Handling and transportation of tilapia fingerlings is a process that needs to be carried out with utmost caution. A large number has to be hauled and put in the appropriate water quantity. If this is not done appropriately, it is likely that the mortality of the fingerlings will deteriorate. If you are starting a tilapia farm, there are a couple of things you need to take into consideration to ensure that this end is met.
Prior to the day of transportation, you have to precondition them. This is something that most people tend to overlook as they start tilapia farming and yet, it goes a long way to determine whether one succeeds or not. The fingerlings have to be placed what is known as “hapa” or concrete tanks which are aerated for a maximum of three days from the brood pond or nursery. This prepares them for the change and also ensures that they are better prepared for the handling stress which is witnessed during harvest time. During the conditioning process, the fingerlings should be fed but this should be stopped 24 hours to disposal.
Always make sure that there is no overcrowding in the “hapa” and especially during the mornings when the oxygen levels tend to be low. When you note they are coming up for aeration, this should be an indication you need to decrease the rate. This is something important to keep in mind since it can help you with maintaining your tilapia farm.
Once you have decided to indulge in Tilapia farming, it is important to note that there are different ways of transporting them to your fish farm. Some of these include the following.
- For starters, you could use some plastic bags. These come in different sizes and while this is the case, the ones popularly used to transport fingerlings are 20 inches by 30 inches by .003 of double seine glaze. The fingerlings transported in these should be of size twenty two and the bag should hold at least 400 pieces. This should ideal for long distances though the time limit should be twenty four hours. For shorter distances, you can transport up to eight thousand or ten thousand but for less than 6 hours. The temperature should be maintained at 280 C to 300 C.
- Tank or hauling box: These should be made from aluminum sheet, metal sheet, stainless sheet or fiber glass and it should be designed in a manner that can hold water. The capacity should be 0.18 to 0.24.
Once you learn how to handle and transport fish, you will set up a successful tilapia farm.
