Obtain the highest growth rates for your rotifers
Provifeed®NannoPrime results in healthy, vigorous rotifers ready for the enrichment phase at high densities. The product contains freeze dried microalgae ensuring stable rotifer production (high fecundity) with high nutritional value (fatty acids, proteins, sterols, etc.) and inhibiting Vibrio spp. in the rotifer tanks. The product is ideal for rotifer batch, semi-continuous and continuous production. Provifeed®NannoPrime results in a high EPA level and high vitamin levels in the rotifers. These nutrients are not lost while harvesting and feeding to fish larvae. Using this rotifer culturing diet will save on costs and space, eliminating the algal production in the hatchery and are very easy to use.

Instructions for use
Preparation of the tank
Tank set up and optimal culture conditions
Add a maximum of 10 g Provifeed®NannoPrime per liter seawater and allow to hydrate for 5 minutes. Normally NannoPrime will easily disperse upon gentle agitation using a magnetic stirrer.
Alternatively blend during 2 minutes in seawater with a blender using a maximum of 10 gram per liter
Create a vortex first and then slowly add the Provifeed®NannoPrime to the water
Leave the product to rehydrate (5 min) and blend again for 1 minute
Sieve the suspension over a 50 µm sieve before feeding to the tanks
The homogenised feed can be stored up to 48 hours at maximum 4 °C. Shake before use
Feed the daily quantities in 4-6 rations or (semi-)continuously using peristaltic pumps
Apply the correct feeding regime depending on your culture strategy to assure the best production output and water quality
Depending on the quantities of rotifers required, it is possible to choose a strategy that will meet the demands of one’s system.
Starter rotifers should be clean, in good nutritional condition and have an egg-ratio of 20%.
The rotifer numbers illustrated in this feeding regime are indicative for Brachionus plicatilis clade L (‘L-type’) rotifers. Results can vary according to your culture conditions. Culture medium should be cloudy, very clear water may be an indication for underfeeding.
