Introduction

The golden fish, also known as the mascoki fish (Carassius auratus), is a popular species in the aquarium trade and is widely used in research studies. Spawning of this species is a complex process that requires careful management and handling of the fish parents, as well as the provision of suitable substrates for the eggs and larvae. Despite the importance of spawning in the reproduction of golden fish, the success rate of hatcheries is still relatively low. This study aims to investigate the effect of different substrates on the spawning of golden fish and to identify the most suitable substrate for this purpose.

Background

Spawning of golden fish is a natural process that occurs in the wild, but it can also be induced in captivity through the use of various techniques and substrates. The success of spawning is influenced by several factors, including the handling and management of the fish parents, the provision of suitable substrates, and the maintenance of optimal water quality. In this study, we used a Completely Randomized Design (CRD) to investigate the effect of three different substrates on the spawning of golden fish.

Materials and Methods

Experimental Design

This study used a Completely Randomized Design (CRD) with three treatments: water hyacinth (Eichhornia crassipes), raffia ropes, and coconut fiber. Each treatment was repeated three times, resulting in a total of nine experimental units. The parameters measured in this study were the number of eggs produced, hatching rates, and survival rates of the golden fish larvae.

Substrates

The three substrates used in this study were:

Water Hyacinth (Eichhornia crassipes): This is a popular aquatic plant that is widely used in aquariums and ponds. It is known for its ability to absorb excess nutrients and to provide a safe place for eggs and larvae to develop.
Raffia Ropes: This is a type of natural fiber that is commonly used in aquariums and ponds. It is known for its ability to provide a safe place for eggs and larvae to develop, as well as to absorb excess nutrients.
Coconut Fiber: This is a type of natural fiber that is commonly used in aquariums and ponds. It is known for its ability to hold water and to provide a safe place for eggs and larvae to develop.

Results

The results of this study showed a significant difference in the number of eggs produced in each substrate. The highest hatching rate was obtained in the coconut fiber substrate, with a percentage of 63.70%. The water hyacinth substrate produced a hatching rate of 61.20%, while the raffia rope produced a hatching rate of 45.79%. The water quality measured during the study had an average pH of 7 and a temperature of 28 °C, which is an ideal condition for spawning of golden fish.

Discussion

This study shows that the selection of appropriate substrates can have a major effect on the success of spawning golden fish. The coconut fiber substrate provides the highest hatching rate, which may be caused by its ability to hold water and provide a safe place for eggs. On the other hand, the water hyacinth substrate and raffia rope even though it also produces eggs, but with a success rate that is less than coconut fiber.

Improving the quality of the spawning environment not only by choosing the right substrate, but also by maintaining water quality. Parameters such as pH and water temperature must be considered to create optimal conditions. Further research can be done to explore the use of other substrates that may be better and test other factors that affect the spawning of golden fish.

Conclusion

The conclusion of this study is the importance of selecting substrates in increasing the success of spawning golden fish. By utilizing the appropriate substrate, fish farmers can increase crop yields and the success of the fish reproduction, which will certainly benefit the fishing industry and fish farming.

Recommendations

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

Use of Coconut Fiber: The coconut fiber substrate provides the highest hatching rate and should be used as the preferred substrate for spawning golden fish.
Maintenance of Water Quality: The water quality must be maintained at optimal levels, with a pH of 7 and a temperature of 28 °C, to create an ideal condition for spawning of golden fish.
Further Research: Further research can be done to explore the use of other substrates that may be better and to test other factors that affect the spawning of golden fish.

Limitations

This study has several limitations that should be considered when interpreting the results. These include:

Small Sample Size: The sample size of this study is relatively small, which may limit the generalizability of the results.
Limited Substrates: The study only used three substrates, which may not be representative of all possible substrates that can be used for spawning golden fish.
Limited Parameters: The study only measured three parameters, which may not be sufficient to fully understand the effect of substrates on the spawning of golden fish.

Future Directions

This study provides a foundation for further research on the effect of substrates on the spawning of golden fish. Future studies can build on this research by:

Testing Other Substrates: Other substrates can be tested to determine their effect on the spawning of golden fish.
Measuring Other Parameters: Other parameters can be measured to gain a better understanding of the effect of substrates on the spawning of golden fish.
Exploring Other Factors: Other factors that affect the spawning of golden fish can be explored to gain a better understanding of the complex process of spawning.
