All about Fish Vetting – Dr Richmond Loh
Its flavour and texture definitely does not match the look of the fish… unless you like eating monster.
I’m so glad it’s reporting that they’ve gained the Marine Stewardship Council certification for sustainability because the Patagonian toothed fish is my favourite fish to eat.
Ever landed a fish and found this critter attached to the tongue of your fish? It’s common name is ‘tongue biter’!
Tongue biters are isopods (a type of crustacean) belonging to the family Cymothoidae.

Subject: new video: fishing with dynamite
Although dynamite fishing is no applied method in aquarium fisheries in the Philippines, nor elsewhere, we have chosen to include this documentary in our exhibition on Marine Aquarium Fishery and Trade in South East Asia.
Why?
This video unveils the reasoning of poor fishermen in Asia to use destructive fishing methods: They are cheap, they are effective and they provide a relatively high yield at low effort. Forced by the low prices paid for their product and lack of negotiating power, these fishermen will just try to make the most out of nothing.
This is not only true for dynamite fishing, but for cyanide use as well. It confirms the conclusion that any change in respect to environmental awareness and an attitude towards conservation will only develop when fishermen benefit from social justice and development in the same time.
Therefore we invite you to watch this video and apply what you take from it to the aquarium fishery in South East Asia too.

This was brought to my attention by Miriam – Thank you!
I hope that this technology could trickle down to be used in the ornamental fish industry…
ABSTRACT: Ornamental goldfish Carassius auratus were treated with whole cell (WC), extracellular product (ECP), outer membrane protein (OMP) and biofilm (BF) vaccines developed from the virulent Aeromonas hydrophila (AHV1; GenBank HQ331525.1) with and without the immunoadjuvant Asparagus racemosus. On various days post-vaccination (dpv), the treated fish were challenged with virulent A. hydrophila. These fish were monitored for survival, growth, specific bacterial reduction, and biochemical, haematological and immunological parameters. C. auratus attained 100% mortality within 7 d in non-vaccinated groups, whereas the vaccines helped to significantly (p ≤ 0.001) increase survival after 25 and 50 dpv. The vaccines with immunoadjuvant (ECP2, OMP2 and BF2 treatments) helped to reduce the Aeromonas load after the challenge, and serum albumin, globulin and protein levels were significantly (p < 0.01) improved in the OMP2– and BF2-treated groups. Haemoglobin and red blood cell counts were also significantly improved (p < 0.05) in the vaccinated groups compared to the control group. Additionally, haemagglutination occurred at the 1:12 dilution level in the vaccine plus immunoadjuvant-treated groups. Supplementing the vaccines with immunoadjuvant helped to improve phagocytosis to 54.07%, serum bactericidal activity to 14.6% and the albumin:globulin ratio to 7.6% in BF2 after 50 dpv. Its positive effect significantly (p < 0.05) increased in vaccinated groups compared to controls. Based on the results, especially with the OMP and BF vaccines, the immunoadjuvant A. racemosus helped to improve the efficiency of the vaccines. This approach will aid in the development of more efficient vaccines against bacterial infections affecting the aquaculture industry.

The Importance of Fish for Feeding Nine Billion
Fish has become a regular part of people’s diets across the world with both developed and less developed countries eating fish for a source of protein. As the world’s population becomes more affluent there will also be an increase in per capita protein needs. In meeting this, fish stands out as a protein source which has the ability to manage the resources and environmental issues well, said Dr Sibbel.
The importance of fish for food in the future also circles around its conversion capacity. Fish has one of the best conversion capacities meaning it can convert nutrients to protein much better than other animals. With the prospect that by 2050 the world will have nine billion mouths to feed, the aquaculture industry is expected to play a big role.
In line with this, Rick Sibbel DVM, Director, Merck Animal Health, discusses the utilization of protein sources to feed the world – http://www.youtube.com/watch?feature=player_embedded&v=BLjzXIAkZ3s#!.

The ‘immuno-booster ‘benefits of green tea in fish have been demonstrated in this article. Looks like we’d better get green tea into our diets too.

| Abstract: | In this study, we evaluated the effects of dietary green tea ethanol extract (GTE) supplementation on growth performance, body composition, and stress recovery of the juvenile black rockfish, Sebastes schlegeli. The fish (mean body weight, 8.1 ± 2.0 g) were fed fish meal diets that included 0 % (control), 1, 3, and 5 % GTE for 8 weeks. Weight gain, specific growth rate, feed efficiency, and protein efficiency rate were measured and compared among the fish in the different groups. The whole body and liver lipid compositions of fish fed the control diet were higher than those of the fish fed the GTE diets. Lysozyme activity in the plasma samples of fish fed the GTE diet showed an increasing trend in a dose-dependent manner. After administrating anesthesia (2-phenoxyethanol), the stress recovery time differed significantly between the control and the 3 and 5 % GTE diet groups and the mortality of fish fed on the GTE diet was significantly lower than that of the control group. In addition, plasma glucose levels in the fish fed the 3 % GTE diet showed a rapid recovery. Our results showed that the addition of GTE to the fish diet improved lipid utilization, lysozyme activity and stress recovery, and reduced total cholesterol levels in a dose-dependent manner.In this study, we evaluated the effects of dietary green tea ethanol extract (GTE) supplementation on growth performance, body composition, and stress recovery of the juvenile black rockfish, Sebastes schlegeli.
