Embodiment Construction

[0016] The present invention comprises the following steps:

[0017] 1) Collect copepods, observe the copepods with oocysts, measure their body length, and conduct species identification to obtain a new Acartia sinjiensis. The mature individual body length is 680-740 μm, which belongs to Acartia sinjiensis order (Calanoida), spindle water flea family (Acartiidae), spindle water flea (Acartia); the collection of copepods can adopt plankton nets with a mesh size of 250 μm, and collect copepods in subtropical and tropical coastal waters.

[0018] 2) Inoculate and culture the new Daphnia spinosa in a glass container of 1-5 L, the body length distribution is: 60-230 μm for nauplii and 310-640 μm for copepod larvae, as the open biological bait of marine fish.

[0019] 3) Put the new daphnia spindle obtained in step 2) into the water tank to continue the cultivation, feed the bait during the cultivation process, siphon out the residual bait feces every day, and collect a part of naup...

Abstract

The invention relates to a method for cultivating larval stage feed copepods for ocean fancy fishes and relates to biological bait cultivation. The method comprises the first step of collecting the copepods, observing the copepods with oocysts, measuring the body lengths of the copepods, performing identification of species, and obtaining new acartia, wherein the mature individuals are 680-740 microns long and belong to calanoida, acartiidae and acartia; the second step of performing inoculated culture of the new acartia in a container, wherein the body-length distribution is that the nauplii are 60-230 microns and copepodite are 310-640 microns, and the nauplii and the copepodite serve as larval stage biological baits of marine fishes; the third step of placing the new acartia obtained through the second step in a water tank to go on being cultivated, feeding baits in the cultivation process, siphoning residual feed excrement each day, collecting part of the nauplii and copepodite to serve as larval stage feed for the ocean fancy fishes, adding the baits, and performing continuous cultivation for 1 month and then changing the water. The cultivation density of the new acartia can reach 2000/L.

Description

technical field [0001] The invention relates to a kind of biological bait cultivation, in particular to a method for cultivating copepods which are open baits of marine ornamental fish. Background technique [0002] There are many kinds of ornamental fish, different shapes, colorful, very beautiful, deeply loved by people. With the growth of economy, the development of production and the improvement of living standards, people's demand for leisure and enjoyable activities is also increasing day by day. Ornamental fish breeding and ornamental fish culture have become a symbol of healthy and elegant life. The ornamental fish leisure industry integrates breeding, exhibition, and competition, and integrates ecology, culture, and economy. It has become a happiness-oriented industry that meets people's pursuit of health, fashion, and leisure. [0003] At present, ornamental fish are mainly freshwater species, and there are still few artificially cultured marine ornamental fish. ...
