By David Cox, the Fish Vet Group - Fungi are ubiquitous throughout nature and if left untreated many fungal infections in farmed and pet fish can be life threatening.
However Thai shrimp production has been on the decline in recent years. If most of the decline (10%) in 2011 was related to natural disasters like oods, the main culprit in 2012 has been the EMS/AHPND disease outbreak. is new disease resulted in massive mortal…
This study by Yukinori Mukai, International Islamic University Malaysia, and Leong Seng Lim, University Malaysia Sabah, examined the retinomotor responses and prey ingestion rates of 10-, 15-, 20- and 30-day-old Asian seabass Lates calcarifer under different l…
Positioning of sea cages at sites with high water current velocities expose the fish to a largely unknown environmental challenge. In this study David Johansson et al, Institute of Marine Research, Norway, observed the swimming behaviour of Atlantic salmon (Sa…
New findings published by researchers at the New York University Polytechnic School of Engineering are helping to unravel the complex interplay between alcohol and social behavior and may lead to new therapies for mitigating the negative impacts of alcohol use…
Several indices were examined to assess the physical condition of wrasse stocked on Atlantic salmon, Salmo salar, farms as cleaner fish, and included examination of eye condition, snout erosion, skin hemorrhaging, and erosion and splitting of dorsal, pectoral,…
Introduction
Discussion of the current shrimp disease crisis focuses on the microbiology of pathogens and the regulations needed to limit their spread locally and across national boundaries (FAO 2008; Jones 2012; Lightner 2012; Reantaso 2012). In this study I …

One of the most difficult problems in Atlantic salmon aquaculture has been to control sea lice (Lepeophtheirus salmonis and Caligus elongatus in the Northern Hemisphere and Caligus rogercresseyi in Chile), which may cause serious harm to aquaculture reared fis…
By Pete Southgate, the Fish Vet Group - When keeping ornamental fish as pets, it is just as important to give full consideration to their welfare as with any other pet. The term ornamental fish in itself is an unfortunate one and a more acceptable term may be …
A significant part of the Philippine production is achieved semi-intensively, or even intensively, which creates a demand for supplemental feed. Optimizing of the feeding and nutrition of milkfish is therefore of great interest. Dietary potassium diformate (KD…
Increases in atmospheric carbon dioxide drive accompanying changes in the marine carbonate system as carbon dioxide enters seawater and alters ocean pH. As such changes do not occur in isolation, and other environmental factors have the potential to modulate t…
Collection and Submission of Samples for Fish-Kill Investigation and Toxic-Substance Analysis - By Robert A. Pierce, Extension Fish and Wildlife Specialist; Thomas W. May, National Biological Survey, National Fisheries Contaminant Research Center and V. Charle…
Taurine is not considered an essential amino acid for fish, but many studies indicated that it is conditionally essential, especially if fish are fed plant protein-based diets. In response to these studies, Abdel-Fattah M. El-Sayed, Alexandria University, Egyp…
