Here are two general types of post larvae capture devices, namely crest nets and lights traps. Depending of the environment and the objectives of the project, a certain device type will be preferred to another.
The Ecocean team has tested and evaluated all of these devices, but we chose to focus our research and development on light attractors because they have the huge advantage of being usable in every coastal zone, from tropical to temperate and even to cold. We have therefore gained more than 10 years extensive experience of post-larval capture with this type of gear in over 20 countries. Those fishing devices can also be used in freshwater environment (lakes, bays , rivers…)
The following table published in the CPS review gives some helpful indications regarding choice of device.
Ecocean’s ground-breaking capture device, the CARE® (Collect by Artificial Reef Eco-friendly, patent process FR 2841742) is a fishing device designed for open ocean live capture of healthy post larvae. It is suitable for sampling the majority of cephalopod post-larvae, as well as any zooplankton, before their settlement in their permanent habitats. Our current CARE® device is the result of 10 years of continuous development and is now in its sixth version.
It is easily to handle and can be easily maintained and repaired by users in situ. Its compact size allows transport in any low-rise boat (sailing vessel, motor vessel, outrigger canoe, dugout, kayak, inflatable, etc.,), making it perfect for use by small-scale commercial, artisanal and subsistence fishermen in both developed and developing countries.
We can design custom made products specially adapted to your needs. The CARE® can also be delivered with options such as: timer, deepwater version, light variability, etc…
We also provide traditional plankton nets for scientific research. With a wide range of net sizes and mesh sizes, they can be used to validate the results obtained with our light traps.
We also provide turnkey nursery installations (or Wet Labs) made entirely from marine grade stainless steel, which can be configured and installed wherever you require, and can be fitted with aquaria and ancillary equipment according to your specifications. These are fully-equipped field laboratories in which you can rear all types of aquatic animals (marine or fresh water) according to your own requirements in order to effectively achieve your experimental goals. We also offer rental and leasing solutions for short and medium-term studies.
