  Fish provide essential nutrients—high-quality proteins, omega-3 fatty acids, and vital vitamins—making them a key component of human nutrition. Previous studies have indicated that consumers prefer wild over cultured fish; however, whether real nutritional differences exist remains unclear. This paper reviews 41 studies on quality differences between wild and cultured fish across 27 species, examining proximate composition, minerals, fatty acids, amino acids, color, and texture. Cultured fish had a significantly lower moisture content but a higher lipid content, while the protein and ash contents showed no significant differences. Cultured fish sometimes exhibited lower polyunsaturated fatty acid percentages. Both groups were mineral-rich, though wild fish contained significantly higher toxic element levels. Color and texture differed substantially by origin. These results suggest both cultured and wild fish possess valuable quality attributes. Variations likely depend on sex, diet, region, season, farming mode, and environmental conditions. Although the core synthesis covers literature until November 2019, selected key studies from 2020-2024 were integrated to reflect recent developments, corroborating and refining the overall conclusions. This review offers insights for sustainable aquaculture quality development.

  Depuration is a widely used post-harvest technique to reduce contaminants in shellfish. However, its effects on the nutritional quality of blood cockles (Anadara granosa) in the removal of microplastics (MPs) are not well understood. This study aimed to assess the changes in the biochemical composition of cockle meat during a five-day MP depuration process. Cockles were subjected to a controlled depuration protocol, with samples collected at day zero, three, and five for analyses of MP abundance and biochemical composition. Standard methods were used to determine the MPs, proximate composition (including ash, proteins, lipids, and carbohydrates), and mineral content (Ca, Mg, P, and Fe). The results showed that the five-day depuration period effectively reduced the mean MP load by 71.6%. The process removed larger MPs and films, resulting in a higher relative abundance of smaller MPs (<500µm) and fibers. However, this process resulted in a statistically significant decrease in the biochemical composition of the cockles. By day five, the contents of biochemical composition had declined significantly. These findings demonstrate that while depuration is an effective process for reducing MP contamination in A. granosa, it decreases the nutritional quality.
