From nutrients to nutrition: nitrogen pathways and seafood nutritional quality in the Black Sea - a systematic review
The Black Sea's rich fisheries—particularly small pelagic fish and bivalves—are a vital source of protein, omega-3s, and essential micronutrients. However, ongoing environmental degradation raises concerns about the long-term nutritional value of this resource. A recent systematic review, adhering to PRISMA 2020 guidelines, reveals a critical knowledge gap: while broader nitrogen pathways are documented, direct biochemical measurements within key species like horse mackerel and anchovy remain limited.
Sex-related differences in the lipid and micronutrient profile, but not the proximate composition, of the Mediterranean mussel Mytilus galloprovincialis: a pilot study with implications for sex-targeted aquaculture
Bivalves represent a vital, sustainable source of protein and essential polyunsaturated fatty acids (PUFA), notably EPA and DHA. This pilot study of the Mediterranean mussel, *Mytilus galloprovincialis*, reveals significant sex-related differences in nutritional composition, despite comparable proximate values between male and female specimens. Notably, female mussels exhibited substantially elevated lipid content, PUFA fractions, and critical n-3 fatty acids, alongside higher levels of vitamin B12, iron, selenium, and iodine.
Legacy and alternative halogenated flame retardants in sediment and bivalves along Korean coast: geographic distribution, temporal trends, contamination sources, and ecological risk
A comprehensive analysis of sediment and bivalves along the Korean coast has revealed widespread presence of legacy and alternative halogenated flame retardants (HFRs), including PBDEs, HBCDDs, and novel compounds. Measured across 50 locations, contaminant levels correlated with proximity to industrial areas, harbors, and aquaculture. Observed shifts in HFR usage indicate a transition toward alternative chemicals, with BDE 47 and α-HBCDD exhibiting notable bioaccumulation potential. While risks from legacy compounds are generally low, localized concentrations of BDE 209 warrant concern.
