Application of Palm Kernel Meal as Supplementary Feed to Increase Fish Production in Fishery Businesses
Palm kernel meal (BIS) is a by-product of the palm oil industry and is obtained after the oil extraction process from the palm kernel. Usually, BIS is used as animal feed, especially for ruminants such as cattle. However, in recent years, BIS has also begun to be considered as an additional feed for fish, and the results are quite promising.
Why is palm kernel meal a good supplementary feed for fish?
1. Good Nutritional Content
Palm kernel meal contains nutrients that are good enough for fish growth. The protein and fat content in BIS can be a good source of energy for fish. In addition, BIS also contains crude fiber, detergent neutral fiber, and lignin which can help improve the health of the fish's digestive tract.
2. Abundant Availability
The palm oil industry is one of the major industries in Indonesia. Therefore, the availability of palm kernel cake is very abundant. This makes BIS an economical and easily accessible feed alternative for fish farmers.
3. Potential to Increase Protein Availability in Feed
Currently, fish feed commonly used by fish farmers still relies on rice and corn bran feed ingredients. The protein content in rice bran and corn is relatively low when compared to palm kernel meal. By using BIS as an additional feed, it can increase the availability of protein in the feed and ultimately optimize fish growth.
4. Environmental Benefits
In recent years, the palm oil industry has often been associated with environmental issues. One way to reduce the negative impact is to utilize palm kernel cake as supplementary feed. By using BIS, we can reduce the amount of waste and utilize it as a useful feed source.
How to feed palm kernel meal to fish
1. Drying and Storage
Before being used as feed, palm kernel meal needs to be processed first. The BIS should be well dried to reduce moisture levels and prevent mold growth. After drying, the BIS can be stored in an airtight container to maintain its quality.
2. Provisioning and Mixing
Before feeding palm kernel meal to fish, ensure that the BIS does not contain harmful ingredients or contaminants. If possible, the BIS used should have been laboratory tested to ensure its safety. In addition, BIS is also recommended to be mixed with other fish feeds to achieve an optimal nutritional balance.
3. Proper Usage
In feeding palm kernel meal to fish, it is important to pay attention to the right dosage. The optimal dose of BIS still needs to be further researched for each species of fish being farmed. If abnormal symptoms occur in fish after feeding with BIS, stop feeding immediately and consult a fisheries expert.
Benefits of Palm Kernel Meal Application in Fishery Businesses
1. Increase Fish Growth and Production
With proper application of palm kernel meal, fish can get balanced and better nutrition. This can help to significantly increase fish growth and production. On a fisheries scale, this increased production can have a positive impact on greater profits for fish farmers.
2. Reduced Dependence on Commercial Feed
Commercial feeds generally have a high price. By feeding palm kernel meal, which can be obtained at a cheaper price, fish farmers can reduce their dependence on expensive commercial feeds. This will help improve the welfare of fish farmers and reduce production costs.
3. Positive Impact on the Palm Oil Industry
Utilization of palm kernel meal as a feed additive can also have a positive impact on the palm oil industry. With the increasing demand for BIS, the palm oil industry can find solutions to manage and utilize this by-product. This positive impact also plays a role in maintaining the sustainability of the palm oil industry in the future.
4. Sustainability and Environmental Sustainability
Feeding palm kernel meal to fish can also contribute to environmental sustainability. By utilizing the side waste of the palm oil industry, we can reduce the amount of waste generated and optimize the use of natural resources. This means that the application of BIS feeding in fisheries also contributes to the sustainability of aquatic ecosystems.
Conclusion
The provision of palm kernel meal as a supplementary feed in fisheries has great potential in increasing fish growth and production. BIS has good nutritional content, abundant availability, and has the potential to reduce dependence on commercial feed. In addition, the use of BIS also has benefits for the environment and the palm oil industry as a whole. In its application, it is important to pay attention to processing, dosage, and monitoring of fish reactions to the feed given.
