Indonesia’s public waters cover an area of 54 million hectares, and are the largest in ASEAN, consisting of 11.95 million ha of river waters and flood exposures, 39.4 million ha of swamp waters and 2.1 million ha of lakes and reservoirs and other bodies of water. such as ponds, reservoirs and lakes. It is estimated that there are 950 species of fish that inhabit Indonesia’s fresh waters and the results of research from the Palembang Public Water Fisheries Research Institute show that the waters of South Sumatra are inhabited by 233 species of fresh water fish, including economically important types for both consumption and ornamental fish. One of the fish endemic to public waters in Sumatra and Kalimantan is the hoven’s carp (Leptobarbus hoeveni ) (Kottelat et al., 1993).
Problem jelawat fish farmers are currently facing is the increasingly difficult time of obtaining seeds from nature due to uncontrolled intensification. One effort to maintain fish stocks in public waters is by re stocking fish in their habitat. From 2016 until now (2023) the Sungai Gelam Jambi Freshwater Aquaculture Fisheries Center (BPBAT) has played an active role in providing the availability of Hoven’s carp seeds by cultivating and spawning with innovative and adaptive technology and then the seeds produced will be released into public waters.
The aim of this activity is to provide fish seed assistance to stimulate fish cultivation activities, support increased production of aquaculture and to increase the stock of fish resources in public waters. Implementation includes brood care, spawning, seed care and seed distribution. The location for seed distribution in public waters must comply with applicable laws and regulations and be designated as a seed distribution location by the local government.
From the results of activities during 2020-2023, as many Hoven’s carp seeds have been released into the wild 3327000 fries. Distribution and release activities into public waters are carried out together with the relevant provincial services, members of Commission IV DPR and the Ministry of Maritime Affairs and Fisheries (Directorate General of Aquaculture)
