Marine Sciaenidae has a wide distribution, occurring in the Atlantic, Indian and Pacific oceans, and are considered one of the main fisheries resources in the world, being exploited extensively by some countries. In this context, the present work analyzed the evolution of the fishery production of the Sciaenidae between the years 1950 to 2015, considering the quantity produced, as well as the degree of vulnerability of the species, based on calculations of growth rate and variation of production, and estimated future yields. A total of 51 species belonging to 27 genera were identified, with production in 91 countries. The average annual production is 893413.5 tons, with China, India and Brazil being the countries that most capture croakers. It was observed that the production of Sciaenidae is growing at a rate of approximately 0.1% per year, but 24 species showed a negative growth rate, being Genyonemus lineatus, Atractoscion aequidens and Argyrosomus hololepidotus with-18% -16.4%, -13% respectively. Some species were noted in the catch variation, such as Pennahia argentata, which had a coefficient of variation of 149%. An aggravating exploitation of some species was observed, which may no longer be captured in the future. In 2025 a critical state is pointed out mainly for three species, and by 2050, five more are added to this worrying scenario. In this way, we need more studies on the biology, population dynamics and fisheries of Sciaenidae that will help in the sustainable management and conservation of them.
