This study, by Ibrahim Diler et al, Suleyman Demirel University, Turkey, is the first trial to evaluate algae meal, Ulva rigida, as an inexpensive and locally available feed ingredient in the diet of common carp, Cyprinus carpio.

This report is the first in a series of articles highlighting the research results coming out of the NEMO Project, or its more formal name, Training network on protective immune modulation in warm water fish by feeding glucans. The project was awarded by the E…

Speaking at the Annual AVMA Convention in Chicago, USA, Jill Arnold, National Aquarium, Baltimore, provides an overview of clinical chemistry testing and a summary of the literature as a basis for future work to establish standard classification of fish leukoc…

Koi herpesvirus (KHV) is a highly contagious virus that causes significant morbidity and mortality in common carp (Cyprinus carpio) varieties (Hedrick et al. 2000, Haenen et al. 2004). Common carp is raised as a foodfish in many countries and has also been sel…

MicroRNAs (miRNAs) are an abundant class of endogenous small RNA molecules that downregulate gene expression at the posttranscriptional level. This study by Rune Andreassen, Oslo and Akershus University, et al, aims to identify and characterize miRNA genes in …

Mariculture of tropical sea cucumbers is promising, but the nursery rearing of juveniles is a bottleneck for farming and sea ranching. Steven W. Purcell and Natacha S. Agudo conducted four medium-scale experiments lasting 36 weeks, using thousands of cultured …

One of the most common problems of tropical and ornamental fishes are those caused by parasites. Fish parasites include protozoans, trematodes, cestodes, nematodes, acanthocephalans, crustaceans and arthropods, said Stephen A. Smith, Virginia Tech, speaking at…

The ability of species and populations to adapt to environmental change is the cornerstone of the emerging field of ecological genomics. Until recently, genome-wide studies of genetic adaptation in non-model organisms were not possible. Steve Smith, Flinders U…

In the present study, by Mads Kristiansen, University of Tomso, Norway, et al, the impact on gut microbiology and indigenous gut histology of Atlantic salmon (Salmo salar L.) was investigated following feeding of a control and a prebiotic (EWOS prebiosal) diet…

Dr Mark McMurtry's comparison of the two schools of aquaponics shows that the media-based, 'flood/drain' approach outperforms, by a wide margin, the hydroponic raft system. Dr McMurtry is widely acknowledged as the creator of the science of aquaponics when he …

Use of manufactured feeds in aquaculture in Bangladesh has grown rapidly over the last five years. More than 1 million tonnes of commercially formulated feeds and 0.3-0.4 million tonnes of farm-made feeds were produced in 2012, and sectoral growth is projected…

Aquaculture is the fastest growing food production system worldwide and is particularly important in bridging the gap between fish demand and supply in Nigeria. This study was carried out by F.O.A George et al, University of Agriculture, Nigeria, to determine …

Equipped with the zebrafish genome, researchers have designed a method to assay the function of each and every gene and to explore the effects genetic variation has on zebrafish. So far the team has generated one or more mutations in almost 40 per cent of all …
