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.

Shark senses, and the development & testing of shark repellants – UWA. Part 2.

2014/10/01 at 08:00 | Posted in Veterinary Fish Medicine | Leave a comment

Following on from last week’s post, and just to recap, I was lucky enough to be invited to attend a seminar on ground breaking research into shark sensory perception and how they were developing and testing shark repellants. You’ll need to read the previous post to get a bit of background so we can understand how and why the following devices show promise.

 

Chemical repellants against sharks

Nathan spoke on the use of chemical repellants that would be detected by the olfactory system (sense of smell) of sharks. What they found was that sharks were repelled by the essense of dead shark, special slime produced by the sole fish and sea cucumber and also, some common household detergents. Good news? Yes, in a way. But testing showed that these were impractical because diffusion of the chemical stimuli is too slow, and in the field where there is water current, these smells would not stay put.

 

Accoustic shark deterrents

It is known that sharks can hear low frequency sounds and are attracted to them. Research showed that they do not like loud sounds. But with time, they become habituated to it (used to it) and so they will return. So, loud sounds don’t really work in the long term. They were planning on trialling whale sounds. Not the relaxation ones people use for meditation, but ones from the predatory killer whales (OK, before you kick me, I know they are not considered true whales). They did talk about the theory of neophobia (fear of new things). Here they tried electronic sounds like from the Star Wars’ R2D2 which seemed to repel sharks. What also seemed to work was songs from ACDC! Sharks are no fans of the heavy metal music (frankly, I don’t blame them).

Visual protection against sharks

Sharks are attracted to yellow and silver, and they tend to investigate objects sporting these colours. They have found that low contrast material work as camouflage. For divers, they trialled 3 different shades of blue with patterns to break up the silhouette and they found it worked. They also trialed novel, unpleasant visual stimuli like very bright flashing lights which seemed to work. There is also the theory of biomimicry, having contrasting black and white stripes to imitate venemous sea snakes.

 

Electric deterrent system

Some products are being marketed as “shark shields”. These are electric deterrent systems and they do appear to be effective. There is promise for it to be used to protect swimming areas, and as a personal-based device. But more research needs to be done to know what are their limitations. Does it matter what species of shark, shark size, will it work with multiple sharks and will sharks become habituated?

 

But the most simple, and most promising thing researchers have found is….

Shark senses, and the development & testing of shark repellants – UWA. Part 1.

2014/09/26 at 07:50 | Posted in Veterinary Fish Medicine | Leave a comment

Last Thursday, I attended a very good lecture on this topic at the University of Western Australia. Each of 3 lecturers took it in turns to present their unique findings: Prof. Shaun Collin, Assoc. Prof. Nathan Hart and Dr Ryan Kempster, all from the School of Animal Biology.

So what have we learnt?

 

The presentation started with describing their findings of the shark senses. Being living animals, it is not surprising that they have the 5 senses: sight, hearing, smell, taste, touch. These will be explained below.

 

Sight

They have found that sharks are monochromats, having peaks in receptors for the green-yellow wavelengths (with a secondary low peak at purple). Practically, this means they are somewhat “colour-blind”. Characteristics of colour-blind animals is that they are very good at detecting contrasts. They’ve found the greatest density of receptors in their eyes lie in the posterior-ventral part of the retina and this means that their line of best site is diagonally above, and in front of them. However, their visual acuity is only moderate which means they have to get close to see more clearly.

 

Hearing

On sound, sharks do have ears. The opening to the ear is in the dorsal surface (top) of the head, a slight distance behind the eye. It detects vibrations and hydrodynamic sounds (e.g. waves, splashing, eating, bubbles). They have good directional hearing, meaning they can tell where sound is coming from. Of the 10 shark species studied, they’ve found they can hear low frequency sounds, in the range of 10-800 Hz (cf humans 20-20,000 Hz).

 

Smell

Sharks have nostrils and they point downwards. They have folded skin to increase the surface area, making them able to detect as little as 1 drop of blood in a olympic-size swimming pool. This said, the olfactory bulbs in the brain of different elasmobranchs differ in size, so we can’t quite make sweeping generalisations.

 

Taste

Sharks have no external taste buds. Their taste buds are located in the oropharynx, basihyal (tongue) and gill arches. The highest concentration of taste buds are behind their teeth. This explains why they need to bite, or to mouth at things, in order to taste it.

 

Touch

I think I was late in to the lecture, and might have missed this section, or maybe they didn’t cover it. But if you’re reading this, and you were there, please do elaborate in the comments section. Thank you.

 

So, sharks have all the 5 senses that we have. But they have a couple more! Firstly, like all fishes, they have a “lateral line system“. These are little pits along the length of the body, each pit contains hairy cells and the pits are connected to adjacent pits by a channel. The lateral line system detects water motion and low frequency sounds (20-200 Hz). It is used for detecting obstacles.

 

The second special sense they have is called the “ampullae of Lorenzini“. These a small pits around the area of their snout and within the pits is a gel-like substance that helps conduct electrical currents from the environment to the electroreceptors within. These are so sensitive that they can detect electrical currents as low as 1 billionth of a volt! They use this to detect prey since all fishes produce small electric fields. Thus, electrical stimuli actually attract sharks to check things out. The abundance of these ampullae vary between species. A Port Jackson shark has only 200 pits, making them less adept at locating electrical stimuli, whereas the hammerhead shark as as many as 3000 pits, making them finely tuned. The great white shark has 800 and the shovelnose ray has 1200.

 

So now we know about their 7 special senses, how do we use this knowledge to our advantage? How do we create safer beaches for swimming? How do we create personal protective devices for divers?

 

Stay tuned to find out in my post next week.

This is a common guilt-trip question every non-enthusiasts puts to us. My argument is that it’s one of the healthiest “static” hobbies around.

Anyway, I came across a FB post by Boronia Aquarium that led me to find this humorous article on how you can decrease your power consumption.

3 simple steps to treat koi ulcers.

2014/09/24 at 15:43 | Posted in Veterinary Fish Medicine | Leave a comment

Recently I gave a presentation at the koi club about the myriad reasons for koi developing skin ulcers. It’s an opportune time since they may get scrapes from the mating acts, damaged from shifting, predator attack, etc.

For uncomplicated ulcers, I’d like to point you to a video I uploaded on on how to treat fish ulcers.

“Now it seems the fish are surprisingly picky about when they ask for that help – and which eels to approach. The trout show a level of discrimination in when to collaborate, and with whom, that was thought to be unique to the likes of humans and chimpanzees.”

Diagnosing fish diseases using air-dried, unstained slides.

2014/09/23 at 07:27 | Posted in Veterinary Fish Medicine | Leave a comment

Air dried smears are not exactly the best sample for making a diagnosis, but it can work, especially if there are numerous external parasites and that the smears are prepared correctly.

It’s ideal in situations where the remote site is without a microscope, or someone who knows how to use one, or knows what to look for. The slides can be prepared easily and sent by post to your nearest fish veterinarian to make a diagnosis.

To prepare the smears, simply follow the steps as per taking gill biopsies and skin mucus scrapes, and then smear these onto the glass slide. Do not add any water. Wave the slides in the air until dry.

Check out how the slides are examined and what you can see: http://youtu.be/ghLjcVJgyPA

For added diagnostic advantage, the commonly used Diff Quik stain can be applied to the smears.
