Description

A kind of hatching cage for being suitable for placing Odontobutis obscura tube for laying eggs
Technical field
Fish oviposition Cultivating techniques field is the utility model is related to, especially design is a kind of is suitable for placing Odontobutis obscura tube for laying eggs Hatching cage.
Background technology
Odontobutis obscura, Perciformes, happiness move in stream and the more water plants of lake offshore, rubble, stone gap, the bottom of silt.With shrimp, Small fish is Major Foods.It is distributed widely in east China each province waters.Though individual is small, its meat content is high, and fine and tender taste is tasty, Liked by lower Yangtze and all province masses in south, particularly cook after fire-cureing, do not have flavor, be classified as top grade.With people Differentiation of the Diet concept from mass type to auxotype, the Odontobutis obscura valued of not behaving in the past be increasingly subject to the green grass or young crops of consumer Look at.As the quickening of socio-economic development and the pollution of natural water area aggravate, the living environment of Odontobutis obscura is constantly on the hazard, and provides Source amount reduces sharply, this causes the market price of Odontobutis obscura to climb up and up, risen to 150 yuan/kilogram or so, and supply falls short of demand. According to the market demand, carry out the artificial breeding of Odontobutis obscura, its economic benefit will be very considerable.
Odontobutis obscura is how ripe in 1 rheological properties, and the minimum ripe individual body of female grows 5.7 centimetres, and 4.7 grams of weight, 4 ~ June is oviposition Mating period.Raun mature coefficient increased dramatically at the beginning of 4 months by the end of March, and early April reaches maximum 21.21%, drastically declines afterwards, By the end of July minimum 0.59%.Indivedual fishes have hermaphroditism, and left side is spermary, and right side is ovary.Spawning ground is more leeward In arm of lake.Odontobutis obscura artificial propagation establishes suitable laying nest and its hatching apparatus firstly the need of for Odontobutis obscura.
Nowadays there is the hatching apparatus of many kinds of Odontobutis obscuras on the market, the China such as Patent No. 201220362224.3 is real A kind of Odontobutis obscura hatching apparatus, including stent are disclosed with new, several hatcheries are installed on the stent, are each incubated The bottom for changing pond is equipped with draining seedlings picking mouth, and each hatchery is at least provided with a spilling water；It is provided with the top of stent and gas Connected tracheae is pumped, is placed with aeration head in each hatchery, the inlet end of aeration head is connected with tracheae；In the upper of stent Portion is provided with feed pipe, and lower water supply is placed with hatchery, and the water inlet end of lower feed pipe is connected with upper feed pipe, lower confession The water outlet of water pipe is located at the bottom of hatchery；On stent, be also equipped with spray head above each hatchery, spray head with Upper feed pipe is connected or is connected with the lower feed pipe positioned at internal stent.Such setting need to use indoors, it is impossible to perfect The environment of Odontobutis obscura existence is simulated, hatching effect and not economical and practical enough may be influenced.
