Uncle Pei said fishing, taking you to understand tilapia, and the methods of farming tilapia
Hello everyone, welcome to Uncle Pei said fishing. Listening to Uncle Pei said so many periods of knowledge about fish farming, I believe that everyone also has a basic understanding of fish farming, in fact, fish farming is not as complicated as imagined, the main thing to pay attention to is the water quality of fry and ponds, to prevent fish from being infected, and what Uncle Pei has to do is to prompt everyone to some small details, as well as to help everyone understand the habits of various fish, so that everyone can be more comfortable with fish farming, so what kind of fish are we going to introduce today? The one introduced to you today is a "foreign population", he is a tilapia.
Tilapia, also known as non-crucian carp, is a crucian carp native to Mozambique, now in many countries around the world are farmed, because tilapia adaptable, fast growth, so is currently the world's key breeding object of freshwater fish, and even known as one of the main sources of animal protein in the future, tilapia is a wide variety of species, basically edible, the appearance looks similar to crucian carp, but the body of tilapia is wider.
Tilapia is an omnivorous fish, generally based on various types of weeds and plankton in the water for a living, very gluttonous, the daily intake of food is very large, so the growth of tilapia is also very rapid, especially in the juvenile period, growing very fast. Although tilapia is a freshwater fish, but for the water containing salt also has a certain adaptability, in the seawater and fresh water can survive, can withstand low oxygen environment, but tilapia for temperature requirements are more exquisite, not resistant to high temperature nor low temperature growth The best suitable temperature is 16 ~ 38 ° C.
The meat of tilapia is delicious, the meat is tender, whether it is braised or cooked, the taste is good, and many parts of China today have the habit of eating tilapia, and many restaurants have added this dish to the menu, and many people are very confused when they see this name for the first time. In addition to the delicious meat, the nutritional composition of tilapia is also very rich, containing a variety of unsaturated fatty acids and protein components, but also contains calcium, sodium, phosphorus, iron and other trace elements, which can supplement the daily nutrients needed by the human body. So how can such a fish full of treasure be artificially farmed? Let Uncle Pei tell you.
First, pond conditions
First of all, in the selection of ponds, to choose a pond that is sheltered from the wind and the sun, the water source is sufficient, the water quality is clear, the water depth is best at 1.5 to 2 meters, and the pond should be disinfected before putting in the fry, and after disinfecting the bottom of the pond with quicklime, it will be placed for about seven days to add about 1 meter of water, and then add 20-30 cm thick silt to the soup base to facilitate tilapia activities.
2. Fry selection
When choosing fry for tilapia, be sure to choose a viable fry, pay attention to the appearance of the fry, and see if the scales are worn. Probably every spring when the water temperature warms up, the fry are put into the pond, and they can be polycultured with silver carp, bighead carp and other fish, but not with carp and crucian carp.
3. Feeding the bait
Generally, fry can be fed in water for 2-3 days, tilapia as an omnivorous fish, the diet is very wide, so if you want tilapia to grow rapidly, the prepared feed should contain a lot of protein. Generally, the feed made of wheat and corn is better, and it is fed twice a day at 8-9 o'clock in the morning and 3-4 o'clock in the afternoon.
Fourth, daily management
Inspect the fish pond in the morning and evening, pay attention to changes in water quality, you can use PH test strips to test the acidity and alkali degree of the pond, and properly disinfect the water body with quicklime to prevent tilapia lesions.
Follow Uncle Pei, take you around the fish pond, a variety of fish knowledge, let you benefit endlessly.
