Berhasilnya #budidaya lobster di tahap pendederan menjadi Peta Jalan Budidaya #Lobster #Indonnesia

Summary

The Center for Marine Aquaculture in Lampung focuses on innovative lobster rearing techniques, specifically from pueruli to 5 grams. By experimenting with container design, sheltering strategies, and artificial feed, the center aims to improve survival rates, reduce cannibalism, and optimize growth. Emphasizing sustainability, the center is developing user-friendly technology for community adoption, aiming for mass lobster production with a high survival rate. Supported by Ministerial Decree number 17 of 2021, the center shares its breakthroughs and provides seed lobsters to cultivators, making lobster farming more accessible and profitable in Indonesia.

Takeaways

• 😀 The Center for Marine Aquaculture in Lampung focuses on lobster rearing from pueruli (larvae) to the fourth segment (150 grams and above).
• 😀 Lobster rearing is divided into two stages: land-based (for segment 1) and sea-based (in floating net cages).
• 😀 The first stage of rearing (0 to 2 months) sees slower growth, but after reaching a certain size, growth accelerates significantly.
• 😀 Artificial feed testing is underway, showing that lobsters are willing to consume it, but more trials are needed to finalize the formula.
• 😀 The rearing system is flexible, with containers varying in size, shape, and water depths (20 cm to 1 meter), showing that lobsters can thrive in different environments.
• 😀 Shelters play a vital role in reducing cannibalism, with cast cement and black nets providing effective hiding places for lobsters.
• 😀 The main challenges to high survival rates (SR) are cannibalism and molting failure, both of which can be mitigated with appropriate shelter and better feed formulations.
• 😀 Nutritional content of feed is crucial in reducing cannibalism, with ongoing experiments on fish, shrimp, and artificial feeds.
• 😀 Average survival rates during rearing vary: 30-40% from pueruli to 2 grams, and 70-80% from 2 to 3 months, with a goal of improving survival in future studies.
• 😀 The recommended lobster rearing density is no more than 100 lobsters per square meter, and containers should be cleaned regularly, with lobsters moved to fresh containers every month.
• 😀 Ministerial Decree number 17 of 2021 allows for the cultivation of lobsters from the very early stages, providing new opportunities for aquaculture in Indonesia, with a survival rate of up to 60-70% in controlled conditions.

Q & A

What is the main focus of the Center for Marine Aquaculture in Lampung?

The main focus of the Center for Marine Aquaculture in Lampung is conducting engineering activities in the field of lobster rearing, specifically from pueruli (young lobsters) to the fourth segment (150 grams and above). They work on both land-based and sea-based rearing systems.

What are the two primary stages of lobster rearing at the center?

The two primary stages of lobster rearing at the center are: 1) from pueruli to 5 grams (the first segment), which is carried out on land in specialized containers, and 2) from 5 grams to 30 grams, which may involve both land and sea-based systems.

Why is the first segment of lobster rearing considered the most critical?

The first segment, from pueruli to 5 grams, is considered the most critical because it is the most challenging stage of lobster cultivation. Proper care and management are essential for high survival rates, and it sets the foundation for successful growth in later stages.

What is the average survival rate (SR) for lobsters in the first two months of rearing?

The average survival rate for lobsters in the first two months of rearing ranges between 30-40%. This is considered relatively low but improves as the lobsters grow.

What are the main causes of mortality during the lobster rearing process?

The main causes of mortality during lobster rearing are cannibalism and molting failure. These issues are often exacerbated by insufficient shelter or inadequate feed.

What role do shelters play in reducing mortality rates in lobsters?

Shelters play a critical role in reducing mortality rates by providing security for lobsters, especially during molting. Proper shelters help minimize cannibalism, which often occurs when lobsters cannot find a safe hiding place.

What types of feed have been tested for lobster rearing?

Several types of feed have been tested for lobster rearing, including natural feeds like shellfish and fresh fish, as well as artificial feeds such as fish and shrimp feed. While natural feed is preferred for rapid growth, artificial feed is being explored as a viable alternative.

What is the recommended lobster density for rearing?

The recommended density for lobster rearing is no more than 100 lobsters per square meter. Maintaining this density helps ensure optimal growth conditions and reduces stress on the lobsters.

What measures are being taken to improve the artificial feed used for lobster rearing?

Efforts are underway to develop and perfect artificial feed formulations. This includes experimenting with various feed combinations to ensure they meet the nutritional needs of lobsters, aiming to reduce cannibalism and promote healthy growth.

How has the Marine Affairs and Fisheries Ministerial Decree number 17 of 2021 impacted lobster aquaculture in Indonesia?

The Marine Affairs and Fisheries Ministerial Decree number 17 of 2021 has provided a framework for the development of lobster aquaculture in Indonesia. It has created opportunities for communities to engage in lobster cultivation, from the earliest stages, and has supported the distribution of seed lobsters for cultivation purposes.
