Postdoctoral Research Begins - Finding Sites

In the last week I have begun to work on my new postdoctoral research that focuses on how elevated turbidity levels can impact on exotic and native fish populations. This work forms part of a grant that I was awarded earlier in the year, and will continue to fund me for the next few years.

I arrived back in New Zealand this last Saturday and have been looking at sites to initiate field sampling. I will be working in the Waikato River in New Zealand. The Waikato River is the longest river in New Zealand running for 425 km in the North Island. It has a strong turbidity gradient that I aim to sample fish biodiversity along. Some site searching managed to turn up some turbid sites and some clear water sites. Here are some pics.

Sustainable Seafood

We are told time and again that we need to eat more seafood for a healthier diet. But how does this work when, globally, fish populations are in massive decline. Barton Seaver, sustainable seafood advocate and chef, gives his opinion in this 10 min video. Enjoy.

Should Fishing Be Protected?


So here is an interesting topic, which is bound to produce anger and anxieties on both sides of the fence. Today (Nov. 2) voters in Arizona, Arkansas, South Carolina, and Tennessee are going to the polls to decide whether hunting and fishing should be protected under each states constitution. When something is protected then it becomes very difficult for the courts to take that right away from you. So by doing this today it is ensuring that fishermen will have a right to catch fish for future generations. 

This has largely come about because recreational fishermen have become fearful of recent attacks by PETA (People For The Ethical Treatment Of Animals) who have campaigns against fishing - viewing it as cruel and unnecessary. PETA are nothing to be ignored, and honestly, if I were a fishermen I would be concerned too. By implementing these laws they protect their 'right' to fish. I think that both hunting and fishing should be allowed if it is undertaken responsibly. 


The problem is that PETA have made this into an animal cruelty issue when it should be a conservation issue. With these laws in place it would be very difficult for any government agency to reduce fishing if this action was resulting in a significant reduction in fish populations. It is already difficult for these agencies to enforce current regulations to stop recreational fishers from overfishing, and the last thing we need is to make this job even harder! For example, what if fish stocks were depleted in an area and the government agency wanted to stop fishing in that area to help them recover? Fishermen might argue that it is their constitutional right to fish there. Recreational fishermen tend to be very resistant, maybe even a bit touchy, when it comes to other people telling them what they can do with their fish. This can sometimes be despite mounting evidence that that fish stock may be in trouble. One only needs to remember the arguments commercial fishermen made when the scientists told them the cod stocks were running out. 

In the end people need to remember that we all want the same thing. I want to be able to go diving and see fish in their natural environment. Fishermen want to be able to go out and fish. The emphasis should not be on protecting the right of the fishermen, or even PETA's animal cruelty agenda, the focus should be on protecting fish stocks so we can all enjoy them.

X Fish


Kansas has agreed to designate Xiphactinus or X-fish the states official fossil. This fish was found within a Kansas prairie, which was once covered by water. This was after a petition with over 3000 names on it.

Hmmmm fossils in Kansas how will the creationists feel about that?

Cave Angelfish

Member of the family Balitoridae (Loaches) belonging to the order Cypriniformes (Carps). This group of fish is known for their non-visual senses and its a good thing since this fish is perhaps one of the most specialised species on earth inhabiting only waterfalls within caves in Thailand. This fish has no eyes and lives out its entire life within the cave. They hang on to rock with microscopic hooks on their flattened fins. Their diet is bacteria. They were filmed for the first time for the BBC documentary Planet Earth.

Would You Eat Fish From The Gulf Of Mexico?

BP's chief operating officer has said that he would eat fish from the Gulf of Mexico and would let his family eat it, too. This from the Associated Press. His reasoning is that the USA governmental bodies wouldn't allow unsafe fish to be eaten. I find this interesting after all that has gone down in the meat packing industry. But my main question I want to ask is......

Would you?
