This study was conducted from September 2024 to March 2025 at the Parasitology and Fish Diseases Laboratory, Faculty of Fisheries and Marine Sciences, University of Riau. The study aimed to examine the erythrocyte profile infected by the digenean trematode …
Trichogaster trichopterus is a freshwater fish commonly found in swampy and lowland waters, and it is highly valued for its taste and economic potential. However, in its natural habitat as well as in aquaculture systems, this species is often exposed to various environmental stressors that increase its susceptibility to parasitic infections. This research was conducted from September 2024 to Ma…
This research was conducted from November 19 to December 29, 2018 for at the Batam Marine Aquaculture Center (BPBL) located on the Trans Balerang Highway, bridge III, Setokok Island, Batam. With the research title the effect of different salinity on the growth and survival of stellar fish (Trachinotus blochii). The method used in this study is an experimental method with RAL one factor with 5 …
Asian redtail catfish (Hemibagrus nemurus) is a cultivated commodity that is widely cultivated in Indonesia. One of the cultivation systems used is without water replacement during the rearing period. This condition can cause ammonia from leftover feed and feces to increase in the rearing container. This study aimed to evaluate the effects of adding monosodium glutamate (MSG) on the liver perfo…
Jungga lime (Citrus jambhiri L.)/Sundai acid/Limau kuit is a natural ingredient that contains alkaloids, saponins, steroids, tannins, flavonoids, ascorbic acid, essential oils, and limonene which are antibacterial. This research was conducted from August 2024 until April 2025 at the Laboratory of Fish Diseases and Parasites, Faculty of Fisheries and Marine,RiauUniversity. This research aimed to…
Koi fish is a very common decorative fish comodity in Indonesia because of its beautiful color and the high pricing. Koi fish culture were commonly facing problem becuse of its slow growth and its high sensitivity on water quality, therefore a precaution to prevent it was done by using filtration system. Filtration system is a filtering process to remove dense particle and chemical substance in…
Asian redtail catfish (Hemibagrus nemurus) is an economically important freshwater fish in Indonesia with promising market prospects. A major constraint in Baung catfish aquaculture is the limited availability of seeds due to the low survival rate of larvae. One critical factor influencing the success of larval rearing is the provision of appropriate feed, considering aspects such as type, size…
This study aims to get the best stocking density of Climbing perch reared with a recirculation system using taiwanese mackerel biofilters. The method used was a 1-factor Completely Randomized Design (CRD) experiment, 5 levels of treatment and 3 replications, so that the experiment set amounted to 15 units. The treatments were P1 (48 fish/80 L), P2 (52 fish/80 L), P3 (56 fish/80 L), P4 (60 fish/…
Noni leaves (Morinda citrifolia L.) are a promising alternative plant protein source for aquafeed due to their relatively high crude protein content (15%– 22.11%). However, their high crude fiber content can reduce nutrient digestibility, necessitating appropriate processing to enhance their nutritional value. This study evaluated the effects of incorporating Rhizopus sp.-fermented noni leaf …
