"Through this practice, a ton of animal protein can be obtained in less space than that needed with cattle", the expert from the United Nations Food and Agriculture Organization (FAO) told agence Prensa Latina.
"We need more protein and fish also brings us more fatty acids, essential for the growth of children. It also allows older people to improve their circulatory system", he added.
Pulgarín is in Cuba for the beginning of the FAO TCP/CUB/3501 project "Establishment and Implementation of a Genetic Improvement Program for Freshwater Fish", which started this week in Havana with a two-week workshop for specialists, researchers and officials related to this sector.

I agree that aquaculture is an efficient system to produce large quantities of animal protein for human consumption. But the quality and type of the feed is an important factor. As long as fish meal and fish oils are used, it might be efficient, but definitely not sustainable. The focus should not be "efficient" but "sustainable and efficient" aquaculture. I see no reason why these cannot be combined.
The FAO is reporting about these issues for several years and states that the use of insects is one of the most sustainable solutions to produce (animal) proteins for animal feed.
And I completely agree with that...
Solve waste problems, produce insects without the use of land, water, fertilizers & pesticides and use the insects as an alternative for fish meal. It´s sustainable, possible and proven. And from a nutrient perspective, it is a very efficient system when organic residues are being used and converted into proteins, oils and fertilizers.
Therefore I would like to conclude with: insect production is the most efficient system to obtain animal protein.

Of course, the quality of animal protein fish depends on the fish food. But not only. You must know the mechanisms of fish growth. Postnatal growth of fish accompanied by processes of hypertrophy and hyperplasia. Feed should be specifics for each stage of growth.
Hypertrophy-one feed. Hyperplasia - other food.

Agree with the topic. That is true, because of my experience two decade ago. But now the problem is to get high quality feed in order to take advantage of the improved tilapia potencial for growing fast. For example, with good quality feed plus algae, in 3 to 6 months, you can produce fish of 450 grams at all, with good management. I got this experiencie, in a big farm of 49 hectare.

In Central Kenya one of the key challenges facing the growth of aquaculture is access to quality feeds. A kilo of imported tilapia grower feeds goes for USD1.8 making it difficult for farmers to venture into this fast growing food industry.

Other questions are to do with how and where the protein component of aquaculture feed to pelagic and other carnivorous species is produced.
I am aware that some can come from algae, but some literature suggests that palatability can be a problem with algae.

Hi, I am starting in Aquaculture in Tilapia Geomembrane Tanqs..
cap, 25,000 lits each.....want to develop 30 tanqs....any experience you would like to share in regard of ratio of development with consumtion feeds..??

Hi, with the bad rap tilapia aquaculture is getting in the media , especially in Asia, leaves alot to be desired where the viability of small farmers is impacted. Here in St. Kitts we have perfected the science of growing tilapia in full strength Atlantic seawater. In addition the fish is grown in Geomembrane lined tanks. This is practised in an intermitent one-way flow through system. The question of obtaining animal protein may only be in the quality of fish feed. Are there other factors?

Algae can be used for fish feed using good quality water in closed-loop photobiorectors or tanks. Cattle have been fed an algae mix to thousands of cattle in the US with good results. Samples with COA's are available. For information: barry@nationalalgaeassociation.com
