| Abstract: | (1) The basic food organisms in prawn culture pond are mainly composed of such species as Neomysis awatschemsis. Sinocalanus laevidactylas, Schmackeria dubia, Corophium spp.. They show effective results to culture plankton by artificial nourishment. (2) In the stage of prawn culture, twenty-three predator fishes were found. They are chiefly composed of such species as Portunus trituberculatus, Nibea albiflora, Eleutheronema tetradactylum, Lateolabrax japonicus, Triclentiger trigonocephalus. Eggs and larvals always appear in May and June. Predator fishes raised and grow in July and August. After the middle of September predator fishes decrease obviously. (3) The experiment to treat predator fishes with 1 ppm in pond was carried out and has got a satisfactory result. All fishes had been killed, but no prawn loas killed under this treatment. |
