Anthropogenic activities have been shown to significantly affect marine life. Water pollution and oil spills are particularly deleterious to the fish population, especially during their larval stage. In this study, Sobaity-sea bream Sparidentex hasta (Valenciennes, 1830) larvae were exposed to serial dilutions of water-accommodated fraction of Kuwait crude oil (KCO-WAF) for varying durations (3, 6, 24, 48, 72 or 96 h) in acute exposure regime.

Heavy metal pollution can adversely impact marine life, such as crabs, which can accumulate it in different organs and potentially transfer and biomagnify along the food chain in aquatic ecosystems. This study aimed to examine the concentrations of heavy metals (Cd, Cu, Pb, and Zn) in sediment, water, and crab tissues (gills, hepatopancreas, and carapace) of the blue swimmer crab in the coastal areas of Kuwait, northwestern Arabian Gulf. Samples were collected from Shuwaikh Port, Shuaiba Port, and Al-Khiran areas.

(Valenciennes, 1830) of the Sparidae family, is an economically important fish species. However, the genomic studies on are limited due to the absence of its complete genome. The goal of the current study was to sequence, assemble, and annotate the genome of that will fuel further research related to this seabream.

Article Synopsis
  • The study investigated trace metal concentrations (Cd, Cu, Pb, Zn) in phytoplankton, zooplankton, and seawater off Gabès, Tunisia, revealing significant pollution due to decades of fertilizer processing.
  • The Gulf of Gabès showed metal concentrations in seawater exceeding other Mediterranean regions, with the order of metal prevalence being Zn > Pb > Cu > Cd in water and phytoplankton, while zooplankton showed Pb > Zn > Cu > Cd.
  • Biomagnification rates indicated that Zn and Pb accumulated more in zooplankton than in phytoplankton, whereas Cu and Cd had higher biomagnification in phytoplankton.

This baseline study highlights the Po and Pb concentration in seven macroalgae species from the northern Gulf that are frequently washed ashore during the bloom season from February to April. The highest concentrations of Po and Pb were 2.947 ± 0.
