Embodiment Construction

[0026] The following examples will further illustrate the present invention.

[0027] A prawn nursery farm in Dongshan, Fujian was selected as the experimental base, and the experimental material used was juvenile shrimp (Marsupenaeus japonicas, bate 1888) (weight 1.0±0.2g, body length 4±0.5cm). The Bacillus, lactic acid bacteria and photosynthetic bacteria used in the experiment are all single-bacteria preparations, which are the "Lisheng Bacteria King", "Lisheng Yogurt" and "Feng Shrimp Bao" products produced by the South China Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences. The water color nutrient used is the "Price" product produced by Zifeng Aquatic Materials Co., Ltd. The feed used was "Fuxing" prawn compound feed produced by Taiwan Hongguo Industrial Co., Ltd., with a crude protein content of 43% to 45%. The seawater used is filtered by sand filter, salinity: 28‰~32‰, pH 8.3~8.6, water temperature 25~29℃.

Abstract

A water quality control method for indoor cultivation of Penacus orientalis relates to a cultivation method of Penacus orientalis, and solves the problems that efficacy of probiotics used in the existing culture process cannot be given to full play and the like. Preparation before entry into a pond includes preparation of a culture pond, sterilization of culture water, adhesion of probiotics, inoculation of the probiotics and water environmental conditioning. Water quality regulation in the early stage of cultivation includes: continuously splashing mixed liquor 0.5L/m3 of the probiotics and rice hulls in water for 5-7 days after entry of Penacus orientalis into the pond until a great quantity of suspended fluctuant particles occur in the water and the transparency is 40-50cm, increasing aeration rate to fully aerate the fluctuant particles and part of the rick hulls, and increasing the water level by 5cm each day; and adjusting water quality in the mid-late stage of cultivation, namely mixing live bacteria into daily fodder, changing 15%-30% of water once every 7-15 days, and splashing quick lime once every 10-15 days.

Description

technical field [0001] The invention relates to a method for cultivating prawns, in particular to a method for controlling the water quality of indoor aquaculture of prawns using a biofilm and biofloc system. Background technique [0002] The quality of water quality management is the key to the success of shrimp farming. In the indoor shrimp culture system, due to the high breeding density, single artificial feed feeding, relatively simple ecosystem and low environmental carrying capacity can easily lead to the rapid accumulation of toxic pollutants in the water body, resulting in deterioration of water quality. Frequent water changes, water purification drugs (adsorbents, oxidants, etc.), use of recirculating aquaculture systems, and probiotics are often used to maintain a suitable breeding environment. The discharge of a large amount of aquaculture wastewater not only wastes manpower and material resources, increases the cost of aquaculture, but also pollutes the environ...
