Fishy failures
Re: "Time to solve fish invasion", (Editorial, July 19) and "Really fishy business", (Editorial, July 6). The BP editorial highlights the problem created by an invasive species of freshwater fish called blackchin tilapia. Tilapia are the third world's salmon, a valuable food fish rich in protein and easy to cultivate.
Unfortunately, the Thai Fisheries Department was unable to contain them, a universal problem that inevitably occurs when non-native species are imported, no matter the purpose, and are capable of finding a suitable habitat upon escape.
Apparently, the Fisheries Department suffers from a common problem plaguing the Thai bureaucracy: their staff have insufficient education commensurate with their responsibilities. Other possible reasons for their failure are not the subject of this letter.
In seeking a solution for invasive freshwater fish, one should look to the US $300 billion (10.9 trillion baht) aquaculture industry. Great sophistication now characterises the cultivation of freshwater fish, with genomics being an integral part of the industry's growth in recent years.
The solution is to employ a company specialising in fish genomics to create a genetic variant that is incapable of reproducing, produce large numbers of fingerlings in captivity, and release them to breed in the affected waterways. This is no longer a novel idea. Those responsible for the import of the offending species should foot the bill, which, compared to the financial burden of the invasive fish, would be modest.
