天然河鲀,通常具有河鲀毒素(TTX),并且对 TTX 具有很强的抗性。最近,日本各地兴起养殖河鲀热,据报道,养殖的河鲀几乎没有毒性。其理由是:①养殖河鲀没有机会摄食具有 TTX 的饵料;②养殖河鲀本身对 TTX 缺乏抵抗力。Matsui 氏等提出,当养殖河鲀摄食了有毒的河鲀卵巢时,能看到某种程度的中毒现象。本文就养殖河鲀的毒性进行了较详细的研究。材料与方法1.材料:供试验用的红鳍东方鲀(Fu-gurubripes rubripes)取自福井县敦贺湾26
Natural river grass, usually with tetrodotoxin (TTX), and is highly resistant to TTX. Recently, aquaculture heat has emerged in various parts of Japan, and it is reported that farmed river clogs are almost non-toxic. The reasons for this are: (1) There is no chance of feeding pigeons with TTX for breeding pigeons; (2) Breeding pigeons themselves are not resistant to TTX. Matsui et al. Suggested that some degree of poisoning can be seen when the breeding reeds consume the poisonous nocturnal ovaries. This paper conducted a more detailed study of the toxicity of breeding river gall. Materials and Methods 1. Materials: Fu-gurubripes rubripes were collected from Dunha Bay, Fukui 26
