Breeding Cachamas in small spaces

in Project HOPE8 months ago



The cachama is a fish from the Amazonian rivers and the Orinoco basin, whose meat is highly prized. Since the late 1960s it has been farmed in Brazil, Venezuela, Peru and Colombia, in ponds or artificial lagoons.

Given that its size can reach up to 1 meter and weigh more than 30 kilos in its natural state, the fact that it supports high planting densities and accepts concentrated food has caused many farmers to take part of their farmland for the construction of artificial ponds whose water is also used for irrigation of vegetables.

On a large scale it is a lucrative business and on a small scale it is used to cover food needs and to obtain money for subsistence, for this reason the breeding of these fish is possible to find them even in areas close to the cities.

The important thing is that the water circulates so that the oxygen is maintained at acceptable levels, for that reason the water inlets are placed at a certain height so that the fall of the liquid generates it.

Naturally there are three types of this fish identified by their color, the black, red and white, but it has become more popular to breed a hybrid species resulting from the crossing of the black and the red, which are of a dark golden color and have been given the names cachamay, cachamoto and tambacú.



Whoever plants in small spaces such as ponds or tanks, introduces the Alevines, so called the fish that has passed from its larval stage to the alevin stage, since from this moment it begins to form and develop its organs, which it has purchased, since this fish does not reproduce in captivity, in water, at a calculated rate of 4 per square meter.

These will be fed twice a day, in the morning and in the afternoon, and the food will be changed according to the growth stages of the fish that goes from fry to the stage of growth and fattening that makes its weight reach 500 grams in 6 to 8 months. This is an average weight for those who breed in small spaces but it multiplies when it is in larger extensions.

Many farmers supplement the fish feed with products of their own harvest, such as lechoza or papaya, guava, avocado, banana and grated yucca, among others.

According to the time of the fish, the protein content of the concentrated feed is reduced so that the first 20 days should contain approximately 45%, from 21 to 63, 38%, from 64 to 98, 32% and from 98 onwards only 24%, this is the fattening stage.

The fish are marketed directly or sold to markets, fresh from the ponds. The fish loses approximately 8% of its weight when it is serrated and weighs 500 grams or more, but up to 13% if it weighs no more than 300 grams.



It has gained a space as an alternative for family feeding and given the fish's ability to adapt, many even breed them in very small spaces such as plastic or concrete tanks where only a few dozen of them can fit.

Another characteristic of the cachama is that it can withstand altitudes up to a certain limit, which is why in the Andean Cordillera there are cultivations of them, as well as the fact that it can be bred with other species of fish.

Every day more and more people are venturing into the breeding of this fish in small spaces in Venezuela.

Thanks for the interesting post, learned a lot of new information. I've never heard of this kind of fish before, I think it's very tasty. I try to eat more fish in my diet than meat, as it is much healthier for the body.

Thank you for reading me. This fish is very healthy

Regards dear friend @joseph1956.

I really appreciate your new publication within the Project Hope community. But I must point out that the topics that characterize our community include:

  • technology,
  • blockchain,
  • artificial intelligence,
  • machine learning,
  • cybersecurity,
  • gaming (on the blockchain)

as well as:

  • economy,
  • business,
  • marketing,
  • psychology, social media, etc.

In this case, your post does not seem to fit within our work philosophy. Maybe I'm wrong, I'll thank you if you could elaborate yourself about it.
Please try to address the issues we request in the future.

Greetings, I consider that the topic discussed fits perfectly both in economics, since it is an alternative way to obtain benefits as in business, for the same reason, on the other hand, fish farming is linked to agriculture and the concept of this is well remarked "Set of economic activities".
I guess the etcetera after psychology and social media indicates that scientific topics are allowed.
I will be more specific in the future about the topics covered. Thank you

Dear, @joseph1956.

I consider that the topic discussed fits perfectly both in economics, since it is an alternative way to obtain benefits as in business, for the same reason, on the other hand, fish farming is linked to agriculture and the concept of this is well remarked "Set of economic activities".

I agree, but reading your post, I couldn´t find any phrase that made reference to monetary gains, marketing, supply, and demand of the cachama.

This is the single line related to commerce:

The fish are marketed directly or sold to markets, fresh from the ponds.

You could have emphasized the economic part but you didn't.

It is a matter of optics, in the post I indicate the way it is bred and the result of this derives in profits or savings. I emphasize that the fish is a hybrid, something that is part of technology, but the general idea is to show new alternatives of economic income that are being practiced in the country.

I totally agree.
Have a nice day appreciated friend @joseph1956.

thank you for visiting my blog, in the next ones I will deal with the topics more punctually according to what you recommend me.

I'm sure you will.

Hi @joseph1956
I didn't know about this particular way of fish breeding, I sincerely believe that it is a great alternative, because its characteristics allow it.
It is good to know a little bit about everything. This besides allowing to have a good source of protein at home, can allow to have an extra economic income.
But it's good that you are shortening @juanmolina's recommendation regarding themes and giving a more targeted approach to Project Hope's subject matter.

can allow to have an extra economic income.

Greetings, thanks for reading me, in the same answer you have reinforced the optics that I have of it

A very important agri-food alternative, my friend, is the breeding of cachamas, greetings and thanks for sharing. Regards
