Example Embodiment
[0027] The present invention will be further described below in conjunction with embodiments.
[0028] 1. Cultivation and collection of food organisms
[0029] 1.1 Cultivation and collection of rotifers
[0030] Rotifers are generally cultured in a glass fiber reinforced plastic barrel with a conical bottom. There is a drainage control valve at the bottom of the glass fiber reinforced plastic to facilitate the timely drainage of dirty water rich in sediment. The culture water temperature is 26.5℃±2℃, the salinity is 34‰, and the dissolved oxygen is greater than 6mg / L. The rotifer culture density is controlled at 300-600 / ml. Before collecting the rotifers every morning, add the highly concentrated monocellular algae solution (rich in EPA / DHA) at a ratio of about 1.25ml:1L of the algae fluid: culture rotifer water. The density of chlorella and microchlorococcus is about 7 million / ml). After 1 hour, take the upper layer of water rich in rotifers and filter them with a 100-mesh sieve f...
