Lin-Xing Zhou, a technician at the recovery park, stated that in the past when the artificial breeding techniques for abalone were not mature, former breeders had to create the best timing for abalone to breed all night and carry out complicated breeding tasks for abalone. They often mocked themselves that they could still admire the beauty of sunrise at The Northeast Coast after they completed the task. Later, breeding techniques for abalone have become more mature and stable. Parent abalone would release sperm and eggs when their sexual glands mature and the change of water temperature reaches 3 to 5 degrees Celsius. Therefore, breeding tasks for abalone can be carried out in the daytime, and breeders no longer have to stay up, greatly enhancing the efficiency of abalone breeding.
Sperm and eggs released by parent abalone are collected by breeders who inseminate them in accordance with fixed proportions. When embryos in fertilized eggs begin to develop, breeders would carefully remove them to a cultivation pool. Newly-hatched abalone larvae are shell-less, and they float in the water for 2 to 5 days. When they grow transparent shells, these abalone larvae would attach to plastic corrugated boards hanging high in the pool and feed on microalgae on the corrugated boards. Abalone larvae are very tiny at this stage, and a breeder has to carefully search for the traces of these transparent babies to find them. Abalone larvae reproduced at the recovery park would gradually grow up after being carefully taken care of by breeders, and they would be released to Gongliao Maoao Bay Aquatic Life Reproduction and Conservation Area to extend the population of abalone, supplementing marine resources.
New Taipei City Agriculture Department Commissioner Wen Lee indicated that to enrich marine resources in New Taipei City, Gongliao Marine Resources Recovery Park cultivates abalone larvae between October and November each year and releases them to New Taipei City Maoao Bay Aquatic Life Reproduction and Conservation Area when their shells grow to 2 to 3 centimeters long. Additionally, the park invites students of neighboring elementary schools to release them to the waters in the hope that the breeding, cultivation, and release of abalone will increase marine resources and root the concept of conservation as well.
