In a partnership with DNOCS – NATIONAL DEPARTMENTS OF WORKS AGAINST DROUGHT, in Ceará, Millenniun tested efficiency of Enzilimp’s use into tanks of tilapia mating, a place of large and continuous presence of organic material generated by animals excrements and daily provided feed.
This large amount of organic matter (sludge) deposited into the bottom of the vivarium generated serious hindrances to the operators upon collection of the larvae as well as allergic reaction to them. The water was too much dim, with low levels of dissolved oxygen, generating high mortality and reduced production rate. Interruptions of production for draining of the vivarium and water change were also common.
Millenniun’s technical team, assisted by Enzilimp’s Distributor in Ceará State, oriented and qualified DNOCS’s technicians towards product application, with full cooperation of the agency and concerned people.
After the second week of application, an improvement of the dissolved oxygen level in the water was observed, continuing to escalate until the fourth week, when the parameter was stabilized.
During the third week, a relevant clearing of the tank water was observed, confirming significant enhancement of the environment. The fact could be proven when, after the fourth week, a strong decrease of the organic matter in the bottom of the vivarium was observed as well as reduction of the allergic reaction (itches) in the operators.
After the fifth week of treatment, post-larvae production experienced a significant increase, continuing to escalate until it was stabilized at 100,000 pls., a fact that had not been observed anymore due to the adverse conditions of the vivarium.
According to the statement and Expert Report of the Chief Agronomic Engineer of the Researches Center, Dr. Pedro Eymar Campos Mesquita, tank production was decreasing up to 10,000 pls. by the end of two months operations.
Besides those facts highlighted by DNOCS, after 18 consecutive weeks using Enzilimp, the following benefits were accomplished:
•Lower water consumption, avoiding the need to drain it, high financial/environmental cost involved and polluting impact in the adjacent water body;
•Significant reduction of algae production, as well as the algae adhered to the hapas (nets of the cages);
•Reduction of labor for larvae collection, cleaning of the cages and vivarium, as well as its draining;
