A system for remediation of perfluoroalkyl substances (PFASs) has a multiplicity of β-cyclodextrins (β-CDs) and/or modified β-CDs combined with a vehicle additive, and a delivery device. Modified β-CDs can contain a single amine functionality at a single primary carbon or single secondary carbon of the β-CD. The vehicle additive can be powdered activated carbon (PAC). The delivery device is a column, a pouch, a packet, or a sheet that can permit the contacting of a fluid environment with the β-CDs and vehicle additive. The system of remediation can be used for a fluid environment or for biological organisms. CD-based fluorescent sensors can detect PFASs in the environment.

The present disclosure provides a method for artificial rearing of porcupine pufferfish fries in indoor cement ponds. The method includes the following steps: nursery pond preparation, ponding of newly hatched prelarvae, feeding strategies at fry rearing stages, water quality management during fry rearing, separate ponding of fries, and emergence of fries. Compared with the prior art, the method realizes large-scale production of artificial rearing of porcupine pufferfish fries through a strict control of the water quality and environmental conditions of a nursery pond, along with scientific and reasonable feeding and operation management based on biological characteristics and nutrient requirements of the porcupine pufferfish at different fry breeding stages.

The present invention concerns a method for obtaining conditioned fish models, and the use of same for characterising a cognitive impairment or deficiency, studying the brain regeneration capacity in a fish model, characterising the working memory and/or the cognitive capacities and/or the learning capacities in a fish model, and identifying molecules, compounds, compositions or formulations modifying the working memory and/or the cognitive capacities and/or the learning capacities in a fish model. The present invention also concerns a device for conditioning a fish model, the device comprising a tank (2) comprising a wall (5) delimiting a cavity (6) capable of containing water for the fish, the cavity (6) comprising a start zone (7) and a selection zone (8), a first partition (3) that can be moved between a closed position and an open position, a first display element (11) for displaying an instruction in the start zone (7), second and third display elements (12, 13) for displaying first and second responses.

Systems and methods for cultivating or accumulating climate-focused marine target products are described herein. The target product may be microalgae, macroalgae, plankton, marine bacteria or archaea, filter feeders (such as oysters or clams), or crustaceans either for the purpose of bioremediation, eventual cultivation or for sequestering carbon dioxide; or the target product may be direct chemical or biological accumulation of carbon or carbon containing organisms. The system is primarily a floating apparatus designed to hold the target product in a region of the water column and in a spatial region of the water where it will best accumulate target product mass. In some embodiments the system is designed to achieve eventual passive sinking (transformation from a floating to sinking apparatus) into the deep ocean. In some embodiments, the system is equipped with purpose-chosen sensors to instrument and quantify the various biological and mechanical processes occurring onboard.

An underwater camera system for monitoring fish in a fish pen is described. A stereoscopic camera may be used to determine dimensions of fish, and the underwater camera system may use the fish dimensions to estimate a biomass value of fish within the fish pen. The biomass value and rates of change of the biomass value may be used to adjust feeding of the fish in the fish pen. Images captured by the stereoscopic camera may be used to focus a variable focal lens camera on a fish to obtain high-resolution images that can be used for diagnosing fish conditions. Images captured by the stereoscopic camera may be used to predict motion of the fish, and the predicted motion may be used to generate various fish monitoring analytic values. The fish monitoring analytic values may be used to automatically control operation of the fish pen.
