The Effect of Giving RGH Hormone Dosage on Different Feed Protein Levels on Growth and Survival of Koi Fish (Cyprinus carpio)

Introduction

Koi fish (Cyprinus carpio) is a type of fish that is highly valued for its economic worth and is known for its ease of maintenance. One strategy to increase the rate of growth and shorten the time of cultivation is to use growth hormone. Growth hormones that are naturally produced by the pituitary gland in the fish's body are limited in number. To overcome this limitation, the use of recombinant growth hormone (RGH) is a potential choice. This study aims to determine the effect of giving RGH hormones with different feed protein content and to determine the best dosage and protein levels for the growth of koi fish.

Methodology

In this study, a random design group (RAK) was applied with two treatments and three replications. The treatment consists of the addition of RGH hormones with a dose of 9 mg/kg of feed (H3), 6 mg/kg of feed (H2), and 3 mg/kg of feed (H1), as well as three content of feed protein namely 35% (PA), 30% (Pb), and 25% (PC). The study lasted for 60 days with the aim of evaluating the increase in weight, growth, survival, feed conversion, and water quality that functions as a supporting factor.

Results

The results showed that the addition of RGH hormones had a significant impact on the growth of koi fish. The treatment that gives the best results in increasing the weight and length of the fish occurs in a combination of feed with a protein content of 30% and the dose of the hormone RGH 9 mg/kg of feed, namely in PBH3 treatment, with an average result of an increase in weight of 4.83 grams and length 2.75 cm.

Discussion

Provision of RGH with the right level of feed protein not only increases physical growth, but can also affect the survival of fish. The use of this hormone allows fish to utilize nutrients from feed more effectively, thereby increasing the efficiency of feed conversion. In addition, water quality also needs to be considered because it can affect the health and growth of fish. By managing good water quality, koi fish can grow optimally.

Conclusion

Overall, this study shows that the use of RGH in combination with appropriate feed protein content can increase the growth and survival of koi fish. This research makes an important contribution to the development of koi fish farming and is expected to be a reference for farmers to significantly increase crop yields.

Implications for Koi Fish Farming

The findings of this study have significant implications for koi fish farming. The use of RGH in combination with appropriate feed protein content can increase the growth and survival of koi fish, leading to increased crop yields and improved profitability for farmers. Additionally, the study highlights the importance of managing water quality to ensure optimal growth and health of koi fish.

Future Research Directions

Future research directions include investigating the optimal dosage and duration of RGH administration, as well as the effects of RGH on other physiological parameters such as stress response and immune function. Additionally, studies on the use of RGH in combination with other growth promoters or feed additives may provide further insights into the mechanisms underlying the growth-promoting effects of RGH.

Limitations of the Study

This study has several limitations. Firstly, the study was conducted in a controlled laboratory setting, and the results may not be directly applicable to commercial koi fish farming operations. Secondly, the study only investigated the effects of RGH on growth and survival, and did not examine other physiological parameters such as stress response and immune function. Finally, the study only used a limited number of treatment groups, and further research is needed to fully elucidate the effects of RGH on koi fish growth and survival.

Recommendations for Future Research

Based on the findings of this study, we recommend the following for future research:

Investigate the optimal dosage and duration of RGH administration.
Examine the effects of RGH on other physiological parameters such as stress response and immune function.
Investigate the use of RGH in combination with other growth promoters or feed additives.
Conduct studies on the effects of RGH on commercial koi fish farming operations.

Conclusion

In conclusion, this study demonstrates the potential of RGH to increase the growth and survival of koi fish. The findings of this study have significant implications for koi fish farming and highlight the importance of managing water quality to ensure optimal growth and health of koi fish. Future research directions include investigating the optimal dosage and duration of RGH administration, as well as the effects of RGH on other physiological parameters such as stress response and immune function.
Frequently Asked Questions (FAQs) about the Effect of Giving RGH Hormone Dosage on Different Feed Protein Levels on Growth and Survival of Koi Fish (Cyprinus carpio)

Q: What is RGH hormone and how does it affect koi fish growth?

A: RGH (Recombinant Growth Hormone) is a synthetic hormone that mimics the natural growth hormone produced by the pituitary gland in fish. It stimulates the growth and development of koi fish by increasing the production of proteins and other essential nutrients.

Q: What are the benefits of using RGH hormone in koi fish farming?

A: The use of RGH hormone in koi fish farming can increase the growth rate, improve feed conversion efficiency, and enhance the survival rate of koi fish. It can also help to reduce the time required for koi fish to reach market size.

Q: What are the different feed protein levels used in this study?

A: The study used three different feed protein levels: 35% (PA), 30% (Pb), and 25% (PC). The results showed that the combination of feed with a protein content of 30% and the dose of the hormone RGH 9 mg/kg of feed (PBH3) gave the best results in increasing the weight and length of the fish.

Q: How does the water quality affect the growth and survival of koi fish?

A: Water quality plays a crucial role in the growth and survival of koi fish. Poor water quality can lead to stress, disease, and reduced growth rates. Good water quality, on the other hand, can promote optimal growth and health of koi fish.

Q: Can RGH hormone be used in combination with other growth promoters or feed additives?

A: Yes, RGH hormone can be used in combination with other growth promoters or feed additives to enhance the growth and survival of koi fish. However, further research is needed to fully elucidate the effects of combining RGH with other growth promoters or feed additives.

Q: What are the limitations of this study?

A: This study has several limitations, including the use of a limited number of treatment groups, the lack of examination of other physiological parameters such as stress response and immune function, and the study's controlled laboratory setting.

Q: What are the recommendations for future research?

A: Based on the findings of this study, we recommend the following for future research:

Investigate the optimal dosage and duration of RGH administration.
Examine the effects of RGH on other physiological parameters such as stress response and immune function.
Investigate the use of RGH in combination with other growth promoters or feed additives.
Conduct studies on the effects of RGH on commercial koi fish farming operations.

Q: What are the implications of this study for koi fish farming?

A: The findings of this study have significant implications for koi fish farming. The use of RGH hormone in combination with appropriate feed protein content can increase the growth and survival of koi fish, leading to increased crop yields and improved profitability for farmers.

Q: Can RGH hormone be used in other types of fish?

A: While this study focused on koi fish, RGH hormone can potentially be used in other types of fish. However, further research is needed to determine the efficacy and safety of RGH hormone in other fish species.
