Abstract Turbot is one of the most valuable fish species in the Black Sea commercial fishery. The serious, dramatic depletion of the turbot stock and catches that began in the 1980s was caused by overfishing and poor ecological conditions. The state of the turbot stock began to improve in the northwestern part of the Black Sea in 2016. Landings were at their 30-year maximum in this part of the sea. Catches per unit effort (CPUEs) have been at a stable, high level there for the last few years. Average turbot weight and length have also been increasing. The Stock Synthesis (SS3) framework was used in the stock assessment. According to SS3 analysis, fishing mortality (F) reached the minimum level of 0.29 in 2018. The cumulative SPR (Spawner Potential Rate) index was 0.27, which approximately equaled SPRMSY = 0.25. Thus, currently the turbot stock is mostly moderately exploited at a level close to the management target in the northwestern part of the Black Sea. However, the entire Black Sea population has not fully recovered yet.

The present investigation covered 400 specimens of Platichthys flesus and 22 of Scophthalmus maximus caught in the period of October 1993-December 1994 in the Gulf of Gdańsk (the South-east Baltic). The following parasite species were found: Bothriocephalus scorpii, Hysterothylacium auctum, Cucullanus heterochrous, Cuculanellus minutus, Anisakis simplex, Raphidascaris sp. (probably R. acus), Echinorhynchus gadi, and Pomphorhynchus laevis. The occurrence of parasites was studied in relation to the season of fishing and the length of the fish body.

This book resumes many years of research experience of the authors and their colleagues, as well as numerous European and Chinese experimental and field studies on the developmental biology and physiology of valuable commercial fish, the Black Sea kalkan (Scophthalmus maeoticus) and the Atlantic turbot (Scophthalmus maximus), closest relatives and, according to modern genetic research, presumably, one species. The history of formation of currently powerful industrial turbot aquaculture presented in this book is based on the analysis of numerous scientific and applied research on turbot mariculture and economic features of formation of its European, in particular, Spanish and Chinese clusters. Recommended for researchers – biologists and biotechnologists, university professors, students of biological and biotechnology specialties, specialists in aquaculture, fish farming, ecology, as well as for a wider range of readers, managers, economists and operators of aquaculture enterprises.
