Increasing inputs of nutrients and organic matter from urban areas accumulate in coastal sediments, which act as a storage compartment that can trigger eutrophication events, and promote organism mortality. The aim of this research was to evaluate the factors that determine the distribution of nutrients in sediments and porewater from a coastal environment. Jurujuba cove receives nutrients and organic matter inputs from diffus...
The Atlantic chub mackerel ( Scomber colias ) became an important resource in purse‐seine fisheries of the Iberian Peninsula in the mid‐2000s. Being data‐limited at the stock level, 60 years of landings and 40 years of bottom‐trawl survey data were available for part of the area. A biomass model fitted to landings and survey data performed well under the assumption of homogeneous dynamics across the stock area. During 1993–202...
Comparisons of Hyperostotic Bones in Two Species of the Genus Oligoplites Gill, 1863 in the Southern Brazilian CoastNARA Subscribed
The description of skeletal disorders is commonly reported in fish species raised through aquaculture; however, wild marine fish may also exhibit high frequencies of anomalies, particularly the development of hyperostosis, a condition that causes thickening of the bones. Specimens of Oligoplites saliens ( n = 15) and Oligoplites palometa ( n = 14) were radiographed to verify hyperostotic bone occurrences. Hyperostosis was dete...
