Several key aspects of tilapia cage culture
. First, pay attention to the Taiwan joint density q box; accounted f · 』feed to prevent vitamin deficiency. . , '7 '* 7 /, accounting) 0 feeding techniques: Kennedy is scheduled to vote a special four-bait. With the increasing appetite to eat. Cage culture of tilapia fed on text wrap = times since May by several key aspects of Polygonum posumbu II;,, {r feeding tilapia strong poison fed Times New Arrivals Glass l Head should be controlled on the left for 20 minutes , water closure of water, the flow rate of 6 beam _ / boat bell is appropriate, pools 5-8 m, water fresh, quality deer, conveniently, easy to manage. 2. fingerling size and density: the best non-fish stocking master Hang two specifications: one is 150-250 g / tail, a density of 100 / beam or 2ok8 / end. Aquaculture 60 days, the general end-loaded about 600 grams can be had l the other is 75-150 g / tail, density of l00 ~ 120 fry / beam or l ~ ke / Cambodia, about 120 days of culture, specifications can be had 500-600 g / tail, the two get better Jieneng the most urgent economic Ju same specifications with the membership to be tidy. II , well-placed well 1. cage before stocking in the water for 3-5 days, shipped the day before the fish starved for membership, cooling up to around 18 ℃, as soil and naturalization before and after the temperature 2. riding a process of continuous charge transport oxygen or oxygenated plastic bags with a ride, into the box before the pheasant with lOppra alkaline disinfection for 10 minutes. 3. disinfection bags into the box after the setback, the method is diagonal l dwarfish, each containing 200 grams of chlorine net or fish excellent chapter Coupling for three days. lookg fish weight at the same time, mixed with 5 grams or oxygen Hong ADM ADM bait, and even cried for five days 4. pre-acclimation of feeding. feeding abundance by 1-2,uggs bestellen, then according to feeding conditions. Lan, strengthening management of feed 1 feed requirements well: with the stars expected feed requirements of nutrition Kui face severe fresh taste, g sub-thorn in the local feed resources, affordable and fast as the growth of tilapia, the cycle is short, some reservoir valley rain abundance water can not be mixed feeding for several days, so seize the opportunity, strengthen training, dietary protein content is relatively higher. feed formula roughly as follows: Secretary-General of fish meal 8,ugg boots billig, yeast 7, JH-l 5, animal protein, beans, Park 25 , 7, cottonseed cake, maize lO, find the skin 26,north face outlet, 10 Brewer salt 2, multi-dimensional element o.2 crude protein content is 32 units, feed around 2 deposited in the Department of. feed at least once a week, fresh green oxygen tank, may be a small amount of feeding, storm large, muddy water when the feed in order to prevent waste, to be indigestion. d 'improve prevention and treatment of fish diseases in recent years, a continuous tilapia} Jiyou a disease outbreak, the main disease is blind, congestion, ulceration , termite Jing, understand the Ministry of swollen lungs with yellow water. liver was yellow and white clip purple lesion, for the brave. group total shallow, box twist around the rim like the white shoes Yi will. swimming turn heir. onset temperature of 25 -33-c, Wong disease of long duration, usually 6-9 month near, the peak period of June to 8 Yuan month. harm fish size in the 150-750 grams, 200-500 grams in more than deposited, more harm large. death for 20 low-abundance, higher than the 40-6n, a cut 3O 6O. pathogenesis is thought to caused by a variety of combination of factors, the analysis may have the following objectives disease: one had a box of fish density too much or unreasonable layout. The second is the lack of certain vitamins in feed, or some nutrients into lean, resulting in reduced resistance to disease. Third, persistent drought and high temperatures, causing water quality deterioration. Fourth, the external pathogen invasion. Fifth, Henry the long-term non-child Since the case of self-education, character degradation, decreased resistance to disease. has not been determined, do not report the same temporary name for the non-fish cage culture Hang Hang non-fish immune syndrome or disease lack sensitivity. the main control measures: ① control density. a stocking density does not take more than 120 / at the end is appropriate, too much surface area ratio with the same beat big 200f1, with box spacing, row spacing rational layout. ② regularly hang the bag, feeding bait. monthly shoes two persons, each excellent oxygen tank with 200 grams net, child safety and may choose to feed the last meal of the Queen, in case of ingestion. while mixing feed bait, erythromycin or chloramphenicol,ghd outlet, anti-use capsule 3-5 {g / lOOkg Children , the treatment dosage of 5-8 g / lOOkg fish, fish blood, scattered, preventing the amount of 50 grams / lOOkg fish, treatment dosage of i00 g / lOOkg fish, and even fed 3-6 days for treatment, the two month course of treatment. @ periodic Yao voted green fodder. fed at least once a week to duckweed, fresh leather based,ghd nederland, choose the last meal feeding.
