Can compound fertilizer be used during crayfish farming?

Compound fertilizer can be used in appropriate amounts for crayfish farming, but it is recommended not to use it during the seedling stage; instead, specialized aquatic fertilizer can be chosen.

Can compound fertilizer be used for crayfish farming?

1. Compound fertilizer can be used for red swamp crayfish farming.

10-15 days before stocking the shrimp fry, generally apply 100-200 kg of fully decomposed manure such as pig manure per mu of water surface to cultivate plankton and provide an appropriate amount of organic debris as shrimp feed. Before filling the pond with water, install a water barrier net, preferably 60-80 mesh, to prevent predators in the water from entering. Keep the pond water depth at 50-80 cm and the transparency between 30-40 cm.

2. Disadvantages of compound fertilizer

Applying inorganic fertilizer very easily causes pond water quality indicators (ammonia nitrogen, nitrite, phosphate) to rise, affecting the farmed animals; inorganic fertilizer takes effect quickly but also dissipates quickly and is not long-lasting; the algae community produced by inorganic fertilizer is single and unstable, easily causing acute stress in farmed animals, and in severe cases even gas bubble disease.

In general, fertilizing water requires distinguishing between new and old ponds; after selecting the right water-fertilizing product, how to fertilize the water must take into account the pond structure and distinguish whether the pond is an old pond or a new pond.
