Key steps on how to become a fish veterinarian.
The key and first step, for any veterinarian interested in a discipline they are interested in and want to become more familiar with, is to get into the networks of colleagues that deal with the discipline.
For Aquatic Veterinary Medicine, I would recommend subscribing to AquaVetMed e-News (simply register in the free on-line Aquatic Veterinary Directory at www.AquaVetMed.info and select the e-News option).
I would also recommend joining the World Aquatic Veterinary Medical Association (www.WAVMA.org) that currently has members from over 40 countries on all continents. WAVMA member services and programs, including newsletters, discussion listservs, Continuing Education & Professional Development (CEPD) meetings and webinars, etc., bring together individuals and allow networking between experts and those just starting out.
To help veterinary students WAVMA is helping develop WAVMA Student Chapters at veterinary schools throughout the world. A new Aquatic Veterinary Practitioner Certification (Cert-AqVP) Program is being initiated in 2013. The Cert-AqVP Program is intended to help any veterinarian acquire “Day-1” competency in 9 core areas, that are necessary to practice aquatic veterinary medicine, but is generally not covered in most veterinary curricular.

Prevent fish diseases with TheFishVet’s Immuno-BOOSTER designed specially for fish.
You’ve heard about it…from the creator of nutritional supplements for sharks at AQWA (the Aquarium of Western Australia), TheFishVet’s immuno-BOOSTER mix is now available! Immunostimulants work! Check out some scientific articles at this link.
Dr Loh has been working with the compounding pharmacist to create an additive that you can mix with your fish food, to boost your fishes’ immune system. This is a great, natural way for preventing fish diseases and to help fishes recover more quickly from diseases. It’s perfect for changing weather conditions (autumn & spring), high temperatures (summer), transport (moving fish), grading/sorting and at any time your fish are exposed to stress.
This is TheFishVet’s immunoBOOSTER. It is a blend of powerful herbs and nutrients to help fish overcome infections. The recipe is based on the most current literature reviews.
Watch how TheFishVet’s immunoBOOSTER is prepared with the fish food of your choice on TheFishVet’s YouTube Channel.
Each capsule contains enough of the mix to add to 100g of fish food.
Place your orders now for a low price of $37.50 (+P&H) for 6 capsules.
Fish joke for Monday-itis: Noah’s ark.
Noah: he didn’t just build one ark but several arks for various parts of the animal kingdom. One for the fish turned into a split level job, or a multi-storey carp ark.
This one’s from Toni Erkinhaju as well.
What a mouthful! Male fish takes on the task of protecting its eggs… by cramming them into its mouth.

What’s this fish that’s got no red blood cells?
If you attended the Webinar given by my colleague, Dr Robert Jones The Aquarium Vet, he was discussing about fish blood and that some fish actually do not have red blood cells. I came across this article and thought if share it with you.

Breaking news! The mystery of the silent and deadly prawn killer, Early Mortality Syndrome, has been discovered!
This is what my friend, Loc Tran, from Vietnam is researching with Dr Lightner.

Subject: AquaVetMed e-News: Phage infected bacterium thought to be cause of shrimp EMS
May 2, 2013
Cause Of EMS Shrimp Disease Identified
After months of investigation by a research team led by Donald Lighter at the University of Arizona, the elusive pathogen causing early mortality syndrome (EMS), an emerging shrimp disease in Southeast Asia more technically known as acute hepatopancreatic necrosis syndrome (AHPNS), has been identified. The researchers found that EMS is caused by a bacterial agent, which is transmitted orally, colonizes the shrimp gastrointestinal tract and produces a toxin that causes tissue destruction and dysfunction of the shrimp digestive organ known as the hepatopancreas.
Lightner’s team identified the EMS/AHPNS pathogen as a unique strain of a relatively common bacterium, Vibrio parahaemolyticus, that is infected by a virus known as a phage, which causes it to release a potent toxin. A similar phenomenon occurs in the human disease cholera, where a phage makes the Vibrio cholerae bacterium capable of producing a toxin that causes cholera’s life-threatening diarrhea.
Research continues on the development of diagnostic tests for rapid detection of the EMS/AHPNS pathogen that will enable improved management of hatcheries and ponds, and help lead to a long-term solution for the disease. It will also enable a better evaluation of risks associated with importation of frozen shrimp or other products from countries affected by EMS.
Some countries have implemented policies that restrict the importation of frozen shrimp or other products from EMS-affected countries. Lightner said frozen shrimp likely pose a low risk for contamination of wild shrimp or the environment because EMS-infected shrimp are typically very small and do not enter international commerce. Also, his repeated attempts to transmit the disease using frozen tissue were unsuccessful.
Since EMS was first reported in China in 2009, it has spread to Vietnam, Malaysia and Thailand, and now causes annual losses more than U.S. $1 billion. EMS outbreaks typically occur within the first 30 days after stocking a newly prepared shrimp pond, and mortality can exceed 70%.
In an effort to learn from past epidemics and improve future policy, the World Bank and the Responsible Aquaculture Foundation, a charitable education and training organization founded by the Global Aquaculture Alliance, initiated a case study on EMS in Vietnam in July 2012. Its purpose was to investigate the introduction, transmission and impacts of EMS, and recommend management measures for the public and private sectors.
The study team included Lightner, who with University of Arizona co-workers recently identified the EMS/AHPNS pathogen. At a panel discussion on EMS at the Global Aquaculture Alliance’s GOAL 2012 meeting in October 2012, Lightner and Timothy Flegel speculated that the elusive nature of the disease might be explained by a bacteriophage.

| Abstract: | The present study provides new and practical information on the maturation of females seahorses Hippocampus guttulatus and Hippocampus hippocampus exposed to different temperatures (15°C constant, 15–18°C or 15–21°C) and photoperiods (10L:14D–16L:8D cycle or 10L:14D constant). Egg production (total eggs, clutch size and clutches per female) resulted notably reduced under both short photoperiods and low temperature, especially in H. guttulatus. Egg clutches were mainly released with temperatures above 16°C and increasing photoperiods beyond 14L:10D. The highest efficiency under a natural light regime was achieved at 21°C. Biometrics performed in H. guttulatus eggs showed that egg volume (VE) was not affected by temperature level but yolk volume (VY) and VY/VEratio in eggs of females exposed at 15°C were lower than in eggs released at 15–18°C and 15–21°C cycles. VE, VYand VY/VEin eggs were not correlated with the photoperiod regimes applied. The present study also provides the first results on shifting of maturation in H. guttulatus females submitted to photothermic manipulation of the environment (Treatment D — advanced and drastic change; Treatment A — advanced and accelerated change) or to natural conditions (Treatment N). The response of females to artificial environmental changes was successful and fast. First egg clutches in treatments D and A were released 11 (Treatment D) and 9 (Treatment A) weeks before than in females exposed to natural temperature and photoperiod regimes. However, the best overall results were achieved under natural regimes. In Treatment N, total eggs production and average egg clutch size (3690 and 461 eggs, respectively) were noticeable higher than in treatments D (3533 and 294 eggs, respectively) and A (150 and 1809 eggs, respectively). The study demonstrates the feasibility of shifting in female maturation of seahorses and its practical use in the artificial manipulation of the breeding season under captive conditions. | ||||||||||||||||
