What is the most important eliminet in Biofloc system ?
Is it water ? is it fish? or is it feed ? farmers could
have differences over them but there is one think every one agrees on, yes ,
even buyers and that is GROWTH ! how much biomass you get in your crop cycle.

Growth is the king in Biofloc system
but not many farmers focus on it, especially the new one
|
Biofloc system or any other form of fisheries is the
game of getting higher FCR (The Feed Conversion Ratio) In layman's term how much biomass you can get in
the least feed spending.
[ "The feed conversion ratio is an indicator that is commonly used in all types of farming, as well as in the field of research. It can provide a good indication of how efficient a feed or a feeding strategy can be. In the context of aquaculture, the F.C.R. is calculated as follows: F.C.R. = Feed given / Animal weight gain."

Growth is the biggest challenge now, long gone the days when amino used to be the focus point in biofloc system .
* Don’t underestimate the power of amino, it can still give hard time to beginners.

[ Remember Amino is the biggest enemy in Biofloc system
Ammonia is the main waste product excreted by the nitrogen metabolism of fish. This metabolic phenomenon is specific to fish; it allows them to draw a maximum amount of energy from feed protein degradation. However the usefulness of this specific metabolism is limited by the high toxicity of ammonia. When present at high concentrations in water ammonia can impair fish performance. This constitutes a major risk for high-density fish farms.

What contributes to the growth of fish, in other word what make fish gain weight ? well its feed weather Biofloc or external one. that's not rocket science that's common sense, Well common sense is not very common. Remember in layman's terms, fish only eats when they are happy and they are not happy when they are too cold, too hot not enough oxygen to breath or highly concentrated water (with amino)
well the answer lies in the mood of fish , if they are happy they eat more and gain weight if they are not they won't, well then what makes fish unhappy ? here is the list of most common reasons.
1- high level of amino
2-Low DO . if fish can't breath they won't eat
3-Temperature. If the temperature of water is not the happiest level of fish they won't be feeling like eating anything
In case of any of these condition , fishes might no die, thay will not gain weight
Conclusion
- Focus on growth,
- Maintain biofloc tank water at fish happiest level.
- Don't overlook temperature. Find out what temperature your fish like and maintain it to gain faster weight
- Maintain proper feeding interval
- Remember longer crop cycle time due to slow mass gain will effect FCR ie your profit.
- Remember longer crop cycle time due to slow mass gain will effect FCR ie your profit.
Cost of production depends heavily on the duration of your crop, you are continuously running pumps and your other over heads like labour charges etc add to the cost
You might have less mortality but you don’t have growth enough
Well question remains the same, What is the most important eliminet in Biofloc system ? Is it water ? is it fish? or is it feed ?
