. Provision of Seed .

. Provision of Seed .Seed supply business ( milkfish ) continuously with good quality made ​​with intensive hatchery systems in special ponds , maturation ponds are holding , spawning , and ponds peneneran pembsaran . In milkfish hatchery steps taken are :1 . Election superior parent . Superior parent will lose their properties to their offspring , Characteristics :- Normal shape , length and weight ratAgen Bola Terpercayaio is ideal .- A relatively small head size , among the fastest growing uterus .- Arrangement of scales on a regular , smooth , shiny , no injuries .- Agile and normal movement .- Aged between 5 years 4 .
2 . Stimulate spawning . Gonadal maturation can be accelerated with the use of hormone LHRH ( Letuizing Hormone Releasing Hormone ) by injection . '
3 . Breeding . Spawning is mixing the male parent and Berina mature sperm cells and egg cells that occurs expenditures ( ejaculation ) of the second cell . After being in the water , sperm will fertilize the egg for fertilization systems of fish occurs outside the body . Spawning is performed in a special pond spawning
4 . Hatching . Eggs that float in the pool spawning hatch after 24-26 hours of the start of spawning . Egg will hatch into larvae that still have food reserves of the parent egg yolks , so do not need to be fed until the age of 2 days .
5 . Caring seed . After 9 days old larvae were transferred to an nener maintenance . In this pool of larvae fed natural plankton . Growth of plankton by fertilizing and liming done . Proper fertilization with manure is a TON ( FARMS ORGANIC NUSANTARA ) containing various mineral elements essential for the growth of plankton , such as N , P , K , Mg , Ca , Mg , S , Cl , etc. , are also equipped with humic acid and vulvat mempu improve texture and increase soil fertility bottom of the pool with a dose of 5 bottles TON / ha or 25 g ( 2 tablespoons ) / 100 m2 on each water intake . Time peneneran 8 weeks . Feed given in the form of flour with a protein content of 30 % . To add a feed to feed nutrients pencampuiran NASA with a dose of 2-5 / kg of feed is necessary , because NASA contains essential mineral elements , namely N , P , K , Mg , Fe , Ca , S and others , vitamins , proteins and fat to improve the health and growth of milkfish fry .
IV . Enlargement .
Pulau TidungHaving maintained in an peneneran for 8 weeks , milkfish transferred to rearing ponds . Technical enlargement banding include a few things , namely :1 . Preparation of land .This stage is done before the water inlet . activities carried out during the preparation of the land is :
