Many are interested in grouper fish farming as it adds to the source of livelihood of mostly all poor families. This kind of farming is easy to be maintained which nearly attracts the attention of people. If you are one of those people interested in this business, this article can guide you.
 

Site Selection
 

Choosing the best site has its significant role to play when starting grouper fish farming. Provide a net cage that must be situated in areas with adequate water and water quality, no predators, and likewise protected from strong waves and wind. Considerable planning and thought must go well into choosing sites for grouper fish farming. The cost and ease of operation should be planned properly before getting in the way of the business.
 

Polyethylene materials and bamboo poles are popularly constructed which are now called floating cages. They must be provided at exactly twenty-five to fifty millimeters, in diameter. In forming the net cage, there must be two kinds of panels: one bottom panel and four side panels that form the water on the net cage. Also, the net must securely fit on the raft structure or bamboo poles through the use of ropes.

The bamboo can be held together by a structurally-built rope system from which the nets will be attached. With empty gallons entirely attached on the bamboo frames, expect that buoyancy is likewise provided.
 

Feeding the Grouper Fish
 

After getting through with the site selection, feeding the grouper fish is a must-thing to consider in this farming. Since groupers are classified as carnivorous animals, they must consequently be fed with feeds rich in fish protein. Most farms situated in Asia rely on trash fish. However, other alternatives include fish sauce and human food that can contribute to a more productive grouper fish farming. It is required to feed them once or twice in a day, with total biomass.
 

Apart from trash fish, tilapia fingerlings must be given to grouper fish at five percent. Give them the daily requirement needed earlier in the morning, while other half to be given in the afternoon. Place the fingerling on a tray and monitor it as well. Additionally, determine the feed requirement and biomass of the stock for monthly sampling.
 

Monitoring
 

In addition to how to start grouper fish farming, monitoring is still one thing to consider. Always monitor the parameters of the water: water temperature (24-31 degree Celsius), dissolved oxygen (4.9-9.3ppm), salinity (21-41 ppt) and water depth (1.0-1.3m).
 

Harvesting
 

The most exciting activity in this farming is harvesting. Selective harvesting must be done wherein the size of grouper fish must be at exactly 400-600g. Place a drag net on the southern end part of the site while you drag it slowly on the other end in the morning. Grouper fish must be transferred in the net wherein the grading is done, however, undersized fish must be thrown back in the pond.
