Abstract

The invention discloses a method for storing live trichodina. The trichodina and hydra are co-cultured according to an amount ratio of (5 to 20):1. The co-culture method specifically comprises the following steps of S1, feeding the trichodina and the hydra into a transparent storage container with water according to an amount ratio of (5 to 20):1, sealing an opening of the storage container by an air-permeable material, and ensuring that each hydra corresponds to the 3-5cm<2> water surface; S2, feeding daphnia into the storage container at the interval of two days, wherein each hydra corresponds to four daphnia; S3, counting the trichodina and the hydra at the interval of 24h, and maintaining the amount ratio to be (5 to 20):1. The method has the advantages that the operation is simple, the repeatability is strong, the storage time of trichodina is long, the storage amount of trichodina is large, and the storage method can be widely applied to the testing and research of the trichodina.

Description

technical field [0001] The invention relates to the research field of microbial living preservation, more specifically, the invention relates to a method for preserving living organisms of trichomonas. Background technique [0002] Trichomonas can parasitize various freshwater fish and cause various trichotillomaniasis. Trichotiliasis occurs in all regions of the country and throughout the year. The harm caused by trichomonas occurs frequently from April to July, during which the water temperature is maintained at around 20 to 28°C. The large number of trichomonas breeds and causes the fry and fingerlings of various freshwater fish to be infected. In severe cases, it can cause a large number of fry and fingerlings die. Trichomonas are transmitted by contact, and Trichomonas that leave fish can transfer hosts through various media such as water and aquatic organisms. The main factors causing the outbreak of trichotillomaniasis are poor water quality, insufficient food, ove...
