New Aspect in Cartilage Growth “The Invasive Interstitial Type”
Growth of hyaline cartilage is achieved either by chondrocyte division “interstitial type of growth” or by perichondrial cell differentiation of mesenchymal cells to differentiated chondrocytes which deposit successive circumferential layers of cartilage...
Examining Gelatinized and Non-gelatinized Corn Starch Based Diets in Rohu Carp
Labeo rohita may be able to utilize the non-gelatinized corn starch based diet more efficiently and being economical it spares the protein based cost effective feed, according to research by Mahwish Qamer et al, University Faisalabad, Pakistan....
Probiotics for Health Management in Aquaculture
Aquatic animals have a much closer relationship to their external environment than terrestrial animals and are thus more susceptible to pathogens in their environment....
Use Of Ulva Lactuca Studied In White Shrimp Diets
Research conducted by Susan Laramore et al, Harbor Branch Oceanographic Institute at Florida Atlantic University, studied whether fresh U. lactuca harvested weekly from a land-based integrated multi-trophic aquaculture system could be utilized as a...
AQUAPLAN 2014-2019 - Australia's National Strategic Plan for Aquatic Animal Health
AQUAPLAN 2014–2019 is Australia’s third national strategic plan for aquatic animal health. It outlines the priorities to strengthen Australia’s arrangements for managing aquatic animal health, and to support sustainability, productivity, and market...
Persistence of Tetracapsuloides Bryosalmonae (Myxozoa) in Chronically Infected Brown Trout
Proliferative kidney disease is a widespread disease of farmed and wild salmonid populations in Europe and North America, caused by the myxozoan parasite Tetracapsuloides bryosalmonae. Ahmed Abd-Elfattah et al, University of Veterinary Medicine, Austria,...
Chronic Exposure to High Nitrate Concentration Reduces Growth and Affects Health of Juvenile Nile Tilapia in RAS
Due to nitrate accumulation during nitrification and low water-exchange rates in recirculating aquaculture systems (RAS), nitrate levels can build up. Hendrik Monsees has therefore investigated the effect that exposose to high nitrate concentration has...
European Seabass Perform Better in Cages With a Big Volume
Although the effects of fish density on the performance of fish have been widely studied, there has been little work done into the effect of cage size on seabass performance, said Athanasios Samaras speaking at Aquaculture Europe 2014, writes Lucy Towers,...
Effects of Temperature, Digestion on the Swimming Performance of Juvenile Chinese Bream
To test whether digestion affected swimming performance in an active forager and whether the possible effects varied with temperature, Jing Peng et al, Chongqing Normal University, investigated the critical swimming speed (Ucrit) and the resting and active...
A Nutritional Additive Increases Survival and Reduces Parasitism in Nile Tilapia During Masculinisation
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 Pádua, Aquivet Saúde Aquática,...
Effects of Salmon Lice Infection on the Behaviour of Sea Trout in the Marine Phase
Salmon lice Lepeophtheirus salmonis Krøyer may affect survival and growth of anadromous salmonids through physiological stress and/or behavioural changes. Using acoustic telemetry tracking, Karl Øystein Gjelland et al, Norwegian Institute for Nature...
First Report of Winter Epizootic of Salmon Lice on Sea Trout in Norway
Knut Wiik Vollset and Bjørn Torgeir Barlaup, Uni Research - Environment, LFI, Norway, report on the first observation of a winter epizootic of salmon lice Lepeophtheirus salmonis Krøyer on sea trout Salmo trutta Linnaeus in a Norwegian fjord with intensive salmon...
Detection and Surveillance of Viral Hemorrhagic Septicemia Virus Using Real-time RT-PCR. Part Two - Diagnostic Evaluation of Two Protocols
Two real-time reverse transcription polymerase chain reaction (rRT-PCR) assays under consideration for deployment to multiple testing laboratories across the USA were evaluated for diagnostic sensitivity and specificity on tissue homogenates obtained...
Health Challenges in Tilapia Culture in Brazil
In line with the level of investment, changes in concepts with regards to sanitary and health management can ensure stable and efficiency in production. Risk reduction from diseases requires continuous diagnosis of pathogens, adoption of biosecurity measures...
Detection, Surveillance of Viral Hemorrhagic Septicemia Virus Using Real-time RT-PCR. Part One - Initial Comparison of Four Protocols
Eight laboratories worked collectively to evaluate 4 real-time RT-PCR (rRT-PCR) protocols targeting viral hemorrhagic septicemia virus (VHSV) being considered for deployment to a USA laboratory testing network, write Janet V. Warg et al, National Veterinary...
