Unobserved mortality occurs early in larval walleye (Sander vitreus) aquaculture

Frontiers in Aquaculture
One of the most persistent challenges in walleye larviculture is the high rate of unobserved mortality occurring within the first 30 days post-hatch. Walleye larviculture is characterized by high mortality rates, but oftentimes, only a fraction of the ...

Dietary soybean meal on growth and intestinal morphology of South American catfish, Rhamdia quelen, larvae Farelo de soja em dietas para larvas de jundiá (Rhamdia quelen) sobre o crescimento e morfologia intestinal

Ciência Rural, 2012
The effects of the replacement of bread yeast by soybean meal in diets for Rhamdia quelen larvae on growth, survival, and intestinal morphology were analysed. Larvae were fed for 20 days with five diets: a control diet formulated with 57% of bread yeast,

Replacement of broiler liver by fish meal and soy protein concentrate in diets for silver catfish (Rhamdia quelen) post-larvae

Journal of Applied Animal Research, 2021
Muscular growth in fish is influenced by diet quality, mainly the protein sources and amino acids balance. A feeding trial was conducted for a period of 28 days. Muscle growth and histology of Silver catfish post-larvae was evaluated.

The effect of water pH on the incubation and larviculture of curimbatá Prochilodus lineatus (Valenciennes, 1837) (Characiformes: Prochilodontidae)

Neotropical Ichthyology
Different pH levels of water in the incubation and larviculture of 'curimbatá' (Prochilodus lineatus) were tested to evaluate the effect of this variable on the survival and development of eggs and larvae. During incubation, pH of 5.0, 6.0, 7.0, 8.0, and

Ovarian development and early larval survival of Stenopus zanzibaricus (Bruce, 1976)

Frontiers in Marine Science, 2014
Despite economically valuable, ornamental shrimps are poorly studied and there is a lack of protocols for their captive breeding. Stenopus is one of the most important genera of ornamental shrimps, being Stenopus zanzibaricus one of the species with less

Sustainable replacement of fishmeal with Artemia biomass in diets for Nile tilapia (Oreochromis niloticus)

Aquaculture, Fish and Fisheries, Volume 6, Issue 6, December 2026.
ABSTRACT This study evaluated the effects of substituting fishmeal with Artemia biomass in aquaculture diets on growth performance and whole‐body composition of Nile tilapia (Oreochromis niloticus). Four dietary treatments were administered in triplicate to juvenile Nile tilapia (44 g) stocked in 1m3 cages in a pond at 30 fish per cage for 84 days. The

Comparative Performance of Kenyan and Imported Artemia in Early Larval Rearing of Clarias gariepinus

Aquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.
ABSTRACT Successful larval rearing of fish depends largely on live feed availability, during the critical first‐feeding stage. In Kenya, hatcheries commonly use phytoplankton or imported Artemia cysts as starter feeds, although locally produced Artemia is available. Hatchery operators' reports on low larval survival when using imported Artemia prompted
