Embodiment 1

[0022] From 2007 to 2010, the three-dimensional culture experiment of rock worm-sea cucumber-gracilaria was carried out in the 2# pond of Dalian Neptune Longbin Haizhenpin Breeding Co., Ltd. The area of ​​the test pond is 50 mu, the sea cucumber reef is selected from the stone reef, and the sea cucumber seedlings are put into 100 / kg sea cucumber seedlings. In May, 2007, the sea cucumber seedlings were released. Pond culture management is a traditional sea cucumber pond culture management method. At the beginning of June 2007, using the method of paddling with small boats and splashing seedlings with water, the whole pool was sprinkled with large-scale rock worm seedlings (seed size: 1-1.5cm / tail) that had been artificially raised and bred in the middle, and the seedling density was 10,000 tails / mu. After the seedlings are cast, rock worm seedlings dive into the bottom of the pond, dig holes and live in the bottom of the pond, and feed on organic debris such as sea cucumber f...

Embodiment 2

[0024] From 2009 to 2012, a rockworm-sea cucumber mixed culture experiment was carried out in Nantangjia 2# pond, Rushan City, Shandong Province. The area of ​​the test pond is 100 mu, the sea cucumber reef is selected from the stone reef, and the sea cucumber seedlings are put into 200 / kg sea cucumber seedlings. In May, 2007, the sea cucumber seedlings were released. Pond culture management is a traditional sea cucumber pond culture management method. From May to June 2007, the method of paddling with small boats and splashing seedlings with water was used to sprinkle large-scale rock worm seedlings (seed size: 1cm / tail) that had been artificially raised and grown in the middle of the pond, and the seedling density was 1.5 . After the seedlings are cast, rock worm seedlings dive into the bottom of the pond, dig holes and live in the bottom of the pond, and feed on organic debris such as sea cucumber feces and benthic seaweed at the bottom of the pond. After one year of grow...

Abstract

The invention discloses a rock worm-gracilaria-sea cucumber pond mixing breeding method. A stereoscopic mixing breeding can be implemented in the inshore breeding ponds by manually putting in sea cucumbers, rock worms and gracilaria seedlings. Breeding space and nutrient substance of the sea cucumber pond can be effectively utilized to be converted into gracilaria plant productivity, wherein the gracilaria plant productivity is provided with economic value. Pond eutrophication can be prevented from happening. Pond sedimentary organic particulate matters of sea cucumber excrements and the like can be effectively utilized as baits for rock worms. Polluting rate of pond bottom which is caused by excessive accumulation of sea cucumber excrements can be reduced. Then, breeding benefits of a pond unit can be improved. Because the rock worms are high in economic value, benefit rate of a yield per unit area of the mixing breeding can be enhanced for 1-2 times. The rock worms can be caught in one time through a labor excavating method every three years. Pond bottom dredging and substrate renovation can be implemented at the same time in the catching process. The difficulty that substrate sludge of common aquaculture ponds of a common pond can not be cleared for a long time can be overcome.

Description

technical field [0001] The invention relates to a cultivation method, in particular to a rock worm-gracilaria-sea cucumber mixed cultivation method in a pond. Background technique [0002] Sea cucumber aquaculture is an important industry in aquaculture in northern my country. In 2011, the sea cucumber aquaculture area in my country's coastal areas reached 1 million mu, with an output value of nearly 20 billion yuan, accounting for nearly 1 / 3 of the regional mariculture industry output value, and has become a regional pillar. industry. However, with the rapid development of pond culture, the single pond culture mode has caused the occurrence of culture diseases and restricted the benefits of pond culture. [0003] The living characteristics of A. japonicus and the monoculture mode in ponds have caused the decline in the quality of its living environment and restricted the breeding benefits of ponds. According to the ecological theory and the actual situation of sea cucumber...
