本文研究了河豚毒素（TTX）对人工饲养的老虎河豚幼鱼放生到有捕食者的中生态环境后存活的影响，以阐明TTX的生态学意义。将含有三种不同浓度TTX的微丸[0为对照，7和14小鼠单位(MU)/g日粮]喂给无毒人工饲养的t。10天。除对照组外，TTX在鱼的各组织中均有积累。注射TTX对鱼的存活和生长没有影响。每组100尾鱼在TTX给药后一起放生到一个有捕食者（Lateolabraxsp.）的盐池中生态（2650 m2），放生5天。7 μ μ TTX/g饲料和14 μ μ TTX/g饲料的放生成活率（62%）显著高于对照鱼（32%）。
We examined the effects of tetrodotoxin (TTX) administration on artificially raised tiger pufferTakifugu rubripesjuvenile survival after release into a mesocosm with predators to clarify the ecological significance of TTX. Pellets containing three different concentrations of TTX [0 as the control, 7 and 14 mouse units (MU)/g diet] were fed to non-toxic artificially raisedT. rubripesjuveniles for 10 days. TTX accumulation in the various tissues of fish was detected except for in the control diet group. TTX administration did not affect survival or growth of the fish. One hundred fish from each diet group were released together after TTX administration into a salt pond mesocosm (2650 m2) with predators (Lateolabraxsp.) for 5 days. Survival after release was significantly higher in both the fish fed with the 7 MU TTX/g diet (62%) and the 14 MU TTX/g diet (74%) than in the control fish (32%).
