controlling method of the time of sea cucumber artificial seed production through management of parents sea cucumbers in land farm

摘要

The present invention lowers the breeding water temperature of ginseng to 8 ℃ for 12 weeks and then raises it to 18 ℃ for 14 weeks. Steps (B) of spawning and releasing with spawning stimulation Steps (B), Generation of the fertilized eggs obtained in Steps (B) in a water tank (C), (C) Breeding in a wave plate until the ginseng generated in steps (C) grows to 0.5 g ( When ginseng grows to 0.5 g in steps d) and (d), excellent sea cucumber seedlings are provided by providing a method for early production and production time control through terrestrial management of mother sea cucumber, which consists of the step (E) of rearing ginseng in a special manger. It can contribute to increasing the income of sea cucumber farmers by stably securing the sea cucumber and extending the period during which sea cucumber seedling production is possible, as well as shortening the cultivation period of sea cucumbers.
