Discoloration of Loach in Lianyungang

Hello, teachers! I would like to ask about the discoloration of Loach material! The salesman of the company reflects that the discoloration of Loach with our feed is slow. I would like to ask, what factors will the discoloration of Loach be related to? Thank you! -- temperature, light, and water quality-- the discoloration of other manufacturers is relatively fast. What's going on? Ask the landlord: do you want to change from normal body color to abnormal body color? Or in the opposite direction? If the normal color caters for a while without positively guiding consumer awareness, the initial Loach culture will not go far; if it is now an abnormal body color, it can start from the aquaculture water quality, water depth, light, density, sediment type and thickness, feed should start from the adjustment of large material ratio, and then consider the proportion of various natural pigment sources brought by feed raw materials. It is not advisable to add synthetic pigments or any chemical agents to the water. Don't follow the old ways of Pelteobagrus fulvidraco and turbot fish-- quote from cwq23452 published in 2009-8-11 09:31, ask the landlord: do you want to change from normal body color to abnormal body color? Or in the opposite direction? If the normal color caters for a moment without directly guiding consumer awareness, the initial Loach culture will not go far; if it is now an abnormal body color, it can be seen from the aquaculture water quality, water depth, light, density, sediment type and thickness, feed should first be from the big I do not know very well, mainly listen to the salesman under the reflection. It reflects that the discoloration of other manufacturers is relatively fast, about half a month, but our material needs a month. But the final growth effect is OK.

Corn by-products, such as DDGS and corn germ meal, can be used. I looked at it yesterday and found that the farmers over there had such requirements for the color of the Loach. Their fry are mainly collected from Loach in Henan Province. Generally, after domestication and breeding for a period of time, some loaches will slowly fade from cyan to pink, the color becomes lighter, and the color is lighter than that of wild Loach in the sun. The farmers there have formed such an idea: if whose Loach first changes from bluish gray to pink, it means that the Loach grows fast and whose feed is good! Now I have such doubts as to whether this is a normal discoloration, whether there is such a stage in the growth process of the Loach in Henan, and whether the time of discoloration is normal. What should we pay attention to in the formula?! It's a pity that there are no photos and forgot to bring the camera, hehe! -- I hope you will send out more problems in actual production, discuss them together and improve them together. -- do you have any friends from Henan to answer it? This is mainly because Korean customers prefer this discolored Loach! Loach in the rapid growth period, if all aspects are normal, its discoloration will be normal. Mainly focus on the selection and quality of large raw materials! -- quoted from ligye123 published in 2009-8-19 10:32 this is mainly because Korean customers like this discolored Loach! Loach in the rapid growth period, if all aspects are normal, its discoloration will be normal. Mainly focus on the selection and quality of large raw materials! Thanks to this friend for his information. I feel like you're doing this, too. Yes, mainly Korean customers who prefer this kind of Loach with different colors. And the price of this kind of Loach is also higher than that of the general color Loach. You said you have a choice on the big materials. Can you give me some advice? And are there any additives such as colorants? Thank you!
