The main problem of tilapia fish farming is it’s unconditioned propagate. As a result we can see different aged and sized tilapia fish in the pond and we can’t get desired production.

Naturally male tilapia grows rapidly than female. Separating the male tilapia and raising them separately is called monosex tilapia fish farming.

A pond with 1.5 to 4 feet depth is ideal for monosex tilapia nursing. Consider the followings while selecting nursing pond.

  • The pond must have to be free form flood.
  • Sufficient amount of sunlight is very important.
  • The pond must have to be free from all types of harmful aquatic weeds.

Nursing Pond Management

Nursing pond management systems for monosex tilapia farming are shortly described below.

  • First of all remove water from the pond and make it dry. If it is not possible to dry the pond, use medicines or chemicals for eradicating cannibalistic and unwanted fishes from the pond.
  • After that apply 100 kg lime, 500-700 kg dung, 10-15 kg urea, 5-7.5 kg TSP and 2 kg MOP per acre.
  • Prevent entrance of frog, snakes and other harmful predators by making a fence with net surrounding the pond.
  • After 5-7 days of applying fertilizers, stock 21-28 days aged monosex tilapia in the pond. Stock 100000-200000 monosex tilapia minnow per acre.
  • Apply highly protein enriched (about 35%) feed at the rate of 10-15% of the body weight of total stocked fish. For example if you stock 100 kg fish in the pond then apply 10-15 kg feed daily. Don’t serve all the feeds at once a day. Instead serve the feed 3-4 times a day. Raise the fish in this system for 40-60 days and after that transfer them to stocking pond when each fish weights about 20-30 grams.

Stocking Pond Management

The stocking pond management systems are shortly described below.

  • The depth of stocking pond may vary in accordance with your location. There are no problems if the depth of stocking pond become more than nursing pond.
  • Remove all types of cannibalistic and unwanted fishes from the pond by drying, pulling net or using medicines or chemicals.
  • After that apply 100 kg lime, 500-700 kg dung, 10-15 kg urea, 5-7.5 kg TSP and 2 kg MOP per acre in the pond.
  • After 5-7 days of applying fertilizer, natural fish feeds will automatically grow in the pond. Stock 20-30 grams body weight fish in the stocking pond that you have raised in your nursing pond. You can stock 20000-25000 fish per acre.
  • To ensure natural feed in the pond you can apply 400-500 kg dung, 200-300 kg chicken excreta, 3.5 kg urea and 2 kg TSP per acre after every seven days. Stop applying fertilizer if you feed your fish supplementry fish feed.
  • Try to change the water of pond daily at the rate of 5% when the fish reach more than 100 grams body weight. Doing this will make good result in total production.
  • Monosex tilapia reach 200-250 grams body weight within 100-120 days after stocking. You can start selling from this time. But for high rate you have to wait until they reach 300-500 grams.

To produce monosex tilapia, farmers use hormone treatment. The hormone 17-alpha methyltestosterone (MT) is added to the feed of tilapia fry to induce male characteristics.

Disease Resistance

Monosex tilapia farming has been found to be more disease-resistant than traditional polyculture methods because the absence of female fish reduces the risk of parasites and diseases.

Feed Conversion Ratio

Feed conversion ratio (FCR) is the amount of feed consumed per unit of weight gain. Monosex tilapia have a lower FCR compared to traditional polyculture methods, making it a more efficient method of farming.
