A probiotic that increases survival rate in Eastern oyster (Crassostrea virginica) larvae by as much as 35 percent could be commercially available by 2020.
A recent study from the Department of Wildlife and Fisheries Sciences at Texas A&M University in College Station, Texas, U.S.A., found taste is essential to feed efficiency and growth when using plant-based protein feeds.
African researchers are pushing for inclusion of moringa leaf powder in fishmeal for the Nile tilapia (Oreochromis niloticus), following the results of their study. The flesh of fry fed solely with the leaf powder showed higher protein content compared to those fed with fishmeal.
Given the unique nature of each RAS facility, maintaining a catalog of Standard Operating Procedures (SOPs) specific to your site is helpful. SOPs describe how essential routine tasks at the facility should be performed to meet quality standards. Up-to-date SOPs are a useful tool for training new hires and are a guide for continuity and quality assurance between staffing changes and work shifts.
The potential to breed salmon with enhanced resilience to gill infections and other health issues, such as sea lice, is a core part of a new £3.5 million (US$4.6 million) Scottish research and development initiative.
Salmonids lay their eggs in gravel redds for a reason, yet the use of rearing substrate in salmon and trout hatcheries, is not a common practice. Hatchery personnel at the Freshwater Fisheries Society of BC (FFSBC), on the west coast of Canada, have recently quantified the benefits of using substrate for early rearing of trout.  
New research out of Oregon, U.S.A, has found no negative impacts on wild steelhead (Oncorhynchus mykiss) populations from interactions with hatchery fish in the upper Clackamas River.
Nile tilapia reared in biofloc systems and fed with pizza by-product could provide economic benefits to farms, a study conducted in Brazil cited.
A recent study finds that brackish-water fish farmers in Malaysia earn more than freshwater fish farmers. 
In an effort to find ways to prevent hatchery fish from straying, Oregon State University researcher Maryam Kamran has been working with the Oregon Hatchery Research Center to study salmon responses to various scent stimuli. In recent years, Chinook salmon (Oncorhynchus tshawytscha) in the area are not homing as well as they once were, Kamran says.
Utilizing optimized culture conditions has cut the average larval development period of the common spider crab (Maja brachydactyla) by more than 50 percent.
The industry is under renewed pressure to embrace more sustainable practices to safeguard an increasingly fragile environment. Measures to prevent fouling of nets without the use of toxic chemicals are constantly being developed.
A study in Brazil on the “occurrence of compensatory growth, in view of enabling the storage of juveniles at densities in the intermediate culture phase” showed that juvenile scallops (Nodipecten nodosus) have ideal growth rates in a low-density environment.
Rigid artificial turf, smooth plastic or soft bottle brush?
According to a peer review conducted by Fisheries and Oceans Canada, farmed salmon that carry and transfer the deadly Piscine Orthoreovirus (PRV) pose a low risk to wild Fraser River sockeye salmon in British Columbia.
