Lubukbasung, (Antara Sumbar) - The government of Agam District, West Sumatra, installed 1,521 tagging of floating net cages (KJA) in Maninjau Lake in an effort to inventory KJA's ownership.

"The installation of the tagging is done by jorong and nagari devices based on ownership done since June 2017," Head of Agam Fisheries and Food Crops, Ermanto stated in Lubukbasung, Tuesday.

Installation of the tagging has just finished about 50 percent of the total 1,521 units.

But it hopes the installation is completed by the end of the year.

"If the tagging is still lacking, then we will reprint based on the need," he added.

Besides, the serious effort reducing the number of floating net cages from 17,325 units to 6,000 units also be done, so that Maninjau Lake's pollution will decrease," he said.

Feed floating net cage fish is the largest contributor to lake pollution around 1,267,875 kilograms or 95.34 percent.

The rest, due to household waste at number of 61,728.38 kilograms or 4.64 percent, livestock waste 1,437.63 kilograms or 0.01 percent, agricultural waste 286.07 kilogram or 0.002 percent and forest erosion 106.4 kilograms or 0.001 percent.

"This pollution is caused by too many fish cultivators entering fish feed in order to get bigger fast. We will suck the remaining feed," he said.

Earlier, Head of Technical Implementation Unit of Agam LIPI Restorative Technique Medical Expert, Jojo Sudarso said that with the amount of fish feed sediments at the bottom of lake, oxygen is reduced and oxygen is only found at a depth of five meters.

With this condition, floating net cage fish, native lake fish and other biota will dead when the wind is strong.

"Currently, we only find 14 species of native lake fish and 34 species are already extinct," he added.

For that, this pollution must be overcome so that the native lake fish remain sustainable or exist.

"We have been cultivating bada fish, rinuak, asang and gupareh," fisherman said. "This fish will spread in the near future to the lake." (cha)
