compared to a commercial diet when challenged by Vibrio parahaemolyticus (Vpa) — the aetiological agent of Acute Hepatopancreatic Necrosis Disease (AHPND), and commonly referred to as EMS.
Americans and Brits are increasingly saying "I'll take the fish," according to new research from U.S.-based food provider Cargill.
Recent developments in molecular techniques now allow researchers improved and more precise methods to edit the genome of livestock animals. Gene editing tools, such as CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) and TALENs (Transcription Activator-Like Effector Nucleases), are gaining attention around the globe for their ability to easily introduce or knock out specific target genes with the aim of enhancing certain animal traits.
A Tanzanian study identified protocols that induce ovulation of African catfish (Clarias gariepinus) broodstock and improve the quantity of egg hatchlings. This is a welcome development in a country where practically all C. gariepinus fry are sourced from the wild.
Hatchery techniques that work excellently for one bivalve specie larvae may not always have similar results on another.
One of the facts of many aquaculture facilities is that your fish are going to need to be treated for gill and external parasites or fungus. Be it chloramine T, Parasite S or Peroxaid, the frequency of treatments depends on many factors specific to each facility.
Feeding Atlantic salmon (Salmo salar) higher dietary phosphorous (P) throughout its freshwater life stage significantly reduces occurrence of vertebral malformations, according to a study conducted at the Institute of Aquaculture, University of Stirling in Scotland.
Production of steelhead smolts using natural origin broodstock can be optimized by sorting slower growing individuals several weeks after ponding and rearing them as age-2 smolts (S2), according to combined results from the hatchery and laboratory experiments of the U.S. National Oceanic and Atmospheric Administration’s Northwest Fisheries Science Center, Manchester Research Station.
Danish fish feed company BioMar is increasing it research capabilities with the opening of a new state-of-the-art marine fish larval trial unit. This addition expands BioMar's Aquaculture Technology Centre (ATC) Hirtshals facility in Denmark.
A study in Ecuador was able to demonstrate that hatchery production of rock oyster (Striostrea prismatica) spat is feasible, providing a basis for its large-scale propagation.
