The Level of Use of Azolla Pinnata in Feed for the Growth of Tilapia (Oreochromis niloticus)

Tilapia (Oreochromis niloticus) is one of the most widely cultivated and consumed fish species globally, with a high economic value. However, the increasing demand for tilapia has not been accompanied by optimal cultivation practices, leading to suboptimal growth rates and feed efficiency. One potential solution to this problem is the use of Azolla Pinnata, a water plant that is rich in protein and can be easily cultivated. This study aims to investigate the level of use of Azolla Pinnata in feed for the growth of tilapia.

Tilapia is a popular fish species that is widely cultivated in many parts of the world. However, the increasing demand for tilapia has put pressure on the industry to produce more fish while maintaining optimal growth rates and feed efficiency. Commercial feed is the primary source of nutrition for tilapia, but it is often expensive and can have a negative impact on the environment. Azolla Pinnata, a water plant that is rich in protein, has been identified as a potential alternative to commercial feed.

This study used a 6 cm tilapia that was kept in a 50 cm diameter container as many as 12 units. The method used was a random design complete with 4 treatments, namely:

  1. 100% commercial feed without the addition of Azolla flour.
  2. Commercial feed 94% with the addition of 10% Azolla flour.
  3. Commercial feed 88% with the addition of 20% Azolla flour.
  4. Commercial feed 82% with the addition of 30% Azolla flour.

The results showed that Azolla Pinnata flour can be used as a substitute for some fish meal in tilapia feed. The fourth treatment, namely 82% commercial feed with an additional 30% Azolla flour, provides the best growth with a weight gain of 4.33 grams and a length of 2.23 cm. Feed efficiency in this treatment reached 38.67%.

The results of this study showed that Azolla Pinnata flour can be used as a substitute for some fish meal in tilapia feed. The fourth treatment, namely 82% commercial feed with an additional 30% Azolla flour, provides the best growth with a weight gain of 4.33 grams and a length of 2.23 cm. Feed efficiency in this treatment reached 38.67%. These results suggest that Azolla Pinnata flour can be used as a sustainable and environmentally friendly alternative to commercial feed.

The use of Azolla Pinnata as tilapia feed has several advantages, including:

*** Vegetable protein sources that are easily obtained: Azolla Pinnata is a water plant that is easily cultivated and contains high protein (around 30-35%). *** Environmentally friendly: Azolla Pinnata can absorb nitrogen and phosphate from water, so that it can help reduce water pollution. *** Increasing feed efficiency: The use of Azolla Pinnata can reduce feed costs and increase feed efficiency.

However, further research needs to be done on the optimal dose of Azolla Pinnata in tilapia feed. This is to ensure that the use of Azolla Pinnata does not have a negative impact on fish health and water quality.

The use of Azolla Pinnata in tilapia feed is one of the efforts to increase tilapia production in a sustainable and environmentally friendly manner. This research is expected to open up new opportunities in the development of more economical and environmentally friendly tilapia feed. Further research is needed to determine the optimal dose of Azolla Pinnata in tilapia feed and to ensure that its use does not have a negative impact on fish health and water quality.

Based on the results of this study, the following recommendations are made:

  1. Further research is needed to determine the optimal dose of Azolla Pinnata in tilapia feed.
  2. The use of Azolla Pinnata as tilapia feed should be implemented on a larger scale to ensure its sustainability and environmental friendliness.
  3. The development of more economical and environmentally friendly tilapia feed should be a priority in the tilapia industry.

This study has several limitations, including:

  1. The sample size was small, and further research is needed to confirm the results.
  2. The study only investigated the use of Azolla Pinnata as tilapia feed and did not consider other factors that may affect tilapia growth and feed efficiency.
  3. The study did not investigate the long-term effects of using Azolla Pinnata as tilapia feed.

Future research should focus on the following areas:

  1. Determining the optimal dose of Azolla Pinnata in tilapia feed.
  2. Investigating the long-term effects of using Azolla Pinnata as tilapia feed.
  3. Developing more economical and environmentally friendly tilapia feed.

In conclusion, this study has shown that Azolla Pinnata flour can be used as a substitute for some fish meal in tilapia feed. The use of Azolla Pinnata as tilapia feed has several advantages, including being a vegetable protein source that is easily obtained, environmentally friendly, and increasing feed efficiency. However, further research is needed to determine the optimal dose of Azolla Pinnata in tilapia feed and to ensure that its use does not have a negative impact on fish health and water quality.
