Fish Manure: Fish bone, Fish Waste and Now Fish Poop?”
Aquaculture has been driving the goals of solid waste treatment systems with fish manure. Higher fish consumption results in an equal volume of discarded fish material in the form of low-value by-product or waste. This waste is being utilized as fish manure across various industries on the backdrop of its advantages over chemical-based fertilizers. Different types of fish manure products such as fish hydrolysates, fish soluble nutrients, fish emulsion and fish silage are extensively used in various activities of crop production.
Aquaponics Uses Fish Poop as Fish Manure
Liquid form of fish manure has surfaced in the market and is gaining momentum as a sustainable solution. Manufacturers of this liquid form of fish manure are popularizing their products as organic, that uses no chemical additives and contains only fish products. Another interesting development comes from the area of aquaponics where fish poop is being used as fish manure. The process basically uses fish waste along with bacteria to grow plants. Large facilities are being setup to practice aquaponics and use fish waste as fish manure. Researchers believe that aquaponics has the potential to create solutions for the problems that may arise before the farmers in the coming years. Aquaponics utilizes fish poop as fish manure in combination with greenhouse technology to produce crops all the year round. It is getting increasingly adopted as the technology that aids in building a healthy source of income for local businesses where the business owner is in control of every day food requirements. It benefits the manufacturers in terms of less water consumption as the aquaponics systems are generally re-circulating types where water is re-utilized.
Fish Bones-based Manure in Demand
Dried fish sludge is used by manufacturers to produce fish manure provides a solution more efficient than mineral fertilizers. On-land hatcheries are continuously expanding their fish sludge collecting capacity in order to compose them into fish manure. Manufacturers are conducting research and development to develop treatment technologies for fish manure. Treatment technologies like mechanical filtering are employed to increase fish manure efficiency by surging the dry matter content of fish manure.
Fish bones are getting converted into fish manure on the pretext of making the soil phosphorous rich. Generally, fertilizers are extracted from phosphate rocks which negatively impacts the phosphate content of the soil. Fishermen in regions like Senegal are converting fish by-products such as bones and shell into fish manure that can be used for agricultural purposes. Local communities are rapidly adopting this approach of producing fish manure to improve their economic status. Many communities are collecting the vast amounts of fish manure dumped in sea by big fishing companies and converting it into fish manure.
Is Integrated Farming the future?
Integrated farming is gaining popularity owing to its positive attributes like enhanced production and increased income. Pig and fish integrated farming is practiced in some regions across the globe. The practice has gained attention as a form which is socially, economically and ecologically viable. Fish manure obtained from this practice, though not pure, is highly nutrient rich. This type of fish manure is fed into the fish pond to produce high-protein plankton which caters to the nutritive requirement of certain species of fish. The fish manure in combination with pig manure forms a rich source of different digestive enzymes.
Organic fertilization techniques are increasingly employed to produce fish manure. Organic fish manure is known to improve the soil health with greater penetration of water and other nutrients. Fish manure is highly demanded for its potential to replenish the soil with the depleted nutrients in unproductive soil regions. Liquid form of fish manure is attracting consumers with its ease of application and effectiveness.
