title: Long-term warming effect to sprat stock quality characteristics in Crimea-Caucasian shelf of the Black Sea
abstract: The Black Sea sprat Sprattus sprattus phalericus (Risso) and temperature factor impact have been investigated. Statistical assessment of the long-term dynamics (1951–2019) of a relationship between the temperature factor and sprat mean weight in fishery catches used as a population quality characteristic has been performed. Pearson product-moment correlation and cross-correlation was evaluated, then data series was smoothed by the local polynomial regression and, finally, a linear model was fitt
