The potential for freshwater aquaculture in West Kalimantan is still high, including one of them is the Nile tilapia (Oreochromis niloticus). The purpose of this study was to determine the optimal growth and best survival rate by a combination of Fish, Earthworm Pheretima sp. and Brown seaweed Sargassum spp flour. The method used is Completely Randomized Design with four treatments and five replications. The result showed that treatments with > 60% plant raw materials shows the best resulting not only growth but also survival rate. Feed with a combination of these raw materials showed an allometric positive growth pattern.
The Sinau Lake is one of the oxbow lakes in Kapuas Hulu, West Kalimantan, which will be used for various purposes, but limnological data is not available. The research objective was to obtain data on the structure of the phytoplankton community and the water quality conditions of Sinau Lake so that it could be used as preliminary data for management and utilization. Samples were taken using purposive sampling method. Water quality is still good with a high plankton diversity index, low dominance and high evenness. Water quality still support the life of aquatic biota or aquaculture.
West Kalimantan shows many reproductive events of Nereidid worms in estuaries.The Peniti and Karimunting estuaries become a Nereidid mass spawning site every year. Other estuaries such as the Kapuas river is also the one habitat of the Nereidid worm called the giant Nypa palm worm, Namalycastis rhodochorde. This species has a magnificent length in body size and popular use for fishing bait. The high demand for this worm causes habitat destruction and decreases the population in nature so cultivation efforts are important to do. Basic data encompassing habitat characteristics, reproduction, feeding, development, and larval rearing to enhancing cultivation has been obtained.Larval and juvenile stocking densities including aquarium installations are currently being studied in the laboratory. Further studies on harvesting techniques, specificpathogen-free (SPF) products as well as a sustainable production need to be carried outat industrial aquaculture level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
