Freshwater Shrimp (Decapoda) in Aceh: A Promising Resource for Aquaculture Development

Introduction

Freshwater shrimp (decapoda) in aceh: a promising resource for aquaculture development. Explore the aquaculture potential of 13 Macrobrachium freshwater shrimp species in Aceh, Indonesia. M. lanchesteri shows promise for sustainable cultivation.

Abstract

Freshwater shrimp of the genus Macrobrachium represent an underutilized resource in Aceh Province, Indonesia, despite the region’s rich freshwater ecosystems and the global economic value of shrimp aquaculture. This study presents the first integrative assessment of the aquaculture potential of 13 Macrobrachium species collected from 27 freshwater sites across Aceh. Species were evaluated using morphological identification, ecological field surveys, literature reviews, and key biological parameters, including egg size, larval development, salinity tolerance, and local consumption. Most species exhibited r-strategist reproductive traits and prolonged larval stages, requiring brackish or marine environments, which limited their suitability for closed freshwater systems. However, M. lanchesteri displayed abbreviated larval development and completed its life cycle in freshwater, making it a strong candidate for sustainable aquaculture. M. idae was assessed as moderately suitable due to extensive supporting literature and local use. These findings highlight both the constraints and opportunities for freshwater shrimp cultivation in Aceh, providing a foundation for future research and development in aquaculture diversification and local food security.

Review

This study offers a valuable and timely assessment of the aquaculture potential of freshwater shrimp, specifically the genus *Macrobrachium*, in Aceh Province, Indonesia. Addressing the underutilization of these natural resources in a region rich in freshwater ecosystems, the authors undertook the first integrative evaluation of 13 *Macrobrachium* species. Their comprehensive approach combined morphological identification, ecological field surveys, literature reviews, and an analysis of key biological parameters, thus laying a robust foundation for understanding the feasibility of cultivating these species. The research successfully identified a diverse array of *Macrobrachium* species from 27 sites, revealing important insights into their reproductive biology. A significant finding was that while most species exhibited r-strategist traits and prolonged larval stages requiring brackish or marine environments – thereby limiting their suitability for closed freshwater systems – *Macrobrachium lanchesteri* emerged as a strong candidate for sustainable aquaculture. This species uniquely demonstrated abbreviated larval development, completing its entire life cycle in freshwater. Additionally, *Macrobrachium idae* was identified as moderately suitable, supported by existing literature and its local consumption patterns, suggesting varied potential across the surveyed species. Overall, this study makes a significant contribution by meticulously delineating both the constraints and the promising opportunities for freshwater shrimp cultivation in Aceh. By pinpointing *M. lanchesteri* as a particularly viable species for sustainable aquaculture, the findings offer concrete directions for regional development in aquaculture diversification and enhancing local food security. This research serves as an essential baseline, providing critical data and a strategic framework for future investigations and practical implementation aimed at unlocking the economic and nutritional benefits of Aceh's freshwater shrimp resources.
