Swimming In The Murk

Tilapia are the second most cultured fish worldwide after carp because they are easily cultured in a wide variety of environments and are generally hardy and disease-free.

However, they are susceptible to stress-induced diseases.

Extensive losses from disease outbreaks in aquaculture worldwide are a major threat to the sustainability of the aquaculture industry.

Intensive fish production often results in an increased incidence of diseases in fish, mainly due to poor water quality.

Unfortunately, water quality is one of the most overlooked aspects of pond management until it starts affecting fish production.

Most fish kills, disease outbreaks, and issues like poor growth, poor feed conversion efficiency, and similar management problems can be directly attributed to poor water quality.

The water quality of fish ponds is adversely affected by the accumulation of fish excreta, uneaten fish feed, and other organic compounds that may eventually lead to excessive growth of unwanted algae.

This not only impairs the pond water colour but also reduces the levels of dissolved oxygen in the water.

Such undesirable environmental conditions for the fish increase their susceptibility to infectious diseases and drastically reduce fish growth.

This was the situation our client, a fish farmer breeding red tilapia fish in Vietnam, faced.

The fish in his farm looked unhealthy, and he suspected they were infected.

Medication didn’t help as the fish continued to be lethargic with reduced appetites, leading to lower growth and survival rates.

Finally, he turned to us for a solution.

We had a ready recommendation: a combination of Bioclean Aqua Fish and Biogut Aqua.

Bioclean Aqua Fish is a consortium of beneficial bacteria that helps maintain water quality and colour, and stabilizes the dissolved oxygen concentration in water.

These bacteria help to reduce the levels of ammonia biologically and the production of toxic gases like H2S, ensuring a healthy pond and improved survival of fish.

The beneficial microbes in Biogut Aqua help fish better assimilate nutrients and microelements and improve their gut microflora.

This contributes to the development of a stronger immune system and an increase in the survival rates and growth performance of fish.

It also ensures maximum weight gain in the fish.

We recommended a dosage of 1 kg/hectare of Bioclean Aqua Fish and 5g of Biogut Aqua per kg of feed.

Soon, the results were evident.

After using Bioclean Aqua Fish in the fish pond, clear results were noticed within 85 days.

The biological reduction of ammonia in the water ensured there was no foul odour in the pond.

The colour of the pond water also showed significant improvement.

Stabilization of the dissolved oxygen in the pond by Bioclean Aqua Fish, complemented by increased feed intake and digestibility by the fish after using Biogut Aqua, improved the overall health of the fish.

Biogut Aqua helps enhance growth, stimulate the immune system, and improve the resistance of fish to infectious diseases.

There was an increase in the survival rate of the fish by 26%, and the fish looked healthy and active.

There was a significant improvement in growth performance, too.

And just like that, we took care of the fish, and the fish farm took care of itself!
