Problems solved by technology

However, in the clownfish population, there can only be one pair of broodstock with mature gonads, that is, one female and one male, and the rest are juveniles whose gonads are waiting to develop. This feature has become a bottleneck restricting the mass cultivation of clownfish.

Embodiment Construction

[0046] In August 2008, when the artificially propagated A. clarkii juveniles grew to 2 cm, 30 larger individuals (120 in total) were selected from 4 pairs of wild broodstock offspring as backup broodstock for cultivation. Breeding in 4 0.5m 3 Carry out in fiberglass barrels, 30 tails per barrel. Cultivated in running water, feed self-made compound feed before body length 5cm, 4 times a day (8:00 / 11:00 / 15:00 / 18:00), after body length 5cm, feed fresh squid, shrimp meat and algae powder soft feed. The artificial compound feed is made by draining fresh shrimp meat and then homogenizing it, then adding 1% spirulina powder, 2% vitamin C and 10% flour, stirring evenly, pressing into thin slices, air-drying, sealing and storing in a refrigerator at 4°C for later use , The artificial compound feed is made once every 3 months. The production method of the soft pellet feed is to homogenize the fresh shrimp meat after draining the water, then add 1% spirulina powder and 2% vitamin C, s...

Abstract

The invention relates to a method for the totally-artificial batch culture of parent fish of clown fish, which comprises the following steps of: when juvenile fish of the clown fish propagated artificially grows to 2 centimeters in average body length, selecting a certain quantity of high-quality individuals as reserve parent fish; culturing the selected reserve parent fish in a cultivation pond by adopting a mode of group culture; when the reserve parent fish is cultured for 180 days, starting to perform pairing operation, and obtaining artificially-paired parent fish to be cultured in batches by adopting a safe and efficient pairing mode of combining batch pairing with cross pairing; and performing enhanced culture on the paired parent fish in a parent fish pond, and ensuring the high quality of the artificial parent fish through the ripening-induced technology for the parent fish of combining the environmental ripening-forced regulating and control measure with the nutrition ripening-forced regulating and control measure. The method improves the totally-artificial culture speed and pairing success rate of the parent fish of the clown fish, ensures that the spawning effect of the parent fish is the same or close to that of wild parent fish, solves the problem of deficient parents in the culture of the clown fish, and has a significance for the development of marine ornamental fish aquaculture.

Description

technical field [0001] The invention relates to a method for fully artificially cultivating broodstock of clownfish in batches, which is suitable for selecting seedlings from juvenile clownfish artificially propagated and cultivating broodstock in batches under controllable conditions. Background technique [0002] The clownfish belongs to the damselfish family (Pomacentridae), the sea anemone fish subfamily (Amphiprioninae), and the traditional taxonomy divides this subfamily into the genus Amphiprion (also known as the genus Anemone) (Amphiprion) and the Echinococcal sea from the perspective of morphology. There are 28 species in the genus Premna, and only 1 species in the genus Premna in the world. Therefore, there are 2 genera and 29 species in the subfamily Anemone. They are cute elves in coral reefs and important tropical seawater ornamental fish. Due to their unique and interesting symbiosis with sea anemones, they have become the most popular species in seawater aqua...
