Description

Incubator for breeding aquatic crustaceans Technical Field The present invention relates to a incubator for breeding (production) aquatic crustacean larvae. The invention also relates to a method for breeding aquatic crustacean larvae. Background Aquaculture methods for breeding fish typically use plant-based feeds. However, plant-based feeds have an impact on land farming, where the use of land, water and fertilizer is increased to produce feeds, all of which have their own environmental impact. Therefore, there is a need to replace plant-based fish feed. Biomass from the family of the hook shrimp is known to be useful as part of fish feed, but can also be used as health food and for human consumption. The unciaceae animal is a shrimp-like crustacean found throughout the norway coast. They are low nutrient crustaceans with high nutritional characteristics and the ability to grow under high density conditions. These organisms are known to grow in land-based units using inexpensive feed substrates. The land-based incubator is independent of environmental changes and can be adapted to the needs of the particular aquatic crustacean being bred. One of the major challenges in scaling up aquatic crustacean production to industrial scale is the separation of larvae from parents, as it is not uncommon for adult hook shrimp animals to eat their young children. Naturally, newly hatched larvae move downward toward the darker water bottom. They are far from the light to seek concealment and therefore far from the parent. The present invention addresses one or more of the above challenges of expanding the production of aquatic crustaceans to an industrial scale. Disclosure of Invention A cultivator for breeding aquatic crustacean larvae, wherein the cultivator comprises: -a main chamber; -a lower collection chamber arranged below the main chamber; wherein the main chamber and the lower collection chamber are separated by a perforated barrier and are in fluid communication with each other; wherein the main chamber comprises a light source configured to illuminate the main chamber; Wherein the main chamber comprises a water distribution unit configured to supply water to the main chamber; -a water outlet arranged in the lower collection chamber; Wherein the water outlet is configured to drain water from the lower collection chamber in a first state of the incubator; -a biomass outlet arranged in the lower collection chamber; wherein the biomass outlet is configured to drain water and larvae of the aquatic crustacean from the lower collection chamber in the second state of the incubator. Aquatic crustacean larvae and juvenile bodies have the same meaning herein and refer to aquatic crustaceans that have not yet reached adult form and size. In one aspect, a water flow is generated from a water distribution unit in the main chamber, the water flow passing through the perforated barrier into the lower collection chamber. In one aspect, the bottom of the main chamber is in fluid communication with the top surface of the lower collection chamber. In one aspect, the light source is disposed above the water level of the main chamber. In one aspect, the cross-sectional shape of the main chamber and the lower collection chamber is cylindrical, rectangular or square or any other shape. In one aspect, the shape of the lower collection chamber tapers from the top of the lower collection chamber to the bottom of the lower collection chamber. In one aspect, the biomass outlet is closed when the incubator is in the first state. In one aspect, the water outlet is closed when the incubator is in the second state. In one aspect, the size and shape of the perforated barrier opening allows movement of the aquatic crustacean larvae from the main chamber to the lower collection chamber and prevents movement of the aquatic crustacean from the main chamber to the lower collection chamber. In one aspect, the perforated barrier opening is circular, having a diameter of 10 mm a or less, such as 10 mm to 0.1 mm. In one aspect, the perforated barrier opening is circular, has a diameter between 1 and 6mm a, more preferably between 1.5 and 2mm a, and the aquatic crustacean is a phakidae animal. In one aspect, the aquatic crustacean is disposed in the main collection chamber. In one aspect, the incubator for breeding aquatic crustacean larvae is land-based. An additional light source may be provided which is at least partially submerged in the water below the water level. In one aspect, the additional light source is configured to illuminate the main chamber. The main chamber may be provided with a habitat for aquatic crustaceans, wherein the habitat may be tubular, wherein a major axis of the habitat is vertically oriented, and wherein a surface of the habitat may be perforated. The water outlet comprises: -a water filter; -a valve; -an overflow and an outflow; wherein, overflow structure controls the water level in the main chamber. In one aspect, the
