Description

Long body is intended the manual work of flat tooth goby and is tamed and dociled the food method

[technical field]

The present invention relates to long body and intend the tame and docile food method of flat tooth goby, particularly long body is intended the artificial food method of taming and dociling of flat tooth goby.

[background technology]

Long body is intended flat tooth goby, latin name: Pseudapocryptes elongatus, and be under the jurisdiction of goby suborder (Gobioidei), goby section (Gobiidae), intend flat tooth goby genus (Pseudapocryptes), be commonly called as Vietnam pigeon fish.It is the water warm small fishes that long body is intended flat tooth goby, inhabits river mouth degree of saltiness water and offshore beach place, also lives in the downstream river freshwater.It is bright in luster that long body is intended flat tooth goby, and exquisiteness Fresh & Tender in Texture is one of traditional cuisines of Asian countries such as China, Japan, Thailand, Vietnam.But tradition is cultured long body and is intended flat tooth goby, is staple food with benthic diatom and organic debris only in its process of growth, and the elementary idiosthenia of the algae in the beach pond is very limited, and inanition has seriously restricted the raising that long body is intended flat tooth goby cultured output.Therefore, press for a kind of can directional transformation long body and intend flat tooth goby eating habit, tame and docile food technology, equal the cultured output of tooth goby to improve long body plan, so that large-scale farming based on the ingest manual work of pellet of feeding habits transformation mechanism domestication adult fish.

[summary of the invention]

Goal of the invention of the present invention provides a kind of can transform the flat tooth goby eating habit of wild long body plan; Carrying out the tame and docile nourishment maintenance of manual work grows, makes it to cooperate artificial feed; Intend the cultured output of flat tooth goby to improve long body, the long body of being convenient to large-scale farming is intended the artificial food method of taming and dociling of flat tooth goby.

Make eye bright for reaching above-mentioned, the technical scheme of employing is following:

Long body is intended the artificial food method of taming and dociling of flat tooth goby, may further comprise the steps:

Prepare in a, cultivation pond: cultivation is an argillo arenaceous at the bottom of the pond, pond, area 1800～3000m ², water inlet mid-May, the depth of water is controlled at 0.2～0.5m, and salinity is controlled at 5～15 ‰, and water inlet is filtered through 120～150 mesh sieve tulles; After the water inlet, by 1.5～2g/m ³The 90% crystal chlorophos of splashing, behind 48～72h by 50～60g/m ³Splash with the tea bran of pond water logging bubble 8～12h; Having splashed splashes in the 1st fine morning behind the tea bran soaks the biological compound organic fertilizer of 2～4h in advance, and usage amount is 15～25g/m ³After the fertilising, arrive fine weather whenever first, press 1.5g～7.5g/m the morning ³Consumption topdresses, and is controlled at 15～25cm up to water transparency, sunlight can not the direct projection pond at the bottom of;

B, anti-escape net setting: cultivate pool side 0.5～1m place in distance; Whenever insert 1 bamboo pole at a distance from 3～5m; Bamboo pole 45 °～60 ° angles that tilt to the inside are fixed on to make on the bamboo pole with 10～20 order polythene nets and anti-ly escape net, prevent the fry that fry flight and unfirmly closing food pull in to shore;

C, fry are put in a suitable place to breed and tame: late May was bought long body and intends the flat wild seedling of tooth goby, by 70～80 tails/m to early June ²Put long body in a suitable place to breed and intend flat tooth goby seedling, body length is controlled between 2～4cm, and the fry total length must not surpass 4cm, eats successfully otherwise can't tame and docile; Fry went into behind the pond 1～2 day, did not throw any bait; Since the 3rd day, escape to net the inner edge uniform eel feed powder of blunging of throwing something and feeding along anti-, day throw something and feed 3～5 times, each 0.4～0.5kg knocks animal feeds bucket with wooden stick simultaneously, forms the sound conditioned reflex; Whenever stopped to throw something and feed 1 day at a distance from 3 days; Powder is tamed and dociled food and is continued after 13～15 days, and the fry that ingests when come-up surpasses fry sum 80%, and the fry average body is grown up when 7cm; Improve cultivation pool water level 0.05～0.1m every day and be controlled at 1.5～2.0m up to water level; In 10%～15% ratio the eel feed powder is replaced to No. 0 expanded pellet feed of marine fish gradually fully simultaneously, No. 0 expanded pellet feed nutrient ingredient requirements of marine fish protein content>=40%, fiber content>=6%; Fat content≤8%; Content of ashes≤16%, moisture≤11% is tamed and dociled food and is continued 30～40 days;

D, fry are formed: tame and docile food through 30～40 days manual works, can accomplish long body and intend flat tooth goby and transfer the eating habit domestication of manufactured feed of swimming of ingesting to by the benthic diatom that ingests; Cultured 55～60 days, 20%～25% ratio of per diem replacing replaces with No. 1 expanded pellet feed of marine fish, its nutrient ingredient requirements protein content>=35% with No. 0 expanded pellet feed of marine fish; Fiber content>=6%; Fat content≤6%, content of ashes≤14%, moisture≤11%; Cultured 75～80 days, 20%～25% ratio of per diem replacing replaces with No. 2 expanded pellet feeds of marine fish, its nutrient ingredient requirements protein content>=30% with No. 1 expanded pellet feed of marine fish; Fiber content>=7%; Fat content≤5%, content of ashes≤12%, moisture≤11%; Cultured 90～95 days, 20%～25% ratio of per diem replacing replaces with No. 3 expanded pellet feeds of marine fish, its nutrient ingredient requirements protein content>=26% with No. 2 expanded pellet feeds of marine fish; Fiber content>=7%; Fat content≤5%, content of ashes≤10%, moisture≤11%; Cultured 115～120 days, 20%～25% ratio of per diem replacing replaces with No. 4 expanded pellet feeds of marine fish, its nutrient ingredient requirements protein content>=22% with No. 3 expanded pellet feeds of marine fish; Fiber content>=8%; Fat content≤4%, content of ashes≤10%, moisture≤11%; Cultured 135～140 days, 20%～25% ratio of per diem replacing replaces with No. 5 expanded pellet feeds of marine fish, its nutrient ingredient requirements protein content>=18% with No. 4 expanded pellet feeds of marine fish; Fiber content>=8%; Fat content≤3%, content of ashes≤10%, moisture≤11%; The flat tooth goby of long body plan is formed and throws something and feeds process day 2～3 times, and day feeding rate 3～5% is formed process and need do not changed water, and through 150～160 days, specification can reach 45～50 tails/Kg, and output can reach 1～1.5Kg/m ³

Advantage of the present invention:

The invention solves long body plan and equal tame and docile environmental condition, tame and docile choose opportunities, the tame and docile key issues such as feed nutrient, fry eating habit transformation regulate and control method of eating of eating of eating of tooth goby; Can significantly improve long body and intend flat tooth goby breed efficient, significant to the intensivization development of China's beach fish culture industry.
