Dirt operation, second is that preventing small dimension fish etc. from slipping through the net.
Production operation
1, it investigates
The first-hand data with the relevant cultivation of the big water surface is grasped, determines kind, density, collocation of cultured fishes etc..
2, it builds and builds aquaculture pond
Determine that cultured area, selection cultivation place design pond structure, specification, bottom of pond, anti-escape network, integral layout etc.,
Block builds aquaculture pond.
3, oxygen increasing equipment and auxiliary facility are installed, ensure the normal operation of water cycle.
4, seed selection and dispensing in cement pit
After above-mentioned work completion, seed is selected according to market situation, the specification of the seed of general fish be 50g/ tails~
Net cage can be arranged in cement pit, cultivated in net cage if seed size is less than normal for 200g/ tails, appropriate rule to be achieved
After lattice, places into cement pit and cultivated.Cultivation density is generally 75 tails/m3~150 tails/m3, specific cultivation density will be according to foster
Plantation technology qualification, cultivating condition, breed variety are flexibly grasped.
5, the seed of the big water surface is launched
During industrial aquaculture, there is part organic granular that can enter the big water surface, at this moment can be put in the increasing of the big water surface omnivorous
Property, filter-feeding fish specifically puts seedling density and specification is not unified such as carp, Tilapia mossambica, crucian, mullet, variegated carp, silver carp
It is required that be adjusted according to the water quality of the big water surface, cultivation scale, technology, sale etc..
6, bait feeding
The abundance of food is fed in order to accurately grasp, reduces water pollution, it is proposed that feed puffing bait, feed 7 times~8 daily
Secondary, each feeding volume is that fish 6 divides~8 points to satisfy, and can feed grope with reference to related data by measuring weight, from
And find suitable bait feeding quantity.
7, micro-pipe or gas exhausting stone or the oxygenation of gas exhausting stone beam and water recycle
Booting oxygenation in 24 hours will observe flowing velocity of the bait in recirculated water, prevent bait mistake in bait feeding
Early outflow feeding area, it may be necessary to adjust oxygenation tolerance, increase bait feeding number, reduce each Feeding time.
8, disease control
It reduces the destruction to big water surface water environment to the greatest extent, ensures the ecological environment of the big water surface, it may be necessary to pass through pharmaceutical chemistry
Or the diseases such as additive of bait prevention fish.
9, blowdown
Remaining baits, the excrement such as cement pit is interior, sewage sump is interior etc. are exhausted in time, reduce organic matter as far as possible in the big water surface
Accumulation.
10, daily management
Situations such as running check anti-escape network, oxygenation facility；Often observation fish movement situation, water quality situation；Often listen to
Weather forecast and understanding periphery cultivate situation, timely solution of pinpointing the problems.
