Breeding & genetics

Eyeless Mexican cavefish show no metabolic circadian rhythm in either light and dark or constant dark conditions, according to a study published September 24, 2014 in the open-access journal PLOS ONE by Damian Moran from Lund University, Sweden, and colleagues…

Jan G. Davidsen and his graduate students are spies. They use listening stations and special tags they attach to their subjects to track their movements. They follow their subjects winter and summer, day and night.They are in pursuit of secrets and are relentl…

Fish are not silent creatures. Just like the terrestrial world, theres a veritable symphony of sound echoing under the sea.

Ectoparasites are key agents responsible for causing diseases in farmed fish. The Nile tilapia, in particular, has been shown to be susceptible to infestation by trichodinids and monogeneans, write Santiago Benites de Pdua, Aquivet Sade Aqutica, Roney Nogueira…

In an effort to understand the molecular basis of adaptation in vertebrates, BBSRC-funded researchers have sequenced the genomes and transcriptomes of five species of the African cichlid fish and uncovered a variety of features that enable the fish to thrive i…

Disease problems on shrimp farms may be partly driven by an interaction between management practices that cause inbreeding in small hatcheries and the amplification by inbreeding of susceptibility to disease and environmental stresses, writes Roger W. Doyle, P…

This review focuses on the recent advances in research on genetic relationships between Bonamia isolates, geographical distribution, susceptible host species, diagnostics, epizootiology, host parasite interactions, and disease resistance and control of this gl…

Bonamiasis, caused by Bonamia ostreae, was confirmed in native flat oysters Ostrea edulis L. in England in 1982. This paper reports on the controls and associated monitoring applied in the UK to prevent the spread of Bonamiasis and reports on the epidemiology …

This FAO report provides operators in the sector with up-to-date and complete information on the trade of eel. Statistical data from the last ten years has been examined, which represents a significant period for an economic evaluation of the sector and for as…

DNA vaccines encoding the viral G glycoprotein show the most successful protection capability against fish rhabdoviruses, write Beatriz Novoa et al, Instituto de Investigaciones Marinas (IIM), Spain.

Nicholas Robinson et al, Nofima, Norway, genotype full-sibling families using an Illumina iSelect array containing SNPs found in transcribed genes, in order to produce a genetic linkage map of the L. rohita genome and simultaneously scan the genome of challeng…
