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 …
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,…
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…

Introduction
Marine protected areas (MPAs) have received increasing attention as tools in fisheries management and conservation. However, examples of replicated experiments that sampled organismal density before and after establishment of MPAs at sites both in…
Aquaculture is replacing capture fisheries in supplying the world with dietary protein. Although disease is a major threat to aquaculture production, the underlying global epidemiological patterns are unknown. Tommy Leung, University of New England, and Amanda…
By David Cox, the Fish Vet Group - The Veterinary Health Plan (VHP) has been used for several years as part of good farming practice in many terrestrial animal production systems and forms the basis of several herd and flock health schemes.
By the Gulf States Marine Fisheries Commission - This report looks at the problem of White Spot Syndrome and gives an overview of its biology and recommendations to guard against it.
By Aqua-In-Tech - Diseases are due interaction between environments, the animal being reared (genetics, health, nutritional status, etc.) and the pathogen. In an ideal system these are in balance with the end result being minimal disease problems and increased…
