Re there any wild bnative species left? Probably the primary freshwater game fish there is the LM bass, but there are native trout as well - and of course stockers. A method of fishing similar to high stick nymphing evolved there when the country was still closed to the west, but western style fly fishing is more common there days. A lot of Japan is mountainous and sparsely settled, the population is concentrated in the big cities. I have fished for trout there, but the regulations and methods of gaining access can be a bit confusing. The streams are lovely, though, and worth the effort. I've also fished for bass in the Imperial moat in Tokyo, which isn't quite as lovely in some places. -- Charlie... http://www.chocphoto.com Thanks |

Considerations on angling for stock fish. I have a numbre of objections to angling for stocked rainbow trout. These are based entirely on the facts known to me, and are not a result of "snobbery" or any other such silly considerations, as some people seem to assume. This is considerably more temperate and reasonable than what you posted on fishing for stocked fish just three days ago: "No responsible and conservation minded angler in full possession of his senses, and the knowledge of what he is fishing for, how it was obtained and treated, quite apart form the side-effects of eating such heavily chemically treated filth, would even contemplate "angling" for such." 1. The use of such fish is a massive drain on the environment. ... And this is quite different than this from three days ago: "Doubtless, but fishing for stocked rainbows causes heavy environmental damage." Most of your arguments against fish stocking are informed by an unreasonable conflation of aquaculture and fisheries management but at least you've learned to state them in a civil fashion without calling those who fish for stocked fish, (which includes the vast majority of roff btw), "criminally ignorant". -- Ken Fortenberry |

This is also a result of being fed on processed fishmeal, which concentrates various toxins, mainly in the fatty cells of such fish, and also the chenical and other complex drug residues used in their production. 5. I find the production of such animals purely for the purpose of playing with them distasteful. They are produced at great cost, damage, and danger to the environment, purely for the personal gratification of anglers who wish to fish for them. This is not at all the same thing as directly farming a food source. But the fish are materially the same, viz. farmed fish are fed artificially thus (if MC is right about the feed) have "accumulated poisons and toxins." We can calculate the environmental loads of creating a 3 lb. angling rainbow and a 3 lb. table rainbow, and perhaps these are different, but if they eat the same food are both not equally poisoned and poisonous? -- Don Phillipson Carlsbad Springs (Ottawa, Canada) |

Despite ongoing research, there is no substitute for fishmeal in the production of salmonid fish ( and quite a few others also). The same feed which produces contaminated farmed salmon also produces contaminated rainbows, and if brown trout are reared and stocked, the problems are the same, but somewhat worse, as it takes longer to feed browns on, as they have much slower growth rates. There are plenty of informational sites about the problems of rearing fish on fishmeal. The conversion ratios of willd fish protein to fishmeal, and the problems with the concentration of contaminants. This is independent of the drugs and chemicals being used at intensive rearing stations, which cause a whole other range of problems. The ONLY reared salmonid fish which are not dependent on fishmeal are those which are bred, and then released at the fry stage. Up till that point, they subsist on their egg-sacs. After that they must be fed, or they simply die. Despite intensive campaigns by various people and groups fish farming both in marine and freshwater environments continues to devastate the environment. The effluent form a trout farm will kill everything in a river if allowed to escape untreated. The problems with marine salmon farms are very considerably greater, as they also result in the complete destruction of anadrompus fish runs in the catchments where they are located. Despite this being known and well documented, permissions are still being granted for new farms in the UK.

By the way, you might also like to look at some of these sites. I have
purposely avoided citing or posting any particular one, pick whichever you like; http://www.google.co.uk/search?q=mal...GGL_en___DE230 This is only ONE of the substances in common use, there are dozens of them, not including carcinogenic colouring matter, other chemicals used for parasite control, etc and some complex antibiotics and other drugs.
