00:00My name is Mohd Rizal Bin Solaji. I'm from Kuna, and now I'm working in the fisheries office in Tawau as a fisheries officer in Tawau.
00:17Our innovation this time is called IMTA, Integrated Multitrophic Aquaculture.
00:24It's more like an aquaculture system in a fish tank and in one area,
00:31to diversify the aquaculture.
00:33The idea came from Kuna, for example.
00:36It's a bit difficult to do it in one area.
00:39It's a very remote and fertile area with a tank system that we can see here.
00:43So we use this innovation to optimize the area with the aquaculture species.
00:49The aquaculture species can be selected based on the income of the farmers.
00:55For example, the one we're using now is the sea urchin on the surface.
00:59The main aquaculture species are the white fish, sea bass, and crab.
01:04These three species are not each other's predators.
01:07We also have the alatok, which serves as a fertilizer or provides additional oxygen to our aquaculture.
01:15On the bottom, we have the gamma and balak species.
01:19These species eat the rest of the food from the fish to reduce pollution in our aquaculture system.
01:28We also have the krang species, or we call it kimagergasi.
01:33Kimagergasi is usually used as a starting indicator.
01:36When it's alive, it means the area is very fertile.
01:39And kimagergasi is also used as a filter in the remaining food.
01:45From this size, which is about 150 grams, it takes less time.
01:53If the water is fertile, the fastest is 35 days to 45 days.
01:59But if the area is not fertile, it usually takes from 40 days to 55 days.
02:10Currently, the main problem for aquaculture is food and seeds.
02:17It is difficult to get seeds for now.
02:21There is a shortage of seeds, so we have to wait.
02:24The second problem is related to fish food.
02:29It is difficult to get daily fish food.
02:32We hope to work together and pray that this project will succeed.
02:39Because it has a positive impact on my business.
