Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a method for artificially mass-breeding Basilisk fish, especially Basilisk macula and Brown Basilisk fish, so as to solve the difficulties in juvenile fish source and domestication in the process of artificial breeding of Basilisk macula and Basilisk basilisk , the newly hatched individuals are small in size, and the larvae are highly stressful, resulting in high mortality. Key technologies such as fish transportation

Embodiment 1

[0030] Implementation steps:

[0031] 1. Breeding of broodstock

[0032] In July 2006, the wild-caught brown basketfish (body length 5-10cm) was cultured in shallow sea cages in the southern coast of my country, and the grouper was mixed with an average breeding density of 5 fish / m 3 , Feed Penaeus monodon prawn feed, the daily feeding amount is 2% of the total weight of the basket fish, and assist in feeding 5-7kg of branched seaweed per month, while pecking at the algae attached to the cage, and the breeding time is 21 months.

[0033] 2. Breeding of broodstock

[0034] Select female fish weighing up to 450g / tail, male fish weighing up to 350g / tail, 56 brown basket fish and 33 females. Use the transport boat to inflate and transport for 2 hours, and then use the transport vehicle to inflate and transport for 3 hours to the nursery site. The catch time is 4:00, no feeding before transportation, and 0.8m is used for transportation. 3 The water tank is used for shipment, and t...

Embodiment 2

[0049] Implementation steps:

[0050] 1. Breeding of broodstock

[0051] In August 2007, wild-caught yellow-spotted basketfish (body length 5-10cm) were cultured in shallow sea cages in the southern coast of my country, with an average breeding density of 15 fish / m 3 , Feed Penaeus monodon prawn feed, the daily feeding amount is 2% of the total weight of the basket fish, supplementary feeding of branched seaweed, 5-7kg per month, and at the same time pecking at the algae attached to the cage, the breeding time is 3 years.

[0052] 2. Breeding of broodstock

[0053] Select female fish weighing more than 450g / tail and male fish weighing more than 350g / tail, including 51 macular basketfish and 22 females. Use a transport boat to inflate for 1 hour, and then use a transport vehicle to inflate for 2 hours to the nursery site. The start time is 6:00, no feeding before transportation, and two 0.5m 3 The water tank was shipped, and the water temperature was lowered to 16°C by addin...

Abstract

The invention discloses an artificial breeding method for siganus oramin. Siganus canaliculatus and Siganus fuscesens are common fish stocks of Siganus, the physiological characters, reproductive habits and the breeding methods of the Siganus canaliculatus and Sigauns fuscesens are more similar, the problems that the source and domestication are difficult, newly hatched individuals are small in body size, the death rate caused by strong irritability of larva is high, a systematic artificial breeding technique is in shortage, the breeding offspring seeds are mainly from natural seedlings captured from ocean, and the like exist in the artificial breeding process. The artificial breeding method adopts the technical measures of parent fish culturing, cultivation, artificial spawning and incubation, larva cultivation pool preparation, cultivation water quality conditioning, staged bait feeding and juvenile fish transportation, so that the industrialization production of parent fish supply and seedling culture is realized, and the technical problems of artificial spawning and incubation of parent fish, selection and enrichment of larvae bait, water quality regulation and control, larva transportation and the like in the artificial breeding process of Siganus canaliculatus and Siganus fuscesens are systemically solved. The spawning rate of the cultivated parent fish can reach more than 65 percent, the average spawning fertility rate can reach more than 85 percent, and the survival rate of artificial breeding is 10.7 percent-27 percent.

Description

technical field [0001] The invention relates to a method for artificial breeding of basket fish, in particular to a method for raising broodstock and seedlings of macular basket fish (Siganus canaliculatus) and brown basket fish (Siganus fuscescens), belonging to fish breeding and culture in aquaculture technology field. Background technique [0002] Siganidae (Siganidae) fish, referred to as basket fish, are widely distributed in the East my country Sea, South China Sea and Taiwan waters of China. Yellow-spotted basketfish (Siganus canaliculatus) and brown basketfish (Siganus fuscescens) are common fish species in the family. The physiological characteristics, breeding habits and breeding methods are relatively similar, and the meat is delicious. With the growth of population and the improvement of people's living standards, people's demand for basket fish continues to expand. Basket fish occupies a relatively important economic position in my country's marine fishery. Bask...
