Crayfish are a genus belonging to the freshwater crustacean group that has relatively high market demand. Red tilapia is a popular type of freshwater fish among both households and restaurant businesses due to its affordable price and high protein content. The polyculture system involves cultivating multiple species in the same pond, each with different dietary needs, thereby minimizing competi…
Pustina strain catfish is a fish produced based on a new variety in 2009 with a fast growth strain. One of the leading commodities favored by the public because of its economic value and high protein content. The adhesive of eggs become a factor in failure in cultivation efforts, so the eggs are soaked using an adhesive remover solution, namely a solution of Terminalia cattapa leaf extract, bec…
This research was conducted over a period of 40 days from February to April 2025 at the Aquaculture Technology Laboratory, Faculty of Fisheries and Marine Science, University of Riau. The study aimed to determine the optimal dosage of snail (Achatina fulica) feed for the growth and survival of snakehead fish (Channa striata) fry reared in a recirculating system, as well as to confirm the potent…
This research purpose was to determine the effect of applying biofloc technology on the reared of red tilapia in brackish water with different stocking densities and to determine the best stocking density of red tilapia reared in brackish water using biofloc technology. The method used in this research is the experimental method of Completely Randomized Design (CRD) with one factor 5 levels of …
Snakehead (Channa striata) is one of the popular freshwater commodities in Indonesia, but its cultivation is still relatively low due to its relatively slow growth. Biofloc technology that relies on microorganisms such as probiotic bacteria is a potential solution to increase cultivation efficiency. This study aims to evaluate the effect of using various types of probiotics in the biofloc sy…
The aim of the study was to determine the optimal doses of boster grotop in increasing the growth and survival of baung fish (Hemibagrus nemurus) in the recirculation system.

One of the economically valuable walking catfish species in Indonesia is Clarias batrachus. Due to high exploitation, this species may be at risk, making cultivation necessary. One of the key aspects of cultivation is the success of spawning. One of the applications of spawning is the use of hormones, and hCG is a hormone commonly used in fish spawning. This study aimed to determine the best do…
Quality feed is one factor affecting the growth and survival of Asian redtail catfish (Hemibagrus nemurus) larvae. Fish oil from pangasius catfish mesenteric fat waste can be commercial feed enrichment material. However, the high-fat content makes fish oil susceptible to oxidation.
