实验红鲫水族箱饲养技术

目的 为完善实验红鲫标准化内容建立水族箱饲养技术。方法 总结多年来的实践经验，并参考文献。结果 选择大小约为1 200 mm×480 mm×755 mm(长×宽×高)的长方形水族箱，设置增氧泵、过滤器、照明灯等配套设施，模拟池塘生境进行布景。注入曝除氯气3 d后的自来水，保持水温在18～24 ℃，溶氧量在≥6 mg/L，酸碱度在pH7.5～8.5、光照在100～200lx、硬度(CaCO3)在95～105 mg/L、氨(NH3)浓度在≤0.02 mg/L等。按100 mm体长的80尾/m3水体的饲养密度，投放质量合格的实验红鲫。每日投喂全价颗粒饲料1～2次，每3～7 d部分换水1次，14～21 d全部换水并清洗水族箱1次，坚持做好日常管理与清洗消毒工作。结论 本文描述的饲养技术适合于用水族箱饲养实验红鲫。

Husbandry of Laboratory Red Crucian in Aquarium

In order to improve the standardized content of laboratory red crucian carp,the aquarium suitable husbandry strategies for this kind of fish is proposed by summing up many years of practical experience and referring to the literature.Select the size of about 1200 mm × 480 mm × 755 mm (length × width × height) of the rectangular aquarium, set aeration pumps, filters, lighting and other kits, simulated pond habitat for scenery. After aeration 3 days long，the tap water is injected into the aquarium. The water quality and the environment of the aquarium were controlled goodly, maintaining the water temperature at 18-24 ℃, dissolved oxygen in ≥ 6 mg/L, pH value of pH7.5-8.5, light in the 100-200lx, hardness (CaCO3) in 95-105 mg/L, ammonia (NH3) concentration in less than 0.02 mg / L and so on. As an example of 100 mm length fish, according to the density of water per cubic meter with 80 tail fish, put the laboratory red crucian carp into the aquarium. Feeding the full-price pellets daily for 1 or 2 times, replacing part of the water every 3-7 days for 1 time, replacing all of the water for 14-21 d and cleaning the aquarium once, insisting on daily management and cleaning and disinfection. The technical method described in this article is a husbandry technical strategy suitable for laboratory red crucian carp in aquarium.
