preparation example Construction

[0047] The preparation method of the domesticated food comprises the following steps:

[0048] 1) fresh banana peels and fresh stems of Dendrobium candidum are beaten into paste;

[0049] 2) activating the yeast dry powder;

[0050] 3) According to the proportion, mix the activated yeast, the fresh banana peel made into paste, the fresh stem of Dendrobium officinale and other raw materials, and ferment under the conditions suitable for yeast fermentation to obtain domesticated food.

[0051] In step 2), the activation of the yeast dry powder is an existing technology, and conventional methods can be used for activation, such as activation with glucose water. As specifically listed in the examples of the present invention, every 450 g of dry yeast powder can be activated with 150 grams of glucose and 10 liters of pure water at 35°C.

[0052] Preferably, in step 3), the fermentation condition is: sealed fermentation at 35-38°C for 1-10 hours.

[0053] By adopting the domesticat...

Embodiment

[0061] (1) Preparatory work: Disinfection of breeding ponds and tools; preparation of breeding water in accordance with the conventional culture standards of Penaeus vannamei.

[0062] (2) Shrimp seedling selection: select the larvae of Penaeus vannamei with good quality about 0.8cm~1.2cm in body length as the shrimp seedlings, observe with the naked eye, the individual size of the shrimp seedlings is uniform, the body color is transparent, and the vitality is strong; The tentacles of the seedlings should be pointed forward together, the tail fan should be fully opened, and the abdominal segment should be longer; the body surface of the shrimp seedlings should be clean, free from parasites and damage; The ratio of the muscle width to the intestinal width should be greater than 4:1; most of the shrimp seedlings are lying on the bottom in the static state, and there is a top water phenomenon after being stimulated by the water flow. The shrimp seedlings used in this example were...

Abstract

The invention belongs to the technical field of aquaculture, and particularly relates to a penaeus vannamei feeding method. According to the method, in a penaeus vannamei culture process, cladocera isadopted as feed or one of feed. Penaeus vannamei cultured by adopting the special feeding method is larger than commonly-cultured penaeus vannamei in specification, and the body weight of each penaeus vannamei is three times or above that of each commonly-cultured penaeus vannamei. Moreover, by adopting the special feed and the feeding method, a yield of the penaeus vannamei is comprehensively raised, and the yield per mu is up to 1000 kg or above; and the quality of the penaeus vannamei is optimized, the penaeus vannamei bodies are smooth in surface, and the penaeus vannamei has good activity, does not have off-odour, pasts drug tests, are uniform in specification, and reach the specifications completely.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a feeding method for Penaeus vannamei. Background technique [0002] Vannamei white shrimp, scientific name Vannamei shrimp, Penaeus vannamei. It is a wide-temperature and wide-saline tropical shrimp, belonging to Arthropoda, Crustacea, Decapod, and Swimming suborder. It is native to the waters of the Pacific coast of South America and is one of the three world-recognized excellent shrimp species. It looks exactly like Chinese prawns and Moji prawns, and its average lifespan can be at least 32 months. Adults can be up to 24cm long, with a thin carapace. The normal body color is light blue-gray, and there are no markings on the whole body. The legs are often chalky, so they are called white-legged shrimps. Penaeus vannamei has thin shell and fat body, delicious meat, high meat content and rich nutrition. [0003] Since my country introduced it in the 1990s, the...
