Murrel Fish Farming
Murrel fish is a water fish that can be grown substantially in a small farm. This farming can supplement high revenue on the part of a small farmer. It also serves as an alternative to many farmers in order to avoid other pollutants and mercury that can affect the lives of murrel fishes.
Raising these fishes is never a hard task as it only requires hard work and commitment.
Murrel fish farming is familiar in cultured countries such as Taiwan, Philippines and Thailand. This kind of farming tremendously offers opportunities not only to farmers but to unemployed and poor youths. In this farming, there are requirements that a farmer must follow to grow murrel fishes abundantly.
Land that Meets Murrel Fish Farming
Among the requirements set in murrel farming, the land must be considered a number one priority. It must meet two of important standards: the pond must possess good-quality water and must be positioned above the plain. Metabolic wastes should be removed from the land as murrel fishes can be grown and safely stocked at a much higher density. A low land is also required as the soil can hold water compared with an urban area that must first be converted in fish farming.
Pond and Size Construction
Apart from the land that should be prepared, also pay attention to the size of the pond. Remember that the amount of murrel fishes that can be raised will depend on its size. Never plan to overcrowd the pond as it can entirely affect their lives. A large pond will require many fishes that can adapt into it.
On the other hand, the pond must be constructed suitably for excellent murrel fish farming. An earthen dyke should entirely be built in order to retain water and hold fish. The estimated height for the dyke is between fifty to one hundred cm that may depend on the topography and tidal amplitude of the land. It is also necessary to provide a perimeter canal where the water comes out. Apart from the perimeter canal, cross trenches must be constructed in opposite directions. The lower part of the trenches should be placed above the canal in order that the entire water can be removed during the desalination.
Drainage and Water Supply
For an effective drainage, a feeder canal is provided in order that the water flow can be regulated. Sluice gate must fit on the wooden shutter and be placed at 30cm height of the plot. Another sluice can be used in draining out water from the plot down to the feeder canal. This can be placed during low tide for drainage, desalination and water exchange. On the exit and entry mouths of the gate, wooden shutters are placed to be able to regulate water movement.
Water Temperature Control
Additionally, the water temperature in the pond must be controlled to produce more murrel fishes that cannot be grown in a geographic area. It further provides optimum growth and maximizes food conversion. A maximized production is expected to occur in the entire year that allows rapid income since fish can be provided in each week.
