Special Issue Information

Dear Colleagues,

The worldwide loss of biological biodiversity continues unabated, with the main causes being habitat destruction by various natural and anthropogenic threats, such as over-harvesting. The unrestrained exploitation of marine resources can adversely impact certain elements of the marine environment and the interrelationships created within biocenoses. It is for these reasons that scientific research of industrial marine fishing has undergone an increase in both its frequency and intensity in recent decades. Knowledge about and the mapping of fishing areas is important for the development of pertinent strategies and the management of fisheries. Research and mapping should be conducted by season in order to capture the impact of diseases on living organisms, which can be an important indicator for achieving sustainability in fisheries management. This is a goal that ultimately requires ensuring a healthy environment for populations in the regions of interest and maintaining a biologically diverse marine ecosystem that contains naturally viable populations of higher organisms, including marine mammals. In this regard, for the rehabilitation of ecosystems, such as the Black Sea, and the creation of sustainable fisheries, management policies pertaining to these activities need to be improved. Moreover, fishing efforts need to be continuously adjusted according to the physical state and health of fish stocks. The stock evolution of the main commercial fish species depends, above all, on the activity of industrial fishing, but just as important is the state of the fish population’s health.

Until recently, the smooth scallop Flexopecten glaber (Linnaeus, 1758) was considered absent from Romanian Black Sea waters, as only isolated valves were documented on beaches of the southern coast. Yet, in 2020, the first living specimens were collected by dredging at 25 m depth in Mangalia. Moreover, in the past three years, a considerable number of live individuals were also retrieved from beam-trawling operations targeting the gastropod Rapana venosa (Valenciennes, 1846) along the Romanian coast, indicating that there is a stable population here. This remarkable expansion of F. glaber in Romanian waters may be explained as a consequence of the Black Sea’s recovery from eutrophication, reduced predatory pressure from the declining population of R. venosa and changing climate conditions. Our research aimed at using all this novel information to document for the first time the occurrence and distribution of this bivalve on the Romanian coast, also considering perspectives for the development of a new type of shellfish mariculture, avoiding any pressure on the natural stock. In total, 386 F. glaber individuals were sampled during 2020–2023, at depths between 22.5 and 33.3 m. The abundance and biomass per station oscillated between 5 and 319 specimens and 51.5 and 7377 g, respectively. A subsample of 122 specimens was preserved and analyzed in the laboratory, revealing an average shell length of 53.54 mm (±4.13 SD) and an average shell height of 49.54 mm (±3.64 SD). The smooth scallop has both ecological and economic value, which makes it a viable candidate for sustainable aquaculture by collecting spat from the most abundant areas and subsequently placing “seedlings” in the appropriate polygons for stock recovery. Ultimately, commercial exploitation from aquaculture installations can be considered, provided a permanent healthy F. glaber population is established on the Romanian coast. Full article
