Eric Roderick, CEO Fishgen

Eric has over 30 years of research experience at the University of Wales, Swansea, and an Aquarist and Ornamental fish breeder for over 40 years.

Fishgen Limited, is a University of Wales, Swansea company established to commercialise and promote the technologies and products developed in research programmes in Aquaculture. Its main product the YY supermale technology is an environmentally friendly alternative to hormone treated sex reversed tilapia, with a worldwide customer base.

To complement the organic nature of its fish, the focus then shifted to nutrition, with the emphasis on a totally sustainable organic aquaculture feed. Small scale trials with Tilapia fingerlings using Dragon Feeds polychaete diets have produced excellent growth rates and a superb feeding response. When fed to tilapia brood stock, a marked increase in spawning was observed, and also higher fecundity.

Observational results from feeding the Polychaete diets to a range of Marine ornamentals (over 50 different species) both wild caught and captive bred, and freshwater ornamentals (well over 100 species) were outstanding, with 100% acceptance of the diet even among very finicky feeders and even included many fish that had only been fed on live or frozen natural diets. I have tried most new ornamental feed products produced over the last 10 years and have never seen such a feeding response.

With dwindling stocks of traditional wild caught "fishmeal species" from over fishing, cultured polychaetes replacing wild-caught, non-sustainable fishmeal is probably the most significant development in the fish feed industry globally. Fishgen is proud to be one of the first companies to benefit from this technology.
