| 内容記述 | Recently, skeletal abnormalities have been found in a majority of the artificially reared fish in Japan. These deformed fish are not suitable either as seedlings for commercial farming or release to the ocean for recapture purposes. In this study, detailed observations were made on the morphological deformation of vertebrae and colour pattern in developing juveniles of the parrot fish Oplegnathus fasciatus in order to obtain basic information necessary for prevention. Specimens used were reared during 1978 at the Ehime Prefectural Fisheries Experimental Station. Adults maintained in spawning tanks produced fertile eggs, which hatched into larvae. These were maintained on cultured rotifer, Artemia nauplii and minced meat of fish. Skeletal deformation was inspected through the use of soft X ray and a comparison of meristic characters was also conducted. The 1,716 specimens studied ranged between 10 to 55 mm in standard length. Results obtained may be summarized as follows : 1. Vertebral deformation was found in about 19% of observed specimens. The main symptoms were lordosis, shortening and curvature, which were concentrated characteristically in the marginal portion between the abdominal and caudal vertebrae and the caudal peduncle. 2. No clear differences between normal and deformed specimens in standard length-body height relation were found. However while the ratio of body height to standard length were mainly 45-50% those fish exhibiting a ratio of more than 50% also had a frequency of greater than 50% deformity. 3. Morphological irregularity of black stripe occurred in 37% of the observed specimens. Abnormalities were concentrated remarkably on the black stripe of the caudal portion. | |||||||||||||||||||||||

| 内容記述 | 海産魚における人工種苗の形態異常に関する基礎的知見を得るため1976~1978年の各生産時期に飼育したイシダイの幼稚魚のうち78年の標本を中心に骨格,斑紋の異常を観察しつぎの結果を得た。1)骨格の形態異常は約19%認められ,症状は脊柱前湾症が最も多く,ついで短軀,湾曲,後湾症などであった。2)椎体の異常部位は,斑紋異常個体と正常個体でやや異なるが,全体の傾向としては腹椎から尾椎への移行部と尾柄部に集中していた。3)骨格の正常魚と異常魚の間には体長体高の相関に有意差は認められず,外部形態から骨異常の有無を知ることは困難であるが体高比(体高/体長×100)が55%以上は骨格異常の個体だけで占められていた。4)斑紋の異常は37%認められ,尾部の横帯に特徴的に出現し,その主な症状は横帯の結合,未形成,分岐などであった。5)斑紋異常と骨格異常の関連は,斑紋は正常で骨格に異常のある個体が16.3%,斑紋も骨格も共に異常がある個体が23%であった。 | |||||||||||||||||||||||
