Feeding fish by response avoids wastage, maintains hygiene

Feeds are an important component of fish farming as they constitute of over 70 percent of the total operational costs. As a result, the key to any commercial fish farmer is to use the most cost-effective feed while taming waste.

Sourcing for the right feeds, record keeping of the trend in feeding, and maintaining hygiene around and inside the pond are some of the best practices that farmers are advised to observe by experts to reap big from the trade.

Farmers are also advised to embrace the best fish-feeding methods. According to Susan Nakimu from Ugachick, Uganda’s biggest fish feed producer, the best fish feed method is Feed by Response where fishes are fed only when they are hungry.

To feed by response, fish need to be trained to come and eat from the same place at the same time at the water’s surface. To achieve this, a farmer should initiate it by calling the fish at a designated fixed time and place. He can call on the fish for instance by making a sound or stump the ground before feeding. The farmer then pours in the pond at the specific point a handful of feed first. If the fish come, add more, if they do not come do not any feed.

The next day, the farmer is advised to do the same until the fish eventually learn that if they do not come to feed on time, there will be nothing left for them. It’s important to note that this may take several days for the fish to adapt.

In the first week, one should not give more than half the estimated required ration according to what is given to you by the extension worker or expert. This will help train the fish to feed intensively and rapidly. To keep the rapid feeding pattern, one should a container to broadcast the feeds in the pond rather than trickling them in.
