The Environmental Linkage of Mangrove Vegetation to the Production of Milkfish (Chanos Chanos) in Silvofishery Ponds in Lubuk Kertang Village, West Brandan District, Langkat Regency
Introduction
Mangrove vegetation plays a vital role in coastal ecosystems, particularly in increasing fish production. The study aims to understand how the density of mangrove forests affects the production of milkfish (Chanos Chanos) in Tambak Silvofishery Lubuk Kertang Village, West Brandan District, Langkat Regency. This article will discuss the environmental linkages of mangrove vegetation to the production of milkfish in Silvofishery ponds.
The Importance of Mangrove Vegetation in Coastal Ecosystems
Mangrove vegetation is a crucial component of coastal ecosystems, providing a habitat for various species of fish, including milkfish. The existence of mangroves offers shelter and protection for fish seeds from predators, creating an environment rich in nutrients. Mangroves also contribute to reducing erosion and maintaining water quality, which is essential for fish growth. The mangrove vegetation in the study area consists of several types of plants, including Rhizophora Apiculata, Rhizophora Mucronata, and Avicennia Marina.
The Effect of Mangrove Density on Milkfish Production
The study found that the density of mangrove forests in Silvofishery ponds has a significant impact on milkfish production. Ponds dominated by mangrove types have a higher density of mangroves, resulting in a higher average weight of fish (147.4 grams/head) and a lower total harvest (39.1 kg). In contrast, ponds dominated by seedling type mangroves have a lower density of mangroves, resulting in a lower average weight of fish (95 grams/head) and a higher total harvest (41.4 kg).
Analysis of the Link between Mangrove Vegetation and Fish Production
The link between mangrove vegetation and milkfish production can be seen from how mangroves function as an ideal habitat for fish. Mangroves provide shelter and protection for fish seeds from predators, creating an environment rich in nutrients. Mangroves also contribute to reducing erosion and maintaining water quality, which is essential for fish growth. The existence of mangroves in Silvofishery ponds not only affects the number of fish that can be maintained but also on the health of the fish itself.
Factors Influencing Milkfish Production in Silvofishery Ponds
Other factors that influence the production of milkfish in Silvofishery ponds include water temperature, water quality, and the amount of feed given. The optimal water temperature for the growth of milkfish ranges from 28-32 ° C, so that the temperature conditions in the two ponds are classified as ideal. In addition, the presence of healthy mangroves and appropriate density can increase the amount of natural feed, such as zooplankton and phytoplankton, which are a source of nutrition for fish.
Conclusion
This study shows that mangrove vegetation has a significant impact on milkfish production in Silvofishery ponds. The right mangrove density not only increases the number of fish that can be maintained but also contributes to the health and growth of the fish. Therefore, the management of mangrove forests and silvofishery ponds is very important to maintain the balance of ecosystems and increase fisheries production in coastal areas. This sustainability is not only beneficial for fish farmers but also for ecosystems as a whole.
Recommendations
Based on the findings of this study, the following recommendations are made:
- Maintain the density of mangrove forests: The density of mangrove forests in Silvofishery ponds should be maintained to ensure the health and growth of milkfish.
- Monitor water temperature and quality: Water temperature and quality should be monitored regularly to ensure that they are within the optimal range for milkfish growth.
- Provide adequate feed: Adequate feed should be provided to milkfish to ensure that they grow and thrive.
- Manage mangrove forests sustainably: Mangrove forests should be managed sustainably to maintain the balance of ecosystems and increase fisheries production in coastal areas.
Future Research Directions
Future research should focus on the following areas:
- Investigating the impact of mangrove density on other species of fish: The impact of mangrove density on other species of fish should be investigated to determine the extent to which mangroves affect fish production.
- Examining the effects of water temperature and quality on milkfish growth: The effects of water temperature and quality on milkfish growth should be examined to determine the optimal conditions for milkfish production.
- Developing sustainable management practices for mangrove forests: Sustainable management practices for mangrove forests should be developed to maintain the balance of ecosystems and increase fisheries production in coastal areas.
