High-Yield Species Property Spec Sheets
Essential biological parameters, stocking density limits, and target market prices for commercial culture fish.
Tilapia
OreochromisExtremely hardy, omnivorous surface feeders. Perfect for high-density Biofloc and RAS setups as they adapt easily to high turbidity and suspended solids.
Rohu
LabeoIndian Major Carp, highly popular in South Asia. A mid-water feeder, excellent for polyculture setups alongside Catla and Mrigal to optimize feed utilization.
Catla
LabeoA surface-feeding major carp known for rapid initial growth. Ideal for larger earth ponds where natural plankton blooms can supplement formulated feeds.
Pangasius
PangasianodonAn incredibly fast-growing river catfish. Possesses accessory air-breathing organs, letting it survive in highly dense, lower dissolved oxygen water profiles.
Magur
ClariasWalking catfish, fetches premium market prices due to delicious taste and high nutritional values. Prefers mud bottom setups or shallow intensive nursery tanks.
Shrimp
LitopenaeusPacific white shrimp, highly lucrative export product. Demands strict water biosecurity, steady salinity profiles (10-25 ppt), and high minerals for molting.
All Calculators Operations Center
Run immediate, precise operational calculations directly. Calibrate feed requirements, safe densities, and net profit projections.
Based on a standard 2.5% daily feed grow-out schedule split across 3 daily feeding cycles.
