- A diver in Australia has captured the first photos of a wild fish using a tool. The shots show a blackspot tuskfish - Choerodon schoenleinii - holding a clam in its mouth and hitting it against a rock to get at the bivalve inside. See the images here. Have any of you aquaculturists seen fish behaving is a similar way? Let us know.
- We think of fish as food first and foremost but aquatic species have many applications, including healthcare. The first issue of International Aquafeed in 2013 will contain an feature on diets for zebrafish, which are routinely bred for health purposes. With this in mind, this article on the LSU AgCenter Aquaculture Research Station, USA caught my attention. Researcher Terry Tiersch has two National Institutes of Health grants of over $1.5 million to investigate the potential application of fish in human healthcare. Tiersch's work involves freezing of sperm from zebrafish, swordtails and platyfish to look at preserving the genetic resources. Zebrafish are a useful biomedical model because they have the same basic genetics as humans, but are cheaper and easier to work with than mice or monkeys. Read more...
- Scotland’s aquaculture industry is set to benefit from the new European Maritime Fisheries Fund. The fund will help the sector adapt to new
circumstances, expand and create new jobs and promote fisheries
conservation. Read more...
