Fish Vetting Techniques and Practical Tips – instructional DVD: Fish Vetting Secrets revealed!

2014/01/21 at 08:30 | Posted in Veterinary Fish Medicine | 1 Comment

After attending a multitude of conferences and courses like Aquavet II and Seavet, reading up on the literature, and doing teaching at the university, it’s really hit home to me that: there is no better way to teach or learn, than to show, or be shown.

FISH VETTING TECHNIQUES & PRACTICAL TIPS takes a ‘how to’, hands-on approach to demonstrate veterinary skills employed in working as an aquatic veterinarian. The 105 minute DVD comprises veterinary procedures including taking skin mucus scrapes and gill biopsies, skin ulcer treatment, injecting fish, blood sampling, anaesthesia, surgery, necropsy, histology processing, videos of live microscopic fish pathogens and more… That’s right, I’m giving away all my secrets so that fish clients can have greater access to trained aquatic veterinarians no matter where they are in the world.

After watching this DVD, you can deal with fishes with confidence!

This DVD is ideal for fish veterinarians, aquarists, aquaculturalists, public aquaria, local fish shops and to have handy as a training resource in veterinary schools, laboratories, clinics and zoos. It is a comprehensive resource that incorporates aquatic medicine and pathology.

Fish Vetting Essentials.

2012/05/27 at 12:37 | Posted in Veterinary Fish Medicine | Leave a comment

The web can be a great resource but you may also find that it is full of contradictory information overload. Like you, I have found that reliable information on fish health, disease and medicine is difficult to come by and is at best, fragmented.

This is why I have published two essential books on aquatic veterinary medicine.

So if you’re serious about fish health, these are two indispensible texts on fish you must have at your fingertips!

Fish Health Professionals – Land the Catch of the Year!

Fish Vetting Essentials is a comprehensive resource that incorporates elements of fish keeping, clinical medicine and fish pathology in a readily digestible form.

Important information for diagnosticians in this book include:

  • how to interpret water quality
  • how to diagnose common fish diseases
  • how to medicate fish
  • how to treat fish diseases using drugs available in standard veterinary clinics.

What’s causing feminisation of fish in rivers and streams? What are the implications to human health?

2014/09/02 at 08:25 | Posted in Veterinary Fish Medicine | Leave a comment

Humans most vulnerable because one of the longest lived animals. Affect the early stage. Children most at risk because use a lot of plastics and they are closer to the ground and chew/eat things they really shouldn’t be eating.


Some of the more commonly studied effects of endocrine disrupting chemicals (EDCs) include:

  • Oestrogenic effects.
  • Anti-oestrogenic effects.
  • Androgenic effects.
  • Anti-androgenic effects.


What effects are already showing up in humans? According to Dr Handlinger at last week’s AAPSP Workshop, she reported that:

  • up to 40% of young men in some EU countries have low semen quality, reducing their ability to father children.
  • there is increased incidence of genital malformations such as cryptorchidism (non-descending testes) and hypospadias (penile malformations) in baby boys.
  • there has been an increase in adverse pregnancy outcomes such as pre-term birth and low birth weight.
  • neurobehavioural disorders associated with thyroid disruption affecting a high proportion of children in some countries.
  • increased global rates of endocrine-related cancers (e.g. breast cancer, endometrial, ovarian, prostate, testicular and thyroid cancers) in the last 40-50 years,
  • there are concerns that it is linked to increased prevalence of obesity and type 2 diabetes.


There is increasing evidence of adverse effects on wildlife. The 2013 EU response motions summarises the evidence:

  • “… significant… evidence that hormone-related disorders in wildlife including reproductive abnormalities, masulinisation of gastropods, feminisation of fish or decline of many mollusc populations in various parts of the word, are linked to the impact of chemicals with endocrine-disrupting properties”
  • Seal colonies in heavily polluted areas of the Baltic and North Seas – female reproductive pathologies and failure, bone damage – correlate with exposure to persistent organic pollutants (POPs), especially PCBs. Populations are recovering as PCB exposure decline.
  • Many amphibians are highly threatened with extinction – indications of an involvement of endocrine disruptors.
  • Especially in the UK, male fish have been widely affected by increased levels of egg yolk protein vitellogenin and by intersex. This is attributed to exposure to sewage effluents with contain oestrogenic and anti-androgenic chemicals.


If you notice, a lot of these problems are being encountered in mostly aquatic animals. Thus fish and amphibia are a major biological indicator, and tool. Globally, there has been a failure to adequately address the underlying environmental causes of trends in endocrine diseases and disorders. Close to 800 chemicals are known or suspected to be capable of interfering with hormone receptors, hormone synthesis or hormone conversion. However, only a small fraction of these chemicals have been investigated in tests capable of identifying overt endocrine effects in intact organisms. This is a major issue that has to be tackled by veterinarians, the medical profession and scientists, together.


From the EU paper, “endocrine disruptors are all around us in our everyday lives. They are present in food packaging, skin care products, cosmetics, building materials, electronic goods, furniture and floorings. Many products made of plastic in our homes and at our workplaces contain one or more types of chemicals which are suspected of having an endocrine-disrupting effect. As an individual consumer, it is impossible to know what substances are present in what products, particularly in the case of goods with no list of contents… endocrine disruptors are released from materials and products and accumulate, for example, in dust in our homes. Consequently small children, who crawl on the floor and also like putting things in their mouths, are at special risk of exposure.” (European Parliament 28.1.2013).

Here is how you can increase your case experience with fish vetting.

2014/08/28 at 08:00 | Posted in Veterinary Fish Medicine | Leave a comment

In the beginning, it was difficult for me to gain sufficient knowledge and experience with ornamental fish case loads being rather sparse.

Sure, I worked in a diagnostic laboratory; but I dealt mainly with salmon, trout, oyster, abalone and lobsters. I yearned to work with the prettier fishes.

One of my friends gave me this book as a present (one of the best gifts by far, thank you). In this book are 265 cases of fish health problems with diagnostic work ups and solutions to the ailments. This “Self-Assessment Colour Review of Ornamental Fish” by Dr Greg Lewbart is a most excellent publication. It quickly gave me the confidence that I have seen or read about the most common issues that are out there. I highly recommend it if you’re at all serous about being a fish veterinarian.

What’s more is that they’re publishing a second edition (yay!); and they’ve asked me to contribute some of my cases (yay x2!).

Keep a look out for the new edition when it’s ready!


Now THIS IS deep sea fishing!

Should you stop eating fish?

2014/08/26 at 08:05 | Posted in Veterinary Fish Medicine | Leave a comment

I was sent a link to this article. The writer does put out some great reasons for giving up eating fish, but I don’t believe that’s a good solution. I mean, if noone eats fish, and noone goes fishing, then noone is going to care about the fish and the seas and the environment. It’s only when we need to rely on the fish as food and we need to rely on the environment to be intact that we will truly care for them.

Have a read of the article and feel free to share your thoughts – link to article.

How unhealthy is the Swan River.

2014/08/21 at 07:45 | Posted in Veterinary Fish Medicine | Leave a comment

“Toxic algal blooms have left the Swan River “dead” below two metres and pathogens harmful to humans are being recorded above the safe swimming limit, according to new research…

Symptoms included low oxygen levels, high nutrient levels and fish deaths that exceeded the Swan River Trust’s target in four of the past 10 years.”
