The raw materials of floating fish feed are wide and various, mainly including fish meal, wheat meal, yeast powder, mineral and vitamin premix, soybean meal, cottonseed meal, peanut meal and rapeseed meal, etc. However, without proper and scientific formulation, floating fish feed may show some defects like incomplete nutrition, high feed coefficient and low feed utilization rate. Therefore, it’s essential to choose a formula with good stability, low feed coefficient and high feed utilization rate, and master the production process above all.There are many fish feed production line https://www.zenopelletmachine.com/product/floating-fish-feed-production-line/ on the market ? how can we get high quality fish feed pellet on the market ?
Color: Fish feed is various, which makes it a little difficult to identify from colors. In general, main ingredients and raw materials of fish feed pellets produced by professional feed factory contain fish meal, soya bean meal, rapeseed meal, cottonseed meal and other protein materials, so the color of fish feed would be yellow-brown or brown, depending on the property of raw materials ...
... when produced. But please note that the color would be sightly different even for fish feed products with the same variety made by the same one factory because raw materials may come from different sources at different periods.
Smell: Fish feed always has the taste of rapeseed meal, fishy taste or a little garlic flavour (some factories may add anti-infective drugs – Allicin). However, some producers adopt some methods like adding flavouring agent to prove their feed with big fish meal content, selling seconds at best quality prices. After immersing inside the water, the fishy taste would disappear or fade.
Water resistance: Some fish farmers always hope that the water resistance of fish feed could be longer and longer because they think only long water resistance could reduce the waste of fish feed. But actually this opinion is one-sided. The common fish in aquaculture need frequent ingestion, so increasing feed times can also receive the goal of not wasting fish feed. Besides, the appropriate of water stability is around 3-6 minutes.
Specification: Standard feed production line https://www.zenopelletmachine.com/ would produce a series of fish feed with various sizes according to different fish growth stages. At the same specification, fish feed pellets are uniform with bright and shiny appearance, and the cuts of fracture surface are smooth. Moreover, the length of pellet is around 1.5-2.5 times of its diameter. If this proportion is of imbalance, it would heavily affect the palatability of fish food, leading to the waste of feed.
Crushing fineness: Fish, due to the poor digestion ability, needs the fish feed easy to digest and absorb. So for ingredients of fish feed, if crushing fineness is better, its utilization factor would be higher. High quality fish feed has the features of thinner grinding fineness and even ingredients.
Sandy soil content: In order to lower competitive price in market and go for profit, a few companies may add sandy soil during fish feed production process. Fish farmers can do random sampling and taste the samples. If fish feed tastes containing soil, then it proves that there is sandy soil in pellets. And the other way is to use water to prove whether sandy soil exists: place a small amount of sample in a transparent glass, soak the sample with water until it is completely dispersed, and stir it again and again, and let it stand for observation. If the upper layer appears turbid, the bottom of the cup has fine sand, indicating that sandy soil exists and the content of sandy soil is also visible.
