DeJong Marinelife is also well-known for its wild coral and fish intake. With a focus on sustainability, they carefully source their wildlife while maintaining the integrity of marine ecosystems. This intake process is not just about quantity; it’s about quality and the health of the marine life they bring into their facility.
Innovative Fish Breeding Techniques
Fish breeding at DeJong is a marvel of modern aquaculture. They breed hundreds of species, utilising advanced techniques to ensure the health and viability of their fish populations. Their facilities feature large aquariums where different species coexist, providing a unique environment that encourages natural spawning behaviours.
Collection Box for Larvae
A particularly fascinating aspect of their breeding operation is the use of a collection box for larvae. This innovative device floats in the water, designed to collect fish eggs and larvae passively. It allows for precise species separation based on flow rates, ensuring that different types of fish can be bred without cross-contamination.
Culturing Phytoplankton and Zooplankton
Culturing your own phytoplankton and zooplankton is an exciting venture, though it can be daunting. At DeJong Marinelife, the process is taken to a professional level that guarantees clean cultures vital for maintaining healthy marine ecosystems. The meticulous sterilization techniques they employ ensure that their cultures remain free from harmful bacteria.
Every room dedicated to culturing is tiled from floor to ceiling, resembling a laboratory environment. Staff members adhere to strict biosecurity measures, including wearing boots and sanitising their hands multiple times a day. This level of cleanliness is vital for the success of their cultures, as even the smallest bacterial contamination can jeopardise the entire operation.
Their innovative approach involves using large plastic socks, which serve as culture vessels. These socks are heat-sealed and cut to start new cultures. However, the staff must frequently restart these cultures, as bacteria can eventually outcompete the desired species. It’s a fascinating glimpse into the dedication required for successful marine life cultivation.
State-of-the-Art Laboratory Facilities
DeJong Marinelife boasts impressive laboratory facilities that set them apart from typical operations. Unlike many smaller setups, their labs feature high-end equipment designed for serious scientific work. The HVAC systems maintain positive pressure, ensuring that only filtered air enters these spaces, creating a clean, controlled environment.
Inside, you’ll find sophisticated microscopes and advanced technology, including powerful industrial magnets used for separating brine shrimp larvae from their shells. This level of sophistication is rare and speaks volumes about their commitment to quality and innovation in aquaculture.
Advanced Aquaculture Techniques
When it comes to aquaculture, DeJong Marinelife employs techniques that push the boundaries of what’s possible. They are not only breeding a variety of fish but also experimenting with advanced methods like cryopreservation of larvae. This allows them to store and later hatch larvae when needed, providing flexibility in their breeding programmes.
For instance, they’re working on spawning sea urchins while also developing protocols for culturing phytoplankton that will serve as food for these larvae. The complexity of their operations showcases a deep understanding of marine biology and a commitment to sustainable practices.
Filtration Methods Used
Filtration at DeJong Marinelife integrates both modern technology and traditional methods. They utilise large commercial skimmers and filter rollers, which are essential for maintaining water quality in their extensive systems. However, what sets them apart is their strategic use of live rock as part of their filtration process.
While many aquarists fear introducing pests through live rock, DeJong has developed a comprehensive quarantine process to mitigate these risks. Their approach includes treating the live rock in a separate system for months, allowing any potential pests to starve while fostering a healthy microbiome.
The Role of Live Rock in Filtration
Live rock plays a crucial role in the filtration system at DeJong Marinelife. Despite concerns about pests, the benefits of using live rock—such as improved biological filtration and a more stable ecosystem—are undeniable. DeJong takes extensive measures to ensure that the rock is well-maintained and free from harmful organisms.
By quarantining the live rock and treating it much like a reef tank, they promote a healthy environment where beneficial bacteria can thrive. This process not only supports the filtration needs of their systems but also enhances the overall biodiversity within their aquaculture operations.
PEX Heating Coils in Sumps
One of the most innovative features of DeJong’s setup is the use of PEX heating coils in their sumps. This technology enables efficient temperature control across their systems. Unlike traditional heating methods, PEX coils offer a more streamlined approach to managing water temperature, which is crucial for the health of both fish and corals.
Incorporating PEX heating coils not only optimises energy efficiency but also contributes to a more stable environment for the marine life. The ability to recycle heat through advanced heat pumps further enhances their operational efficiency, showcasing how cutting-edge technology is being leveraged in marine aquaculture.
Feeding Techniques and Organisation
At DeJong Marinelife, feeding techniques are not just routine; they are meticulously organised to ensure optimal health for all aquatic species. The importance of balanced nutrition cannot be overstated, especially in a breeding operation where different species have varying dietary needs.
One of the standout features is their use of stainless steel food carts, which are kept in an ice bath to maintain freshness throughout the day. This setup allows for quick access to refrigerated seafood, ensuring that food is always ready when needed. It’s a practical solution that enhances efficiency, particularly for species requiring specific diets.
Each species has its unique feeding requirements, and staff members are trained to observe and adapt to these needs. For instance, when introducing new fish, they monitor feeding behaviours closely, adjusting food types accordingly. This level of attention ensures that the fish are not only fed but also thriving.
Additionally, labelling tanks with specific food preferences streamlines the feeding process. This simple organisational tactic helps staff quickly identify what each fish will eat, reducing waste and ensuring each species receives the right nutrition.
Large Animal Holding Facilities
DeJong Marinelife also boasts large animal holding facilities, providing temporary housing for larger species like sharks and manta rays. This capability is not only impressive but serves a practical purpose; they often offer their facilities as a "hotel" for public aquariums during renovations or exhibit upgrades.
