Breeding pangasius.
Breeding of fish of patin [is] usually [done/conducted] with technique marry to inject because mains of patin [do] not [is] influenced. to [be] prolific if/when with natural environment. Technique Breeding of induction ( breeding induce) by inseminating gland condensation of hipofise mixed with ovaprim. Usually, this technique [is] followed with sequence technique ( stripping) [so that/ to be] castaway egg [do] not and can be incubated in aquarium.
Pool construction.
Pool Mains of Pangasius separate located masculine usually with mains pool of Pangasius female. If/When is not available enough pool, usually only provided [by] pool for just female mains. easier Masculine mains searched to farmer of fish compared to readily female mains lay eggs.
good pool usually in form of is square [of] length because more is guarantying [of] sirkulasi irrigate and water down arrest with net. Pool better obtain;get pasokan irrigate from channel inclusion of direct water, non from other pool. [The] mentioned aim to to avoid influence of disease [pass/through] water of fish which [is] infection. Besides, pool better have perfect dismissal door in form of monik ( construction of outlet pool ) to facilitate draining of pool water during quickly.
Preparation.
For the breeding of pangasius with technique marry to inject, have to be drawn up [by] donor in the form of matured goldfish [of] genitals. Usually, donor weared [by] [is] masculine goldfish because easier obtain;get matured male [of] genitals compared to matured female [of] genitals, besides because economic reason. food for seed also have to be drawn up. food which in the form of lilliputian prawn [of] Daphnia incubated in place of hatch in the form of given [by] gallon [is] hole basically and placed in inversed position.
Breeding.
Breeding of fish of pangasius usually pass some the following activity a. Heavy enumeration [of] donor Generally is, female [of] pangasius given [by] 3 dose. Therefore, to 5 female mains singk [of] pangasius, donor which must be drawn up [by] counted 15 singk. [For a] while for masculine mains which only 1 dose so that require to be drawn up [by] donor as heavy as 5 singk to 5 masculine mains singk. Become, to once execution of Breeder of fish of patin as heavy as 5 singk, required [by] goldfish as heavy as 20 singk as donor. If/When donor goldfish mean which have matured genitals as heavy as 0,5 singk hence there [is] [about/around] V tail which must be cut [by] head and taken [by] its gland [of] him.
Intake of gland of hipofise.
This activity [is] [done/conducted] by cutting is athwart [of] goldfish head so that separated from its body. Hereinafter, trap goldfish confronted to to the to be cut lengthwise start from nostril. Ex- this last slice will show brain which [is] white chromatic follow apartly, Afterwards, the brain carried over [by] paper filter with blood remains and pinset and also fat cleaned with cotton. After cleanness, will see gland of hipofise white chromatic equal to item of merica ( 1-2 mm) which located in elementary hollowing [of] skull bone.
Making of gland extract.
Making of gland extract [done/conducted] [by] After all gland of hipofis,4 taken away from [by] donor fish skull. The gland have to be cleaned on paper filter. Later;Then, gland [entered/included] into destroyer glass and enhanced [by] akuabides [among/between] 1,5-2 cc for the setup of kilogram of[is amount of mains to be injected. Dirt can be precipitated by condensation [entered/included] into centrifugal ( turn around ), both for electrical and also manual.
Inoculation.
Inoculation [done/conducted] [by] after homogeneous condensation which [is] transparent locked out of [by] gland sediment by using spuit ( injection appliance). Inoculation of [done/conducted] [by] female mains 2 times [so that/ to be] is effective, while for just iantan enough once. First inoculation [is] usually [done/conducted] at 18.00 counted dose i [at] female mains. [both/ second] Inoculation [done/conducted] after 12 [hour/clock] of first inoculation that is at 06.00 counted 2 dose [at] female mains. As for masculine mains injected at the (time) of inoculation both [of] female mains. Inoculation [done/conducted] [at] flesh muscle part of back ( intramusculler), precisely rear back fin [about/around] parallel third or [both/ second] line with part of genitals. Injection needle with inclination of WO of back direction in 1-2 cm. After injected, both mains reentered to place relocation of each mains.
Stripping ( sequence). Sequence [done/conducted] [by] after 10-12 [hour/clock] of injection both. left holded Female mains by hand [in] part of right hand and back [in] part of stomach. Whereas right hand thumb massage berulangulang [at] part of stomach up at release hole. Egg accomodated in clean baskom which given [by] a few/little water. In the same way sequence [done/conducted] [at] masculine mains. After exit, sperma mixed with egg and swirled [by] slow with quill during 3-4 minute. Egg which have been mingled [by] dilution of sperma [is] later;then rinsed with clean water to eliminate the rest of dilution of sperma, feses, and blood.
