In May 2020 St. Zeeschelp, Fry Marine and Kingfish started a feasibility study on an innovative feeding system for fish larvae. The right amount of feed, the mix of feed and the timing of feeding is crucial for the survival of fish larvae and currently, there is no sufficient feeding system for this fish. Therefore, we investigate if it is economically and technically feasible to develop such system. An automated feeding system will ensure that the larvae receives fresh food with optimal...

For our fish larvae, we are always looking for the best solutions and innovations. We try to make the best environment and feed availability for them. We are now working on trials with automatic feeding. The goal is to have a complete live-feed system for all sorts of prey. With this we can ensure that our larvae, have always fresh and high quality live prey.

For our research project, together with Stichting Zeeschelp, we are looking to establish sole farming. Above a short video of a breakthrough in this project. We found a new live feed with very good results! Next step is to develop this further. Besides this, these fish are in a practical experiment to investigate a natural way to produce more female fish.

In our research projects we aim for innovation and improvement. This is an example of development and innovation in our raceway systems. We tried several inflow systems for our raceways. This is a new model; we are testing the flow, velocity and oxygen supply in the raceways. The first impression is very good, the fish are equally distributed over the basin and the feed uptake is sufficient!

This year we have done some trials with larvae rearing of Dover Sole. These trials were done in the context of the project 'Tongkweek Zeeland' and in cooperation with Stichting Zeeschelp. Next week we expect results from feeding trials and sex ratio in juvenile sole.... exiting! In the meantime we developed a new concept in sole larval rearing; shallow rectangle bassins. We did some trials with shallow larvae rearing with promising results! So we developed a recirculation system for larvae...

It's spawning seaons for our oldest broodstock fish at Fry Marine. The fish are 4 years old now and fully mature. This morning we stripped the fish and make the first fecudation of the season. It's always a very exiting job to do. In the next couple of days the fertilized eggs are kept in our incubation system. This system is specially designed to provide the eggs with best conditions to develop and eventually hatch. Next monday we hope to deliver this first batch into the larvae rearing...

Within the Sole hatchery project we are executing some interesting trials to improve the performance of the juvenile sole. In short we have found a mechanism that can influence the sex-ratio of the juvenile fish. We want to have more female than male fishes. When the fish is getting older, the females grow faster than the male individuals. In the experiments we are running at the moment we are looking to find the right moment and conditions to get the highest percentage of female fish.... and...

Developing ideas into practice, that's what Fry Marine stands for. So we started a new research project together with Seafarm. Goal of this project is to establish the complete production cycle for Solea solea. This means from broodstock to harvest. We believe this is possible in a profitable and sustainable way. Therefore we launched this project in the Innovation in Aquaculture program with funding from the EFMZV fund from the EU. First activities are already started. We are rebuilding the...

As mentioned in our last news update we had spawning turbot broodstock. It took some weeks to learn how to work with the fish in a good proper way. End of July we had a breaktrough with two good spawns. We obtained a lot of good fertilized eggs in a couple of days. These eggs were incubated in our system and developed very well. After 6 days the eggs were hatched. We placed them in our larvae systems. They received algae, rotifers, artemia and copepods. At the moment the larvae are in the...

Spring 2018 we did a small experiment on fish feed. In the project 'Broedhuis paling en tarbot: optimaal resultaat door kennisdeling' we worked together with TEMA on feed for (broodstock) turbot. It is difficult to test feed on broodstock, because it will take a lot of time te see any effect. So as a pre-study we used small turbot and we tested the effect of razor clams and shrimp shells on growth in a not-scientific test. First we had to try was whether the razors and the shrimp shells can be...
