Build a fish nursery and help the fish fry
Fish nurseries contribute to greater biodiversity in Lillebælt
A fish nursery contributes to greater biodiversity. The juveniles of different fish species can better hide from predators and crabs, increasing their chances of survival.
This has proven to be an effective way to protect and promote fish stocks in Lillebælt. These small protected areas, where fish fry can grow up without the threat of predatory fish and crabs, have helped to strengthen biodiversity in the area.
Fish nurseries act as safe nurseries where fish fry can find food in the form of small organisms like plankton and crustaceans. Hiding from crabs and predatory fish. This increases the chances of the fish reaching a reproductive age where they can reproduce themselves and contribute to the stability of the population.
Not only does it benefit fish stocks, but it also contributes to a healthier ecosystem by promoting a variety of wildlife that supports the natural food chains in the Little Belt.

How to make a fish nursery
A fish nursery consists of a wire mesh box with several chambers. Some are kept free, while others are filled with natural materials such as shells, branches, stones, seaweed and dead crabs found on the shore. After some time in the water, the fish nursery becomes covered with algae and small seaweed plants, creating a rich micro-habitat, or small habitat. This attracts more species than just fish fry. Aquatic insects, small crustaceans and other aquatic organisms also thrive, resulting in increased biodiversity and more life in the Little Belt.
Meet Brian
Brian is a nature enthusiast, founder and owner of Peninsula Nature.
He has always been interested in edible herbs and plants from nature's pantry.
Brian is a great communicator and seaweed safari hunter. He likes to talk about how to use our unique nature and at the same time take good care of it. About how sustainability, a better marine environment and healthy food can go hand in hand.
In recent years, he has focused on seaweed. This has meant that Peninsula Nature, together with other companies and also universities, participates as a partner in international projects working with seaweed as a resource for nature, animals and people.
Brian is currently focusing on spreading awareness of seaweed as a sustainable food in Denmark. Through workshops, seaweed safaris, courses and communal eating, he is working to get more people to eat more seaweed. Not just seaweed, but local seaweed, because in Lillebælt alone there are many native seaweed species that are pure delicacies.
Peninsula Nature is a company created out of a personal interest in sustainability and fascination with the nature that surrounds us, based on the Stenderup peninsula, in the middle of Nature Park Lillebælt.
Peninsula Nature is a trade and communication company working with seaweed.
Seaweed as a resource for improving the marine environment, protecting shallow water life, as an important part of the food chain from the bottom up, as a food ingredient and flavor enhancer, as a dietary supplement and much more.
What is a fish nursery?
A fish nursery is an initiative that aims to protect and promote the growth of young fish in natural water bodies. These are small ecosystems that act as natural nurseries for the fish. The concept has, here in Denmark, especially been implemented around the Little Belt.
A fish nursery consists of a lattice box that provides fish fry with shelter and hiding places when the small fish start to beat their tails in the early stages of life. In Lillebælt, the fish nurseries are made of natural materials that create hiding places for the fry. Fish can both hide and find food in the form of aquatic insects, small crustaceans and other small organisms that also thrive in the new habitats. The purpose of the fish nursery is to give the fish good opportunities for survival and to promote the overall biodiversity in Lillebælt. This is for the benefit of both animals and humans.
In Lillebælt Nature Park, fish nurseries have proven to be a highly effective tool for restoring and protecting fish stocks. The purpose of the fish nurseries is to provide the fry with a protected area where they can grow big and strong before heading out into the open waters. The small fish are often exposed to many dangers. Therefore, it is crucial to create an environment where the young fish can grow up in safety and gradually become stronger and more resilient.
An important effect of fish nurseries is their contribution to biodiversity. Creating a safe nursery environment for fish fry helps build stable and healthier populations of fish, which have a greater chance of growing and thus ensuring the survival of the species. Furthermore, fish nurseries contribute to a healthier and more diverse ecosystem as they also attract other species that depend on a varied and rich environment.
The fish nurseries in Lillebælt Nature Park are a shining example of how targeted nature conservation projects can help restore damaged or degraded ecosystems and promote biodiversity in local waters.
Fish nurseries are just one of several initiatives that together strengthen Lillebælt
We plant eelgrass
Eelgrass is an important marine plant as it provides food, habitat and hiding places for small fish in the belt and therefore plays a crucial role in marine biodiversity.

We regulate the crab population
The population of crabs in the Little Belt is far too high. By catching crabs, you benefit the ecosystem in the belt. The crab population needs to be regulated because it destroys the eelgrass and eats fish fry.

We put crab on the menu
It may sound a little wild, but eating crabs is one - tasty - way to get rid of them. You can make the ultimate crab bisque or crab pizza with fresh ingredients from Lillebælt.

We collect marine litter
If you pick up a bag at the reception at Gl. Ålbo Camping and hand it filled with marine litter to the camping dad, you'll get a free cup of cocoa in exchange.

We restore stone reefs
We re-establish stone reefs to increase the survival rate of fish fry. When we put rocks back on the seabed, nature itself starts to regenerate life and the results are impressive.

We create better spawning conditions
In collaboration with Havørred Fyn, local anglers and other nature enthusiasts, we establish spawning grounds and create the basis for new life in the river and thus more sea trout in the belt.
