Dalian, where the sale of specific products scallop farming

Agriculture and Fisheries em Beverly use instead of disinfectants and antibiotics bacteria can not only save costs, improve quality and productivity scallop seedlings, but also can reduce the pollution of the marine environment, and to minimize emissions, to achieve pollution-free health concept farming. Dalian seafood farms in Liaoning Province Fisheries em use of agricultural Beverly bacteria were scallop artificial breeding, and achieved good results: First, the preparatory work before nursery products microecological ⑴ sources and preparation ⑴ EM species: Buy Zhengzhou agricultural Beverly Biological Technology Co., EM aquatic species, a composite of photosynthetic bacteria, yeasts, Bacillus seven categories of more than 80 species of bacteria from. Yang EM liquid bacteria: 1: 1: 10 (1 bottle species: brown sugar 1 kg: 10 kg of water) ratio of vaccination, general culture about a week feeding density can be achieved.

Broodstock into the shop a month ago three vaccination, pre-primary cultured N. closterium late to cultivate Zhanjiang Isochrysis mainly cultivate according to one cubic meter of water 0.5 m3 of water to do food preparation. ⒊ fertile scallop pro 贝培 ⑴ sources of broodstock: broodstock available from Changhai County, Liaoning Province, the sea, the cage shellfish, individuals in more than 10 cm, according to one cubic meter of water two females are to be prepared. ⑵ the ripening broodstock: broodstock shipped from the sea after the first 5 days of culture in natural seawater, natural seawater to 4 ℃. Then rose to 4.5 ℃, cultured for 5 days, then rose to 5 ℃, cultured for 7 days. 5.5 ℃, respectively cultured 6.0 ℃, 6.5 ℃ when five days, rose 7 ℃ constant temperature. Bait feeding three days before adding 10 (parts per million concentration) photosynthetic bacteria. While feeding the right amount of egg yolk, milk, marine red yeast as a broodstock nutrition supplement. ⑶ spawning: After 35 days of ripening cultivation, broodstock gonadal already mature, absorbing bottom examination found the eggs, the broodstock dry 1 hour, 9 ℃ into the water, 40 minutes after the start of spawning, Spillers the right amount of spermatozoa and fertilization. Eggs hatch density is 20 per milliliter, trace inflatable, stir every hour, 84 hours after the larvae develop to the D-type.

In various nutrient indicators, the level of nitrate nitrogen content plays a leading role, which affects the development of scallop larval metamorphosis, larvae and even cause death, resulting in artificial breeding failure. By the bait into aquatic bacterium em, some nutrients can be absorbed and used, but also can be as a kind of bait scallop larvae feeding, em bacteria photosynthetic bacteria in vivo protein and have a high content of various vitamins and rich The lipids, non-toxic, easy to digest. Em aquatic bacteria not only help to maintain good water environment, while the broodstock and larvae is also a good source of nutrition. ⒉ aquatic EM bacteria for use on larval rearing in the indoor artificial breeding, the biomass unit of the body of water is very intensive, produce large amounts of waste during their metabolism, dead larvae and unicellular algae decompose, easily lead to ammonia in seawater concentration, total ammonia concentration and pH change significantly, resulting in an increase of undissociated ammonia. Undissociated ammonia no charge, but has a higher fat-soluble, easily through the cell wall, causing harm to the larvae, resulting in artificial breeding failure. After a day changing the water into water to cultivate aquatic agricultural Beverly EM bacteria, can effectively regulate water quality. EM bacteria in aquatic photosynthetic bacteria, Bacillus, etc. can effectively break down organic matter, reduce the amount of ammonia, hydrogen sulfide. Large population of beneficial bacteria, can form the population advantage, inhibit other pathogenic bacteria causing rot propagation generation, to disease prevention purposes. Agriculture and Fisheries Beverly EM bacteria also excellent scallop larvae feed its growth and development is very useful.
