46 Fish Farming Questions and Answers:

1 :: Do you know where was the fish raised and how was it caught?

wild Alaskan salmon. Line-caught is best, but probably not necessary once you're in Alaska. Line-caught somewhere else greatly increases the fish's chances of being wild outside the fish farm.

2 :: Suppose we are planning to start hatching very soon. We tested the ph of our water yesterday and its acidic (ph 4). What can we do to make it suitable for hatching?

Get sodium carbonate and add it to your tank, it also depends on the size of your tank, like for 1500 litres u can add three spoonful then test. you can also add soda ash to the water. If you have a reservoir, add soda ash to it once it is filled with water, leave for few hours then pump it to d pond it will boost its pH.

3 :: Explain how do you fertilize?

organically, composted cow manure, sustainably, fish oil, anything that sounds like it started with the earth or an animal. It's great if a farmer says, "Well, we're not certified organic," because they will likely follow that up with the fact that they grow organically but can't afford or don't choose the certification. That nets you a safe, chemical-free product without the extra cost.

4 :: Do you know what are the returns from Fish Farming?

Returns depend on inputs. Inputs are correct fish stocking rates, good quality identifiable seed, proper fertilization, vigilance and strong management. Harvest techniques, proper magement of harvesters, transportation to market and having reliable staff to sell the produce is also very important. On average, you should expect to sell over Rs. 100,000 worth of fish per acre (gross). Average net income from fish farms is over Rs. 50,000 per acre per year but with proper management, net profits of Rs. 100,000 per acre per year can be achieved.

5 :: Tell me how much will the 1000 small fishes cost?

Catfish have sizes: we have fingerlings, juveniles and post juveniles. I always advise potential farmers to go for juveniles since most of them don't have facilities to handle fingerlings. Healthy juveniles cost between 25-30 naira

6 :: Tell me what's this pipe i often see popping out of the pond meant for?

Any pipe in a pond is for the control of water flow in and out of d pond.

7 :: Tell me where do the animals live?

outside regularly, on pasture

8 :: Which is the best type of culture for Pakistan?

The best type at present (2010) for the province of Sindh is a land based modified extensive or at best semi-intensive finfish / fish culture.

9 :: Do you know why is Alaska a good place to grow oysters?

Oysters can grow very well in cold water if there is abundant, high-quality plankton. Many estuaries in Alaska produce so much high-quality plankton during certain times of the year that Alaskan shellfish can match growth achieved by shellfish raised in warmer waters of the Pacific Northwest. Cold, clean water also reduces bacterial contamination, extending shelf life and assuring safety when eating cultured oysters, especially when eaten raw.

10 :: Do you know how much will it cost to feed 1000 fishes till they are ready for sale?

I could see you really know what you want and this your question will make those that deceive others shiver. I have heard where they will tell you, 'each fish will consume 200naira worth of feed for 6 months and you will attain above 1kg'. Oh my God!!! How is this feasible? Definitely it is not and yes i said it is NOT feasible because different factors and condition determine the response of fish to feed at any particular time. Factors like water quality (turbidity, ph, and temperature. e.t.c), stress and health. What I advise is to set aside considerable amount for feed. For 1000 pcs of fishes and your target is 1kg and above fed for 6 months, I will advice you keep 250,000 for feeding.
