中文摘要 | 海域箱網稚魚中間育成之成效,關係著海洋牧場稚魚放流。為瞭解海域箱網稚魚 中間育成之成效,故自1992年12月起至1996年11月止,在高雄縣永安鄉之海域箱網共放養 稚魚23梯次,並將放養之資料與現場海況資料詳細觀察比對,得知 (一)高雄縣永安海域箱網中間育成,在春秋兩季稚魚之成長率及存活率最好;故以經濟 的眼光來看,此兩季應密集且多梯次的飼養,而每梯次之馴養時間以一個月為佳。 (二)海域箱網養殖時,稚魚初放養之魚體長以10cm以上為佳。 (三)在高雄縣永安鄉從事海域箱網養殖之海域,其海流之平均流速在10cm/sec以內,而 箱網養殖之成長率及存活率與該海域海流流速無絕對相關性。 (四)高雄縣永安鄉海域箱網中間育成以冬夏二季風浪造成之稚魚死亡影響最大,風浪越 大,其死亡率越高。 由以上的結論指出,海域箱網中間育成之成效和波浪有關,而波浪的大小又和季風息 息相關,故海域箱網的中間育成過程應避開冬夏二季。 |
英文摘要 | A successful releasing fish into a marine fish farm concerns the intermediate fish breeding in the marine aquaculture cages. To realize the effectiveness of breeding fish in the cages, 23 classes of the breeding records, obtained in the cages arranged at the Kaohsiung-Jouan sea area from September 1992 to September 1996, were compared with the original fish data. There are four interesting results based on the investigation of the marine aquaculture cages as follows: (1)spring and autumn are the best two seasons for both the rates of growth and subsistence of fish intermediately bred in the marine aquaculture cages. (2)The body length of young fish imigrating into the marine aquaculture cages should not less than 10 cm. (3)Since the current speed during spring and autumn at Jouan sea area is always under 10 cm/sec, the two rates of growth and subsistence of fish seems to have no direct relation to the current speed. (4)the larger wind waves during summer and winter at Jouan sea area, the higher death rate of young fish in the marine aquaculture cages. The effectiveness of the intermediate breeding of fish in the marine aquaculture cages depends on the local waves that are more significant during summer and winter. |
