Length-weight relationships are described for ten important demersal and pelagic fish species caught with bottom trawl: Merlangius merlangus, Mullus barbatus, Gobius niger, Alosa pontica, Spicara smaris, Scorpaena porcus, and midwater trawl: Engraulis encrasicolus, Sprattus sprattus, Trachurus trachurus, Pomatomus saltatrix from the Middle Black Sea. The samples sizes, minimum and maximum lengths and weights, length-weights relationships, ±95% CI of b, r2, growth type, and statistical analysis of the relationship between the sexes are summarized.
