The invention focuses on the early fry culture, including algae, live-food organism, water quality control, fine image detection,automated intelligent culture technology. By connecting environmental parameter sensing equipment, fine image observation equipment, automatic feedback/delivering equipment,central intelligent learning/processing platform, an intelligent production system of aquatic fry can be completed,the big data on production parameters can be collected, optimizing breeding strategiesefficiency,increasing the breeding profitability more than 10 times.

We present pen-probe analyzers based on ion-mobility spectrometrymass spectrometry for in-situ detection of volatile organic compounds (VOCs)mapping of VOCs emanating from surfaces. User approaches probe to the analyzed object,presses a button on the probe. The collected data are uploaded to the Internet cloud for retrievalprocessing. Every data file contains the exact timegeographical co-ordinates of sample collection site. In another embodiment, the pen-shaped probe has been robotized to enable open-space samplingmapping of VOCs emanating from solid specimens.
