Measures for cultivating goldfish broodstock after wintering

1. Adjust the water quality of the broodstock. During the wintering period of goldfish, the original pool water (abbreviated as “old water”) is basically cultured, and the water is generally not completely changed. Even if the pool water is too thick, some method of removing some of the pool water and injecting some new water is adopted. After the beginning of spring, the method of replacing most of the old water and injecting new water into the original pool should be adopted. But do not need to change the water every day, depending on the changes in water quality. After the convulsion, the temperature of the water rises accordingly as the temperature rises. At this point, you should thoroughly change the water. Change the water every other week.

2, timely feeding fresh live bait. The bait is mainly fed with red worms, but the amount should not be too much, generally to ensure that it can be eaten within 2 hours. If you feed too much, it will not only affect the water quality, but also make the broodstock overweight and affect the spawning.

3. Use as little medication as possible. Spring is the period of the goldfish's ovulation, and it is also the development period of the eggs in the broodstock. If the amount and frequency of medications are too much, it will affect the spawning of broodstock and even affect the quality and quality of the fry. The best way is to maintain a good water quality environment, feeding high-quality live bait to control the occurrence of fish diseases, so as to ensure the normal development of broodstock.

4, protect the wall of the moss. Moss can function to purify water and photosynthesis to increase dissolved oxygen. It is important that you want a goldfish with a good ecological environment. Therefore, when changing the water, you must not brush the bottom of the pool and the moss that grows on the pool wall. You should leave a part of the moss. If the bottom of the pool is brushed too clean, with the sun's rays, there will be reflections at the bottom of the pool. The goldfish will float on the surface of the water all day without affecting the normal growth. If there are residual baits, it is easy to make the water quality worse, resulting in the death of the goldfish.

PGA is a water soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation. PGA is a sticky material first found in "natto", a fermented soybean. PGA is an unusual anionic, naturally occurring homo polyamide that is made of D & L glutamic acid units connected by amide linkages between alpha amino & gamma carboxylic acid groups.
Gamma-poly-glutamic acid (gamma-PGA) is a natural occurring, multi-functional, and biodegradable biopolymer.

It is produced through fermentation by Bacillus subtilis using glutamic acid. PGA is consists of glutamic acid monomers crosslinked between α-amino and γ-carboxyl groups, and the molecular weight of PGA is usually between 100~1000 kDa. It is water-soluble, edible and non-toxictowards human, and is environment friendly. It has broad applications in the fields of medicine, food, cosmetics, and water treatment.
