Abstract Vision ability has a important role for most fish larvae which are used to detect the presence of food. The success of feeding for fish in using visual aids in natural conditions depends on the background colour of the habitat. The purposed of study was to determine the effect of the background colour of the container on the growth and survival of bonylip barb larvae. This research wa…
ABSTRACT Chlorella sp. is a kind of phytoplankton that is used as natural source of food for zooplankton, such as fish larvae and shrimp. Chlorella sp. contains various nutriens that are good for the growth of fish larvae and shrimp. The success in cultivating Chlorella sp. is evidently closely related to the nutrien content given at the time of cultivation. One alternative cultivation of Chlo…
ABSTRACT Chlorella sp. has a pigment, namely chlorophyll-a which plays a role in the process of photosynthesis. Chlorella sp. culture requires nutrients and chlorophyll-a pigment to increase cell growth. Liquid organic fertilizer (LOF) Azolla sp. is expected to be able to meet the nutrients needed by Chlorella sp. This study aims to determine whether there is an effect of the use (LOF) of Azoll…
