A Detailed Guide to Northern Pike Farming Techniques: How to Raise the World's Longest-Lived Fish
The pike, also called the northern pike, is a common freshwater fish and the most ferocious carnivorous fish of all freshwater fish. Pike grow quickly, their flesh is tender and refreshing, the flavor is delicious, and the fishy smell is not strong, so its food value is very high. Below is an introduction to the farming techniques for the “world's longest-lived fish”, the northern pike!
I. Pond Preparation
Before farming pike, you must first prepare the farming pond. Control the pond area according to the farming quantity, generally around 6-7 mu, with depth controlled at more than 2 m, ensuring an abundant water source, good drainage and irrigation capacity, and the ability to adjust water temperature normally. Then carry out a comprehensive and thorough disinfection of the pond. About 3 days before releasing the fry, splash an appropriate amount of soybean milk into the pond to increase the biological feed in the pond. Then place plants such as water hyacinth on the pond to provide shade, and plant an appropriate amount of aquatic grass as hiding places for the pike, to prevent the pike from killing each other.
II. Feed Preparation
The pike is a carnivorous fish, so the main bait is mainly small fish. Therefore, before stocking pike fry, we must put sufficient bait fish into the pond. The body length of the bait fish should be kept at around 5 cm, and it is best to breed them in the original pike pond. However, before stocking, the bait fish must be disinfected to prevent them from carrying pathogens into the pond and affecting the growth of the pike. Then apply fertilizer appropriately to cultivate the bait fish. The bait fish are mainly carp, silver carp, and so on. When the bait fish have grown to about 5 cun, release pike fry of the same growth size.
III. Grow-Out Management
As the pike grows for longer and longer, its requirements for the palatability of the bait fish become stricter, and the amount eaten each time gradually increases. Therefore, we must reasonably adjust the feeding frequency and amount according to the growth progress of the pike, and pay attention to carrying out a sorting and separate rearing treatment once a month, keeping those of the same size together, to prevent the pike from killing each other and the undesirable phenomena of large eating small and strong eating weak. Then, under sufficient and healthy feed and normal management, when the pike is raised to the end of the year, its body weight can reach about 1 kg, reaching the market standard, and it can be harvested at the appropriate time.
IV. Disease Prevention and Control
The pike has strong growth ability and generally does not develop diseases, with a low incidence rate. However, under artificial farming conditions, the disease resistance of the pike is reduced. When farming, we must do a good job of management. If management is poor, the pike is highly prone to bacterial gill rot, which severely hinders the pike's breathing and leads to death from hypoxia in the later stage. During the farming process, we must keep the water quality good, clean, pollution-free, and cool, creating a good growth environment for the pike. After the disease occurs, promptly splash agents such as Yulüjing into the pond for disinfection and prevention, to avoid worsening the condition.
The above is a brief introduction by Tuliu.com to pike farming techniques. Pike are divided into spotted pike and northern pike. This method is mainly suitable for northern pike. Management during the farming process is very important, and everyone must pay close attention to it to avoid unnecessary losses.
