What is the best fish to polyculture with loaches, and can loaches and goldfish be polycultured in f

a) Fish selection.

Loach ponds can also be polycultured, but the key issue is to pay attention to the fact that the feeding habits of polyculture fish are not the same as those of loaches. For example, in general, rural areas prefer to raise carp and crucian carp, but these two kinds of fish cannot be mixed with loaches, because they are both bottom fish like loaches, and they are omnivorous, and both sides will not grow well together.

It is best to choose grass, bream, silver carp and bighead carp for fish polycultured with loaches. These four species of fish are pelagic fish, grass and bream eat grass, while silver carp and bighead carp eat plankton, and their feeding habits are not much contradictory to loaches. The grass and bream can also be used as bait for loaches to eat the remaining plant fragments, which can save breeding costs and improve economic benefits.

2) Matching ratio.

The proportion of loach and fish polyculture should be scientific, and the proportion of grass, bream, silver carp and bighead carp should not be too large, generally only accounting for 20% of the total stocking. In addition, due to the shallow water level of the adult loach pond, these fish cannot be released as adult fish, and can only be stocked with fish.

3) Feeding management.

Fish feed during the day, but loaches feed at night, so when feeding, fish should be fed first, and then loaches should be fed to avoid fish and loaches competing for food.

Loach ponds should strengthen daily management, insist on patrolling the pond, especially in summer and autumn, pay attention to the floating head of fish in the pond. New water should be added regularly to ensure that the water quality is fresh and lively, and the survival rate of pond fish is improved.

Loaches and grass goldfish cannot be polycultured in tanks.

The requirements of the living environment are different, so it is not suitable for raising together at all. Loach is a loach fish, docile temperament, the main food is rotting fish and aquatic weeds and algae and small water insects to feed, loach likes to inhabit the bottom of still water, often haunts lakes, ponds, ditches and paddy fields at the bottom of the silt surface rich in plant debris, prey on plankton, smaller aquatic insects. Its living environment is mainly shallow silt.

The muddy silt environment is best for it to survive. Goldfish, on the other hand, prefer a clean and clean environment, and muddy water will be lazy and easy to breed parasites. In addition, loaches secrete a sticky substance, which is easy to breed bacteria, which is also the reason why loaches can spoil water.

Grass goldfish are the ancestors of all goldfish. Relevant historical records have appeared in the Warring States Period, and its most important birthplace is in the south of the Yangtze River, mainly in Hangzhou and Jiaxing in China. Grass goldfish is commonly known as red crucian carp or golden crucian carp, the body is spindle-shaped, the tail fin is not forked, and the dorsal, ventral, thorax and anal fin are normal.

Strong physique, strong adaptability, wide range of food, tolerant breeding. In addition to red, there are also red and white flowers, five flowers, etc. It is suitable for large-scale breeding in parks and natural waters, and can also be raised in courtyard tanks and aquariums.

Physical factors such as temperature, light, humidity, precipitation, wind, rain (snow) all affect the life of goldfish to varying degrees, and the main thing that has a direct impact on the life of goldfish is temperature. The optimal water temperature is 20 28, and the higher the water temperature, the more vigorous the metabolism of the goldfish, and the faster the growth and development of the goldfish. Lives in water and survives on dissolved oxygen in the water.

Generally, goldfish require more than milligrams of dissolved oxygen, and the lowest is between milligrams, below this limit, goldfish will all die. Carbon dioxide levels of more than 60 milligrams of carbon dioxide in the water body can jeopardize the normal growth and development of goldfish. Goldfish can survive within this range of water pH, but the pH value is in the optimal range.

Grass goldfish are fed nutritious animal feed and white sesame seeds. Animal feed such as daphnia, earthworms, mealworms, green worms, skin worms, etc. The main feeds are earthworms and white sesame seeds.

Both red and black earthworms can be fed.

Loaches are not suitable for polyculture in fish tanks and are easy to mix with water.

Crucian carp and loach are best polycultured with crucian carp, because loaches and crucian carp have a particularly strong growth ability, and they will not eat each other, so they are most suitable for polyculture together.

Rearing snails in loach breeding ponds not only does not require any other feed, but also can obtain a double harvest. It is because snails can enrich various plankton and aquatic plants in the water, such as rotifers, cladocera, silk earthworms, etc., and can also produce young snails. And these are the natural feed of loaches, and the feces of loaches are good feed for snails, which truly achieves the mutually beneficial symbiosis of loaches and snails.

It is best to choose grass carp, bream, silver carp and bighead carp for fish polycultured with loaches. These four species of fish are pelagic fish, grass carp and bream eat grass, while silver carp and bighead carp eat plankton, and their feeding habits are not much contradictory to loaches.

1. Loach is rich in active substances, and tofu contains calcium, protein and other nutrients. Loach with black fungus has the effect of nourishing qi and nourishing blood and enhancing physical fitness, and is very suitable for women with weak qi and blood and the elderly who are weak and weak as a tonic.

2. It can be eaten by ordinary people, but people with spleen and stomach deficiency and cold, diarrhea, cold and fever should not eat more, and patients with eczema, skin mold rentitis and other diseases should not eat it.
