Problems solved by technology

However, the requirements of Siamese crocodiles on water quality, water temperature, bait, breeding density, sex ratio and breeding environment conditions are very different from those of other freshwater crocodiles under captive breeding conditions, and it is difficult to control them. It is very difficult to successfully mate and reproduce, which seriously restricts the healthy development of the breeding industry of this species

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0033] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0034] A kind of artificial propagation method of crocodile, comprises the following steps:

[0035] Step 1. Provenance selection

[0036]In the wild, adopt the non-injury trapping method to catch young Siamese crocodiles, and select the young individuals that can reproduce. It is required that the body length of the female crocodile should be more than 100cm, and the body length of the male crocodile should be more than 130cm. Alligators with intact tails and limbs are regarded as breeding crocodiles;

[0037] Step 2. Domestication before pairing

[0038] Such as figure 1 As...

Abstract

The invention discloses an artificial breeding method for Crocodylus siamensis. The method includes the steps of provenance selection, domestication before pairing, breeding place setting, manual pairing and Crocodylus siamensis egg collection and hatching. The main problems, about provenance selection, pairing, pairing period selection, sex ratio setting, density setting, bait preparation and breeding and hatching environment setting, of a present artificial breeding method for the Crocodylus siamensis can be effectively solved, damage and death in the breeding mating process are remarkably reduced, the spawning rate of the female Crocodylus siamensis is remarkably increased, the hatching rate of Crocodylus siamensis eggs is remarkably increased, efficient artificial breeding of the Crocodylus siamensis is achieved, healthy Crocodylus siamensis larvae are acquired, and solid technical supports are provided for expanding the breeding population of the Crocodylus siamensis, promoting species protection and developing large-scale breeding.

Description

technical field [0001] The present invention relates to aquaculture technology, more specifically, relates to a kind of artificial reproduction method of Siamese crocodile. Background technique [0002] Siamese crocodile is also called Siamese freshwater crocodile and Singapore small crocodile. It is mainly distributed in Borneo, Indonesia, Malaysia, Thailand and Vietnam in Southeast Asia. It is a medium-sized crocodile, the longest adult crocodile can reach 4 meters, and the common one is 3 meters long. When the young crocodile hatches, it is about 25 cm long. The snout of the Siamese crocodile is medium in length, slightly concave, about 1.5 to 1.6 times the width of the base of the snout. There is a pair of short sharp ridges in front of the two eye sockets, and there is an obvious socket between the two eye sockets on the forehead, and the squamous bone protrudes into a high crest. [0003] Siamese crocodile is a world-class endangered species. As an excellent freshwat...
