  • 한국산 홍어과(科) 어류(魚類)에 대한 분류학적(分類學的) 고찰(考察)과 국명(國名) 및 분포(分布) 범위(範圍)를 정리(整理)하기 위해 국내외의 표본(標本)과 문헌(文獻)을 통하여 재검토(再檢討)하였다. 그 결과 홍어과 어류는 4속(屬) 11종(種), 즉 Bathyraja bergi 바닥가오리, B. isotrachys 저자가오리, Dipturus kwangtungensis 광동홍어, D. macrocauda 도랑가오리, D. tengu 살홍어, Okamejei acutispina 무늬홍어, O. boesemani 깨알홍어, O. kenojei 홍어, O. meerdervoortii 오동가오리, Raja koreana 고려홍어 및 R. pulchra "참홍어" (국명개정(國名改稱)) 등으로 확인되었다. Dipturus속(屬)과 Okamejei속(屬)은 아속(亞屬)에서 속(屬)으로 승격되었기 때문에 각각 "살홍어속(屬)"과 "홍어속(屬)"으로 국명개정(國名新稱)하였고, Raja속(屬)은 "참홍어속(屬)"으로 국명개정(國名新稱)하였다. 분류학적 재검토의 결과 Bathyraja bergi 바닥가오리도 분포함을 알 수 있었다. 한국산 홍어과 어류의 종(種) 목록(目錄)과 분포도(分布圖)를 제시하였다.

  • Background: The biological information of fish, which include reproduction, is the prerequisite and the basis for the assessment of fisheries. Methods: The aim of this work was to know the reproductive biology with the first sexual maturity (TL50) and the spawning period for 58 mainly fish species in the waters around La Réunion Island (Western Indian Ocean). Twenty families belonging to the Actinopterygii were represented (acanthuridae, berycidae, bramidae, carangidae, cirrhitidae, gempylidae, holocentridae, kyphosidae, labridae, lethrinidae, lutjanidae, malacanthidae, monacanthidae, mullidae, polymixiidae, pomacentridae, scaridae, scorpaenidae, serranidae, sparidae; 56 species; n = 9,751) and two families belonging to the Elasmobranchii (squalidae, centrophoridae; 2 species; n = 781) were sampled. Between 2014 and 2022, 10,532 individuals were sampled covering the maximum months number to follow the reproduction periods of these species. Results: TL50 for the males and the females, respectively, ranged from 103.9 cm (Acanthurus triostegus) to 1,119.3 cm (Thyrsitoides marleyi) and from 111.7 cm (A. triostegus) to 613.1 cm (Centrophorus moluccensis). The reproduction period could be very different between the species from the very tight peak to a large peak covered all months. Conclusions: Most species breed between October and March but it was not the trend for all species around La Réunion Island.
