Feeding Fish

[Patrick Thirkell]

'Towards Sustainable Aquaculture in Europe'.
There are ethical issues with catching wild fish to feed farmed fish, is this ruining the whole reason for farming? Maybe we should do the reverse...

I visited Iceland recently, they have a project farming Caplin, releasing them in a fjord where they are quickly predated on by Cod. The Cod remain near this resource, and are selected by hand net when marketable! Neat and clever idea, and it works.

I hope to grow Mussels to feed Tilapia, one reason is the problem of getting fish food this far north (Moray Firth), the other is the cost. Could this be a winner-please respond!

What are the principle dietry requirements for Talapia in the wild? I ask this as it is the first question I always ask myself when considering sustsainable aquaculture systems

Hi Vinod,

I am in Elgin, between Aberdeen and Inverness on the Moray Firth. I am about to put in mussel rope droppers off the coast in Spey Bay.

One of the problems with mussel farming is what to do with the waste, misshapen mussels and such, this bio waste costs a fortune to dump, but it is good protein, and I feel the Nile Tilapia, a more carnivorous species, might enjoy this food.

I am raising Tilapia as a food fish in 1 000 litre tanks, passing the water out into polytunnels for hydroponic strawberry production, a biofilter that will return the water to a heat exchanger and biomass heater and back to the tanks.

I feel the fish would like to forage for their food on the bottom of the tank, and am trying to make their environment as interesting and natural as possible, even to the extent of inefficiency. I do believe the quality of the produce will be superior, and it is all about quality.

So, what do you think? Have you any Tilapia tips for me, I am quite impressionable!

Merci Pierre
It is wise to mimic the natural environment, this is what the fish has been evolving in for milennia. I think tilapia is a hardy, mostly omnivorous group that is successful because it is so quick to adapt to new surroundings, so much so that it might become a seafish before too long, they already tolerate brackish water well.

Actually am in love with fishery business and i have an access to more than 1000hectares swamp area of land to develop for fishery in nigeria, the one close to the ocean and one far a bit, i need the investor who can come to nigeria for verification and do the business together, if their is any investor am ready to invite he/she.
I believe you are the right person to contact, just contact me through my phone number or my e-mail add < hollarng@yahoo.com >for the business transaction.

Thanks.

Patrick,
I am also interested in finding a secondary crop to raise as fodder for my tilapia. We are currently raising crayfish in our Bio-filter pond in a maintenance capacity as they tend to be great housekeepers, but they do nothing to aid in the maturing of the tilapia. Here in Arizona we are experiencing a surge of the invasive 'quagga' mussel which is very small and multiplies like crazy. If in fact tilapia will consume freshwater mussels I could see a possible diet of duckweed and mussels that could be easily produced in the same facility, thus completing the cycle. If you advance with your experiment, I would be interested in hearing updates.
