Shrimp growth rate is considered the primary factor in affecting pond profitability in typical shrimp farming under normal production conditions. Despite its importance, few shrimp producers actually know the maximum growth rate potential of their shrimp.
Growth rate is a very important characteristic in farmed species, and faster growth rate contributes in many ways to the profit equation. When shrimp grow faster, they are cultured in ponds for a shorter period of time, which significantly reduces the risk factor, and there are opportunities to grow the shrimp to a larger size or to increase the number of pond rotations crops per year.
A reduced time spent in the pond can result in higher survival and lower feed conversion ratios, and total operating costs are reduced, contributing to better results and higher profits that can be quite significant. To manage shrimp growth rate effectively, it is first important to understand how shrimp grow, and a hypothetical example is presented in Fig.
There are three phases that can be identified in the growth curve of shrimp. First, from approximately postlarvae 1, or PL 1 to 3 to 4 grams, the animals grow exponentially, where the incremental increase in weight increases at an increasing rate. During the second phase, from approximately 3 to 4 grams to approximately 25 grams, the growth rate of shrimp is lineal, where the incremental increase in weight is constant per unit of time.
And during the third phase, at about 25 grams or when the animals start reaching sexual maturity, the females continue to grow at the same lineal rate, but the growth rate of the males declines.
We selected the latter to focus on because most of the increase in animal weight takes place during the lineal phase and quality data is more easily collected.

I was simply curious how long it takes for baby shrimp to become adults?
Click to expand They're of sellable size at about 2 months. So if you just bought them it'll be at most 4 months of waiting before they're sexually mature. Nitrates and are best controlled by doing regular water changes. Pheromones are hormones which act externally, hormones are contained within the body and affect the body from within. Pheromones can affect the body when within the local environment instead of within the body itself. Water changes are the simplest way to control the extent of those pheromones.
Diet An incorrect diet will starve the shrimp of essential nutrients it requires to make its body, a very good example of this is if you do not feed your shrimp or fish enough protein they will not produce eggs.
Replenishing biologically important trace and minor elements. Replenishing carbonates. Diluting pheromones. Diluting nitrates. Removing dissolved solids. All these things have a sway of shrimp growth so making water changes of the appropriate volume and make them often enough, this has a huge impact not only on the expansion of shrimp but on the well being of the shrimp too.
Jag Got Plants? Aug 18, 1, 1 0 41 Marysville, Wa. They grow extremely slow, so slow I think I'm going to try to breed something else.. Jag said:. Jan 2, 1, 0 0 Winchester, Kentucky. I got Cherries about 3 months ago. I got one that was really tiny. I feed them food that I made that has plenty of plant material, fish foods, calcium, etc. Mine are growing fairly quick. The one I received that was really tiny has grown about twice his size now.
It should be mature in another month or 2. The tetra's will eat the baby shrimp if they can get to them. The only safe fish for the shrimp would be Oto's and I've heard Hillstream loaches.
