Aquaculture Feed Calculator

Fish farmers use the Aquaculture Feed Calculator to determine exactly how much feed their stock needs and what it will cost — removing the guesswork from daily feeding routines. Enter your number of fish, average weight per fish, fish species, water temperature, feed price per kg, and number of feeding days to get your daily feed required. Secondary outputs include feeding rate, total feed for the period, daily and total feed costs, and recommended feeds per day.

Frequently Asked Questions

How often should I feed my fish during the day?

Feeding frequency depends on fish size. Small fish (under 12g) should be fed 6 times per day between sunrise and sunset. Medium fish (12-50g) need 4 feeds per day, while larger fish (50g+) can be fed 2-4 times daily.

What percentage of body weight should fish be fed daily?

Feeding rates typically range from 2-8% of total fish biomass per day, depending on fish size, species, and water temperature. Smaller fish require higher feeding rates as a percentage of body weight.

How does water temperature affect feeding requirements?

Optimal feeding occurs at 26-28°C for most tropical fish species. Lower temperatures reduce fish metabolism and feeding rates, while higher temperatures may stress fish and reduce feed conversion efficiency.

What happens if I overfeed or underfeed my fish?

Overfeeding leads to poor water quality, increased disease risk, and wasted feed costs. Underfeeding results in slow growth, increased competition, and stressed fish that are more susceptible to disease.

How do I calculate feed conversion ratio (FCR)?

FCR = Total feed consumed ÷ Weight gain achieved. A lower FCR indicates better feed efficiency. Good FCR ranges from 1.2-2.0 depending on species and farming conditions.

Should feed size change as fish grow?

Yes, feed pellet size should increase with fish size. Use 2mm for small fry, 3mm for juveniles, 4.5mm for growing fish, and 6-8mm for mature fish to ensure proper consumption and digestion.

How can I reduce feed costs in aquaculture?

Optimize feeding schedules, maintain good water quality, use appropriate feed sizes, avoid overfeeding, buy feeds in bulk, and consider supplementary feeding with locally available ingredients under expert guidance.

What factors affect feed conversion efficiency?

Key factors include water quality, temperature, dissolved oxygen levels, fish health, feed quality, feeding frequency, fish density, and proper feed storage to maintain nutritional value.
