Study differentiating fish oocyte developmental stages using bioimpedance spectroscopy

Fish oocyte development monitoring is a mandatory operation when studying breeding in captivity as well the wild. In aquaculture, it required to determine best fertilization time. wild, helps detect spawning grounds, distribution of fish species and interaction between animals their environment. both settings, conventional technique for developmental stage identification consists handling sampling sample observation using binocular zoom head. Such an difficult operator fish. There need repeated anesthesia sampling, relies on expertise identify stage. this context, publication proposes, first time, study potential bioimpedance measurement alternative studies. We have set up experiment combining vitro sampled oocytes with estimation 69 collected farmed European sea bass. The statistical analysis has demonstrated that three four main stages can be identified measurement. integrability its implantable sensor makes approach very promising. Thanks could possible, time ever, monitor vivo
