Wastewater reuse supports paddlefish project
A pilot project in Kentucky that uses wastewater effluent and decommissioned tanks at a water treatment plant has cultured over 70,000 phase II paddlefish.
Vibrio contamination in raw oysters controlled by post-harvest treatments
The levels of harmful Vibrio bacteria – a pathogen that multiplies at higher temperatures – in raw oysters depend largely on post-harvest handling.
GIFT tilapia show greater FCR, growth potential than red tilapia
In a study of the effects of interaction between genotype and dietary protein levels on fish performance, GIFT tilapia had greater growth than red hybrids fed diets with equal or higher protein levels.
GOAL 2018: PechaKucha, featuring Matthew Thompson
Matthew Thompson of the Anderson Cabot Center for Ocean Life at New England Aquarium speaks as part of the "Thoughts on the Future of Aquaculture in the PechaKucha Style" at GOAL 2018.
Cobia aquaculture expanding in Americas, Caribbean
A marine fish species with excellent characteristics for commercial aquaculture, cobia is receiving much attention in Latin American and Caribbean countries.
Marine, brackishwater finfish culture in Indonesia
Despite the impacts of the December 2004 tsunami, aquaculture in Aceh, Indonesia, is recovering with support from Indonesian and international agencies.
Airlifts combine pumping, water treatment in recirculation systems
Using the buoyancy of the entrained air bubbles to lift the water, airlifts are more energy-efficient and provide more aeration, carbon dioxide removal and foam fractionation for dissolved solids removal than centrifugal pump systems.
Snail control in fish ponds
The freshwater drum is a proposed snail-control vector in catfish ponds. In tank studies the drum showed high survival and reduced snail populations.
SCP comparable to hydrogen peroxide as catfish egg disinfectant
In studies, sodium carbonate peroxyhydrate proved an effective alternative to formalin and hydrogen peroxide as a treatment for controlling fungal infections of catfish eggs and improving hatch rates.
Replacing dietary fish oil with palm oil in Nile tilapia
Authors investigated the effects of replacing dietary fish oil with palm oil in juvenile Nile tilapia, and demonstrated that growth and feed utilization were not compromised when palm oil was used either partially or totally.
Genetic improvement in Brazil
Breeding efforts at Aquatec Genearch Aquacultura in Brazil have centered on specific pathogen-free white shrimp lines imported from the United States.
Collective marketing may help small-scale fish farmers grow in Africa
In research on collective marketing involving 32 small-scale fish farmers in Cameroon, 12 made a profit, which sparked further local interest in the concept.
UNC-Wilmington conducts research on black sea bass
Studies at UNC-Wilmington found that growth and survival of black sea bass larvae were improved through supplementation of DHA and ARA in live feed.
Walking catfish production in Thailand
The excellent culture characteristics of hybrid walking catfish have made them the dominant culture type in Thailand.
Little fish in a big pond: Minnowtech aims to give fresh vision to shrimp inventory
Because shrimp farmers lack accurate in-pond inventory, startup Minnowtech is on the verge of offering a data-driven solution. It’s got something to do with jellyfish.
Octopus aquaculture – unethical or the next Big Thing?
A team of scientists recently made the case against octopus farming, but others believe in its potential. What lies behind this emerging aquaculture opportunity?
Pilot-scale recirculating rotifer culture system uses condensed microalgae
Intensive rotifer culture systems can significantly reduce the space and labor requirements for the production of rotifers in marine finfish hatcheries.
Fingerling production still bottleneck for cobia culture
Production of cobia (Rachycentron canadum) is growing rapidly in Asia, yet fingerling production predominantly occurs in extensive pond environments.
