Seawater-sprinkling keep-alive transporting method for abalones

Abstract

The invention relates to keep-alive transporting methods, belongs to the field of keep-alive transporting of live / fresh foods and provides a seawater-sprinkling keep-alive transporting method for abalones. The method comprises the following steps: carrying out keep-alive pretreatment: putting fished disease-free live abalones into a temporary-culture water tank for feeding-stopped temporary culture, wherein the time for temporary culture is 24-36 hours; transferring the abalones, subjected to temporary culture treatment, onto a keep-alive transporting vehicle, and sprinkling cold seawater to cool to the temperature of 6-12 DEG C, wherein the cooling manner is uniform-speed cooling; adopting cold seawater combined sprinkling during keep-alive transporting, wherein raining type sprinkling and atomizing type sprinkling are combined; when the vehicle is close to a transportation destination, carrying out gradual sprinkled heating-up by using seawater, so as to adaptively wake up the abalones, and enabling the temperature of the abalones to rise to the mean daily temperature of seawater which is located at the destination; after the vehicle reaches the destination, putting the live abalones, which undergo the ending of live keeping, into the seawater of the destination for culture, and gradually recovering the normal feeding amount. The method provided by the invention has the advantages that the keep-alive transporting survival rate of the abalones is increased, the transportation cost is reduced, and the economic benefit is increased.

Description

technical field [0001] The invention relates to a transportation method for keeping alive, in particular to a transportation method for keeping abalone alive by spraying sea water. Background technique [0002] Abalone is a primitive marine shellfish, a single-shell mollusk with only half of a thick, flat and wide shell. Abalone can live in waters with a salinity of 28-35g / L. When the salinity is lower than 25g / L, the growth starts to be abnormal, and when the salinity is lower than 20g / L, it cannot grow. Abalone is cold-resistant but not high-temperature resistant. Life is abnormal when the water temperature is 28°C, death occurs when the water temperature is above 30°C, appetite is strong at 15-20°C, food intake gradually decreases when the water temperature is below 7°C, and basically stops eating at 0°C. During the whole storage, transportation and sales process of abalone after harvesting and being put on the market, due to the change of living conditions, if the neces...
