REPUBLIKA.CO.ID, JAKARTA -- The Indonesian Ministry of Marine Affairs and Fisheries (KKP) has increased the seed stocks of parrotfish by developing a funnel system technology that continually circulates water and is believed to boost productivity.

"We have several fish cultivation areas that could be utilized for this. The technology by using a funnel system will be able to increase productivity and production of parrotfish," Fisheries Cultivation Head of the KKP Slamet Soebjakto noted in a written statement in Jakarta on Thursday.

He stated through the Technical Practitioner Unit of the Brackish Water Fisheries Cultivation Ujung Batee Aceh that the ministry has been successful in implementing the technology for fisheries, especially for parrotfish.

The unit was successful in developing the technology to increase the quantity of fish through a funnel system and availability of seeds, or juveniles, to meet the demand.

"This technology is purely developed by our local people. This technique utilizes a main device, a funnel-shaped one, which re-circulates water in a non-stop process," he stated.

He explained that in this method, the water current helps to prevent the fish eggs inside the funnel from sticking to each other, thereby helping to dramatically increase the hatching rate.

In comparison, the hatching rate achieved by using the conventional system only reaches 20 to 40 percent, while the funnel system could increase it to 90 percent.

"This high rate is an amazing achievement in the process of hatching parrotfish," he added.

Furthermore, Soebjakto revealed that the seeding technique by using this funnel system is an improvement on a similar technology used before for other commodities.

He cited the example of Plain Water Fisheries Cultivation in Gelam River in Jambi where the technology has already been successfully implemented to increase the cultivation of catfish.

"The innovative technology using this funnel system would hopefully be used by cultivators across Indonesia and the principle would also be applied for cultivating other fish species," Soebjakto stated.
