Requirements for Shrimp broodstock farm bulding

Technical requirements for site selection, design & construction of breeding shrimps

1. Selecting location for shrimp bonds:
Selection of camp site was one of the important factors for future camp activities. To maximize the capacity of the camps with the highest efficiency required the selection of location to build camps satisfy some basic requirements as follows:
– Location and construction site:
– The location of the camp can be located on the coast, in the bay, on the islands or in the inland so that it can be ensured of saltwater. On the other hand, the farm must be located on high land that can avoid large floods or tides every year.
– The water and soil environment is not polluted by industrial and agricultural waste such as chemicals, petroleum, heavy metals, pesticides …
– Water and water resources:
– Salt water:
Saltwater is the decisive factor for the entire production process of the farm. As a result, saltwater supply is not polluted, which can be taken directly from the sea, from the underground, from salt fields. However, sources of water derived from underground aquifers, although their chemical and physical standards are stable, still have an inferior quality indicator of infertility that exceeds the allowable thresholds compared to the requirements of the hatchery. Therefore, want to use is required to process more complex, the volume of settling tanks, the level must be increased to 3 times the normal, increase production costs. However, when using groundwater with good water treatment process, it will be more advantageous in term of stable production. Therefore, in order to select the location of the hatchery to be surveyed, the best source of water must meet the following criteria:
– Salinity of water:> 28 ‰.
– Water temperature: 25 – 31 degrees Celsius
– pH: 7.5 – 8.5
– Heavy metals: <0.01 mg / l
– NH4 + – N: <0.1 mg / l
– NO2 – N: <0.01 mg / l
– H2S: <0.1mg / l
1.2.2 Fresh water:
Although there is no decisive element in production, good fresh water resources will be more favorable to sanitation after each production, for domestication and reduction of salinity of shrimps when necessary. Therefore, fresh water can be used as tap water, well water and good ground water.
The best fresh water standard is the water standard for normal living.
1.3 Some other requirements.
1.3.1 Sources of larval supply (Nauplius)
In order to ensure continuous production, hatcheries need to be active in supplying larvae. Therefore the hatchery must:
– Near the production base, supply larvae.
– Actively raising shrimp for parents. Brood stock broodstock can be harvested from wild broodstock or egg-free broodstock, capable of broodstock and spawning.
1.3.2 Power source:
The hatchery must be close to the grid source to ensure smooth, continuous production, low production costs. On the other hand, there should be more oil-fired generators or compressors to take the initiative in making room for blackouts.
1.3.3 Traffic:
Can use convenient transportation such as ships, cars … to bring the shrimp brood stock, larvae come and transport shrimp Sroodstock.
2. Design and construction:
The requirements for the design of the hatchery depend on the scale and capacity expected to be initially designed to be suitable.
At present, there are many types of shrimp hatchery model designs along with many different types of materials:
– The broodstock, larval rearing tank can be designed in rectangular, square, circular and conical forms. With different materials such as composite, concrete, brick and plastic. And volume from 3 – 50 m3
– The scale of the camp also has a very large volume change from 60 to 1000m. However, through the practical process to easily achieve high efficiency in conventional production management, conventional hatchery production farms are designed according to the family size with a capacity of 10-15 million PL15 / male. Therefore, in this document we only introduce the design of a single shrimp breeding farm from broodstock to PL15 with a capacity of 10-15 million PL15 per year is widely disseminated. It has been proven effective over many years of experience.
2.1. Basic construction works:
– Requirement of sealing, waterproofing works.
