Summary:The present invention provides a method for controlling early production and production timing through land management of a mother sea cucumber comprising: (A) a step of decreasing breeding water temperature of wild ginseng to 8℃ for 12 weeks and increasing the same to 18℃ for 14 weeks; (B) a step of scattering and equating the wild ginseng of the (A) step with a scattering stimulus through a water temperature stimulus, a surface stimulus, and a drying stimulus; (C) a step of generating a fertilized egg obtained in the (B) step in a water tank; (D) a step of raising tooth ginseng generated in the (C) step in a raising plate to grown to 0.5 g; and (E) a step of raising the tooth ginseng in a special net when the tooth ginseng grows to the 0.5 g in the (D) step. The present invention stably secures many sea cucumber seedlings; extends a period for sea cucumber seedling production; shortens a cultivating period of the sea cucumber; and increases an income of a sea cucumber cultivating fishery household. 본 발명은 모삼의 사육수온을 12주간 8℃ 까지 낮추었다가 14주간 18℃ 까지 올려 관리하는 단계(가), (가)단계의 모삼을 수온자극, 표면자극, 건조자극을 통해 산란자극으로 산란과 방정시키는 단계(나), (나)단계에서 얻은 수정란을 수조에서 발생시키는 단계(다), (다)단계에서 발생된 치삼이 0.5 g으로 성장할 때까지 파판에서 사육하는 단계(라), 및 (라)단계에서 치삼이 0.5 g으로 성장하면 치삼을 특수망지에서 사육하는 단계(마)로 이루어진 어미 해삼 육상관리를 통한 조기생산 및 생산시기 조절방법을 제공함으로써, 우량의 해삼종묘를 안정적으로 확보하고, 해삼 종묘생산이 가능한 기간을 확대할 뿐만 아니라, 해삼의 양식기간을 단축시킬 수 있어 해삼양식 어가의 소득증대에 기여할 수 있다.
