| pubmed-article:15225563 | pubmed:abstractText | Since oviparous fishes mobilize fat stores to produce eggs, we investigated the potential for deposition of gonadal ciguatoxins to the oil laden yolk sacs which nourish developing embryos, and characterized the effects of these toxins on finfish development. Results showed that ciguatoxins are more concentrated in the egg mass (0.18 ng/g) of a toxic fish than in the muscle (<0.04 ng/g). We used a microinjection technique in a Japanese medaka (Oryzias latipes) developmental fish model to mimic the maternal route of toxin exposure to finfish embryos. We describe the developmental effects of two preparations isolated from Caribbean great barracuda (Sphyraena barracuda): a highly purified toxin (C-CTX-1), and ciguatoxins extracted from the flesh of a toxic fish. C-CTX-1 induced a significant decrease in heart rate after four days, which did not persist with further development. Crude extracts from ciguatoxic fish flesh induced hyperkinetic twitching and severe spinal deformities. These effects were observed in embryos receiving as little as 5 pg/egg, and were consistently found in embryos receiving doses exceeding 10 pg/egg. The occurrence of twitching and spinal deformities increased in both frequency and severity with dose. Larvae suffering from spinal abnormalities were unable to orient themselves, and could not feed, resulting in mortality. The greater distribution of toxin to eggs as compared to flesh suggests that fish with low to moderate (0.5 ppb) flesh toxin levels would maternally transfer detrimental amounts of ciguatoxins to their offspring. | lld:pubmed |
