In fish farming, many farmers have reported unsatisfactory yields and poor economic returns from their pond-raised fish. The main issue often lies in improper feeding practices—both the quantity and timing of feed are not properly managed. To effectively determine when and how much to feed, farmers should observe several key signs:
First, monitor the fish's feeding behavior. If the feed is consumed in less than 2 hours, it may indicate that the amount is insufficient. On the other hand, if the fish remain near the feeding area after eating and don't disperse, they might still be hungry. Conversely, if there’s leftover food on the feeding tray, it suggests that the amount can be slightly reduced.
Second, during routine pond inspections, pay attention to water conditions and fish activity. If the surface is unusually calm and the fish are active, yet no parasites are visible on their bodies, this could signal hunger. For example, fry or fingerlings swimming in tight groups around the pond edges often show signs of severe hunger.
Third, regularly check the growth of the fish, ideally once a month. If the fish aren’t growing as expected or show significant size variation, it may mean they’re not being fed adequately.
Fourth, in ponds with mainly eel-like species, if the fish have large heads, thin tails, and weak swimming ability, this could be a sign of chronic underfeeding.
Lastly, in carp ponds, if the water appears consistently muddy and yellow (not due to storms or floods), it may indicate that the carp are starving.
By observing these indicators, farmers can better adjust their feeding strategies, leading to healthier fish and improved profitability.
