Question 1: Can the dead yellow croaker be eaten? As long as it doesn't go bad, it can be eaten, but the taste is much worse. It's best not to exceed six hours, because after that, the fish will start to rot.

If you feel bad smell or die for too long, and it's not frozen, throw it away.

Question 2: Can the small croaker eat 20 points after it dies? It depends on how it dies. If it is anoxic, people can eat it normally. As the saying goes, dead fish and smelly shrimp do not harm people.

Question 3: My family loves to eat Ga fish, and if they can't finish it, they will always die. I want to ask how to raise Ga fish in my own house. Buy a fish tank at 40 cents, spread mud under it, then plant aquatic plants, press an Ehan filter bucket, press an Odyssey lamp and put nitrifying bacteria on it.

Question 4: How to raise the gawkish in the restaurant? I don't like to keep it separately. I feed the small fish and shrimp to keep the water dissolved. I have been raising it for almost two years, but I generally don't get sick, but I should pay attention to the fact that the outer skin of the fish should not be damaged. Don't add too much water and it is easy to get out and get injured. refer to

Efficient breeding of Astragalus membranaceus with bait

Huang Wei, also known as Huang Lading and Gayu, is a small freshwater economic fish. It is omnivorous, has strong adaptability, does not require high water quality, and is easy to introduce and domesticate. Because of its high nutritional value, it is increasingly favored by consumers, and it is also an excellent variety suitable for eating and fishing to improve the structure of cultured varieties. In recent years, we have continuously carried out the main culture experiments in small ponds, and all of them have achieved good results. Now, the key link bait technology for efficient culture of Astragalus membranaceus in small ponds is introduced as follows:

1, bait preparation

The food in natural waters is mainly shrimp, fish and fish eggs and some aquatic insects. Aquatic plants, etc., so fresh animal bait can be used for artificial breeding. In recent years, we have adopted self-made compound bait for domestication and feeding. The bait is made of imported fish meal, meat and bone meal, blood meal, soybean meal, rapeseed meal, dried fish worms and other feed additives, with an early protein content of more than 34% and a fat content of 4%. In the later stage, some imported fish meal can be replaced by small miscellaneous fish meal, with protein content of 30% and fat of 6%. Feeding bait must be fresh and free from mildew and rancidity.

2. Domestication

Wild Astragalus membranaceus likes to eat in the daytime and at night. After 5-7 days domestication under artificial breeding conditions, it can completely feed on the bait table during the day. After two days in the pond, the seedlings were domesticated by artificial feeding, with fixed feeding signals during domestication, and fixed-point and regular feeding training was carried out. After patient domestication for 5-7 days, the feed can be fed normally; The domesticated fry released in this way can be fed normally the next day after entering the pond, and the feeding method can adopt two forms: manual feeding and mechanical feeding.

3. Feeding amount

The whole feeding process should be divided into three stages. In the first stage, feed 4 times a day in May and June, and the daily feeding rate is 3%-5%; In the second stage, feed 3 times a day in July, August and September, and the feeding rate is 2%-3%; After the third stage 10, the bait was fed twice a day, and the feeding rate was 2%. On this basis, the feeding amount should be adjusted according to the weather and water quality. In the first and third stages, it is suggested to adopt the satiety method, that is, the fish on the bait should stop eating after 90% leaves the table; In the second stage, because the weather is hot and the water quality is easy to fluctuate, it is recommended to feed "90% full", that is, stop feeding after 80% of the fish on the bait leave Taiwan.

In addition, due to the large mouth crack of Pelteobagrus fulvidraco, the particle size of the bait should be increased accordingly, and the particle size of the adult fish feed can reach more than 5 mm with the particle size of 2.0 mm as the opening feed. It is required that the particles should have the stability of 15 minutes in water when using sinking hard particle bait; Using floating bait will better improve the utilization rate of bait.

Intensive culture technology of Pelteobagrus fulvidraco in pond

Pseudobagrus fulvidraco is a catfish order. Family, Pelteobagrus. Some places are also called Huang Lading, Huang Yagu, Yellow-fin Fish, Silurus japonicus and so on. Its body color is gorgeous, its meat is tender and delicious, its nutrition is rich, its edible rate is high, its vitality is strong, and its temperature range is wide, so it is a new breed that can be developed. The biological characteristics and intensive culture techniques in ponds are introduced as follows:

I. Biological characteristics

1.Morphological characteristics: long body length, wide and flat head, bulging back, flat abdomen, slightly flat rear part of body, thick and short tail handle, big mouth fissure, shorter jaw than upper jaw, fine teeth on upper jaw, 4 pairs of whiskers, small lateral eyes, hard spines on dorsal fin and pectoral fin, serrations on upper jaw, slightly fan-shaped pectoral fin ...... >; >

Question 6: How to eat yellow croaker ~ What's its nutritional value ~ What's the adverse reaction? You can stew it, or make soup. If you make soup, its nutritional value will be better. The meat of croaker is very fresh, so it's a good choice to cook it.

Question 7: Can Pelteobagrus fulvidraco be pickled? My domestic Pelteobagrus fulvidraco died a lot' but I can't eat it at once', so I want to ask if it can be pickled and dried. Generally speaking, it can be eaten in life! Because everyone doesn't like to waste' and the price of Chenghu hairy crabs is relatively high! Frozen in the refrigerator, it belongs to frozen products ~ just like the chilled things sold in the market! Scientifically speaking,' it is inedible' ~ because the nature, bacteria and nutrition of eaten animals and fruits have changed! So some people won't eat it!

I hope I can help you ~

Question 8: Why does the flower chain of Ga fish and loach kept in my fish tank always die? How many fish have you raised? Die one after another, mostly because of water quality problems! Don't be too dense, control the water quality!

Question 9: How to deal with the yellow diced fish? Kill the fish first, clean up the internal organs, do not scrape the scales, rinse the fish with water at 70-80 degrees Celsius, which will not only wash away the mucus, but also remove the fishy smell, and then marinate it with cooking wine and salt.
