According to the distribution area and water temperature conditions, the 17 species of fish can be divided into four types: warm-temperature species, cold-temperature species, warm-water species and wide-temperature species. The common ecological characteristics of silverfish populations are:

(1) Wide salt content:

(2) Wide temperature adaptability, most species are suitable for low temperatures;

(3) They live in the middle and upper layers of water and feed mainly on zooplankton;

(4) Strong reproductive adaptability;

(5) The life cycle is short, the population structure is simple, and the population size changes rapidly.

3. What impact does whitebait farming have on other fish?

If silverfish are mixed with other fish, it is very likely that the fish will float to the surface. Floating will also occur when the water temperature is above 20 degrees, which indicates that the dissolved oxygen content in the water is very low.

If you do not take immediate measures after discovering this situation, it will easily cause losses to silverfish and even large-scale deaths.

5. How to dry fresh whitebait into dried whitebait?

Preparation method

1. Raw material processing: Fresh silverfish will produce a lot of mucus after being taken out of the water, which needs to be cleaned. The cleaning method is particular. Pick out the miscellaneous fish, shrimps and other impurities, pour the silverfish into a wooden barrel filled with half a bucket of clean water in advance, add a few drops of cooking oil, stir by hand for 2 to 3 minutes, remove the foam and mucus, and filter and wash with clean water. Another method is to rinse the cleaned fresh silverfish with clean water, pour it into a light alum water and soak it for 1 to 2 minutes, then take it out. Pay attention to the use of alum. When the weather is good, the sun is strong, there is a small wind, and the evaporation is fast, the alum should be light or no alum (the ratio of alum to water is about 1:60, and the concentration is 1.5 degrees Baume); when the weather is cloudy and the water evaporates slowly, it is better to use a heavier alum (the ratio of alum to water is 4:60, and the concentration is 7 degrees Baume); on rainy days, the air is humid, and the concentration of alum water can be higher.

2. Drying: The first step is for fishermen to spread the processed raw materials on the fish drying nets (called pry cloth by fishermen, woven with hemp thread, dyed with pig blood and cassia bark, about five meters long, one meter wide, and 10 centimeters high on all four sides) on the boat, or pour them directly on the nets, flatten them, press them lightly, and dry them in the sun. After half a day under strong sunlight, when the whitebait is 60% to 70% dry, lift it on the pry cloth, which will become a rice crust. Remove it by hand and continue to dry it in the sun until it is 80% to 90% dry, and store it in the cabin temporarily. The second step is to dry it in the sun again after the aquatic company purchases it, until it is completely dry. Special attention should be paid to the sun drying, and it should not be dried or too dry, otherwise it will become broken pieces after packaging and become waste. If it has been over-dried, it can be covered with something that has not been completely dried, and gradually turned over and mixed until it is suitable for drying. The whole process must be paid attention to at all times, and it is important to grasp the right time.

3. Packaging: After the whitebait is completely dried, it is moved into the warehouse and piled on the flat ground covered with wooden boards. After a day and a night, the heat is dissipated and it is completely cooled before packaging. The packaging tool is a sack, each bag contains 100 kg. The packaging must be pressed tightly to avoid large gaps that absorb moisture and deteriorate, so the packaging is also very particular.

6. Natural enemies of silverfish?

No natural enemies.

After the Taihu whitebait was introduced to other lakes, the lack of natural enemies and its strong adaptability led to biological invasion. In many lakes where the Taihu whitebait was introduced, the production of native fish decreased or even became extinct.
