INVE NATURA LARVAL FISH DIET
Rotifer substitution feed line composed of two formulations Natura pRo and ExL that provide hatcheries with superior nutrition to improve fry quality
Product Description
Improving fry quality and substituting rotifers requires top notch experience in larval feeds production and marine fish hatchery production. With Natura pRo and Natura ExL, INVE Aquaculture has achieved the right balance amongst ingredient selection, feed behavior and easy application in the commercial hatcheries.
CHARACTERISTICS
Our rotifer substitution feed line is composed of two formulations Natura pRo and ExL that provide hatcheries with superior nutrition to achieve the unthinkable.
Natura pRo
Natura pRo enables fish hatcheries to start dry feed application from mouth opening and achieve better performance in terms of fry survival and quality, reducing the dependency on rotifer variability in terms of quality and numbers.
- Reduces rotifer needs by more than 50%
- Balanced diet focusing on high quality fats and proteins
- Excellent behavior in water mimicking rotifers
- Highly palatable ensuring >90% success feeding rate
- Efficient nutrient assimilation by underdeveloped larvae
- Produced with innovative technology avoiding larvae tank pollution from dry feeds
- Available in 2 sizes pRo <100 (50 - 100 µm) and pRo 100 - 250 µm
Natura ExL
The target of quality does not stop with the rotifer phase supporting larvae with superior nutrition is key for optimal development and growth, with Natura ExL we have concentrated all our expertise to achieve higher standards in fry quality.
- Unique follow up for rotifer substitution
- Balanced diet focusing on high quality fats and proteins
- Securing optimal fry quality and robustness
- Highly palatable and digestible simplifying weaning process
- Optimal balance between quality larval nutrition and physical properties
- Available in 2 sizes ExL 200 - 400 µm and ExL 300 - 600 µm

Tentative feeding regime for Sea bream reared from hatching to juveniles
This feeding regime has to be adapted to local conditions such as the rearing system, temperature, fish density, etc. Initial 2 days old larvae density is 80 up to 120 larvae per liter. Temperature 18°C at day 3 rising up to max 20°C. Salinity 35-37 ppt. Photoperiod 14 16 hours daylight.
Tentative feeding regime for Sea bass reared from hatching to juveniles
This feeding regime has to be adapted to local conditions such as the rearing system, temperature, fish density, etc. Initial 2 days old larvae density is 80 up to 120 larvae per liter. Temperature 16°C at day 10 rising up to max 18°C. Salinity 35-37 ppt. Photoperiod 14-16 hours daylight.
Simple suggestions for successful rotifer substitution
Dry feed application targeting Rotifer substitution must have exceptional physical characteristics, behavior in water and the water quality must be kept optimal. Natura pRo and ExL can be easily integrated in marine fish hatcheries through our unique knowledge in producing top quality larval feeds and hatchery protocols development. INVE Aquaculture suggest the following water exchange rates and siphoning operations for optimal results.
| Water exchange in 24 hours* | Suggested Siphoning* |
|---|---|
| Day 4-7 (DPH) min 100 up to 150 | Day 6 post hatch |
| Day 8-18 (DPH) 200% | Daily as of day 8 post hatch |
*The suggested instructions need to be fine-tuned to local conditions especially to specific water quality issues, for technical advice contact your local INVE Aquaculture representative.
STORAGE / SHELFLIFE
Store in a dry place (max. 25°C). For prolonged storage and after opening, refrigeration (max. 5°C) is advised. Oxygen absorber included. Manufactured using natural ingredients. Color shade variation may occur but does not affect the product’s performance.
