Effect of Florfenicol on White Shrimp
Florfenicol (FLR) is a commonly used antibiotic for the treatment of bacterial diseases in white shrimp Litopenaeus vannamei. In this study, Xianyun Ren, Luqing Pan and Lin Wang, Ocean University of China, evaluated the tissue distribution and elimination,...
Small-Scale Aquaponic Food Production - Integrated Fish and Plant Farming
This FAO technical paper showcases current wisdom in aquaponics, focusing on small-scale production. The publication, written in a style designed to be digestible by a non-technical reader, is the product of practical experience with small-scale and commercial...
Alaska Fish Adapt to Climate Change by Following the Food
Not all species may suffer from climate change. A new analysis shows that Dolly Varden, a species of char common in southeast Alaska, adjust their migrations so they can keep feasting on a key food source - salmon eggs - even as shifts in climate altered...
Are Chemicals used to Maintain Mussel Farm Wood Rafts Potentially Toxic to Mussels?
At the Galician coast, mussels are cultured on vertical ropes attached to floating rafts, which are cleaned in situ with tars or waterproof paints. The present study, by F. San Juan et al, University of Vigo, Spain, analyses the composition and the toxic...
Hybrid Tilapia Outperform Pure-Breds In Seawater Study
With interest in culturing tilapia in marine habitats increasing, producers must obtain tilapia capable of growing well in seawater, writes Mohammad T. Ridha, Kuwait Institute for Scientific Research. Taken from the Global Aquaculture Advocate, a Global...
Manipulation of Farmed Atlantic Salmon Swimming Behaviour to Reduce Sea Lice
This paper describes a study in which environmental manipulation of salmon swimming depth was tested in an attempt to reduce farm infection of Atlantic salmon, Salmo salar by the salmon louse, Lepeophtheirus salmonis, write B. Frenzl et al, University...
Rapid Bacterial Colonisation of Low-Density Polyethylene Microplastics in Coastal Sediment Microcosms
Synthetic microplastics (?5-mm fragments) are emerging environmental contaminants that have been found to accumulate within coastal marine sediments worldwide. The ecological impacts and fate of microplastic debris are only beginning to be revealed, with...
Thermal Stunning Approach Works Best With Tilapia
In a study by Rachel Cristina Prehl Alves et al, Universidade de São Paulo, the authors evaluated the stunning effectiveness of thermonarcosis, carbon dioxide narcosis and electronarcosis by assessing the electrical brain activity of tilapia. Although...
Strategies to Spare Fish Oil in Aquafeeds While Maintaining the Nutritional Value of Rainbow Trout
The aquaculture industry is increasingly reliant upon industrially compounded aquafeeds, and the availability of cost-effective feedstuffs is a serious constraint to continued growth within the aquaculture sector, write Jesse T. Trushenski and Alexis...
High Survival Rate for Post-Smolt in Closed Facilties
Problems with lice and losses can be heavily reduced by placing farmed fish in closed systems until the fish reach a weight of one kilo. This has been shown by research conducted by scientists at Uni Research in Bergen, Norway....
Helping Salmon Cope with Stress of Transfer to Sea
Scientists are keen to sort farmed salmon and provide them with exercise right from the early stages of their growth, in order to equip them to deal with the stress of transfer to the sea....
How to Achieve Good Water Quality Management in Aquaculture
Water quality is the most important factor affecting fish health and performance in aquaculture production systems. Good water quality refers to what the fish wants and not what the farmer thinks the fish wants. This means that farmers must understand...
Effects of Bamboo Charcoal Added Feed on Reduction of Ammonia and Growth of Pangasius
A 50-day feeding trial was conducted to determine the effects of dietary bamboo charcoal (BC) on ammonia (NH3-N) excretion and growth performances of Pangasius hypophthalmus, write M Sadiqul Islam et al, Bangladesh Agricultural University. ...
Hatchery Management and Tilapia Fingerling Production
This guide from Infonet-Biovision provides easy to follow information on hatchery management and tilapia fingerling production....
Marine Shrimp Biofloc Systems: Basic Management Practices
This publication summarizes basic management practices for the majority of farmers raising marine shrimp (Litopenaeus vannamei) in Indiana, US, based on the most current literature available, writes Robert Rode, Purdue University....
