Embodiment
A knurl dog whelk seedling-cultivating method, has the steps such as collecting fertilized eggs, hatching, larvae cultivation, juvenile mollusk cultivation.
1, collecting fertilized eggs
Adopt the employing of ovum adherance and take corrugated plating as bottom, then with corrugated plating, as sidewall, surround the drum-shaped of diameter 70～80cm, and put into stone, add water, inflation.In each drum, put into 3 kilograms of close spiral shells, approximately 300/m
2.After approximately one week, start to have oopod output, oopod average length 1.2cm, diameter 0.2cm, every close spiral shell on average produces 25 oopods, approximately has 200～300 fertilized eggs in every oopod.
2, hatching
Hatching naturally in pond, the cultivating process after this also seawater under natural temperature carries out.
3, larvae cultivation
At the knurl dog whelk seedling culture initial stage, seawater water temperature is 20 ℃ of left and right, to 8, September ocean temperature between 23～25 ℃.
Wherein bait feeding method is between the pelagic period, to take chrysophyceae as main bait, is aided with chlorella, flat algae and Chaetoceros, to increase the rich of its nutrition.Wherein D shape phase bait feeding amount is 2000/ml of chrysophyceae left and right, and each 200/ml left and right of chlorella, flat algae and Chaetoceros is progressively increased to 5000/ml of chrysophyceae left and right, each 500/ml left and right of chlorella, flat algae and Chaetoceros; Treat approximately 5000/ml of shell top phase chrysophyceae left and right, each 500/ml left and right of chlorella, flat algae and Chaetoceros is progressively increased to 8000/ml of chrysophyceae left and right, each 800/ml left and right of chlorella, flat algae and Chaetoceros.At settlement and metamorphosis phase bait, start to turn to animal bait by vegetal bait subsequently, bait feeding progressively changes to 5000/ml of chrysophyceae, every 30m3 water body hello 10g prawn slice (prawn slice sieve with 250 order nets), razor clam meat 100g(with meat grinder rubbing from 8000/ml of chrysophyceae, every 30m3 water body hello 5g prawn slice (prawn slice sieve with 250 order nets), razor clam meat 0g during this time, then sieves with 250 order nets).
Wherein pond water changes twice every day, changes water more than 1/3 at every turn, depending on water quality situation, determines, generally reaches ammonia-nitrogen content in water and, below 0.2mg/L, within every three days, falls pond once.
4, juvenile mollusk is cultivated
