Chitin was extracted from Polybius henslowii, a swimming crab, captured in large quantities throughout the Portuguese coast by purse seine vessels as bycatch. After standard chitin extraction procedures, water-soluble chitosan products were obtained via two different methods: (1) N-acetylation with addition of acetic anhydride and (2) reaction hydrogen peroxide. The chemical structure molecular weight derivatives, (WSC) chitooligosaccharides (COS), confirmed Fourier Transform Infrared...
Zooplankton and ichthyoplankton assemblages were studied from January 2003 to June 2004 in a temperate shallow estuary (Mondego estuary, Portugal). Monthly sampling was performed at five stations high low tides, with subsurface tows 335 500 µm mesh Bongo nets. Analysis of variance (ANOVA) showed significant effect (P < 0.05) the size net on abundance main zooplankton groups. On average, taxocenosis 67 102 times lower than tides respectively, especially south arm. More 80 species identified...
Abstract Interest on jellyfish research has significantly increased over the last two decades, mostly driven by potential benefits of their high‐end uses. Recent efforts have been put forward towards commercial use scyphozoan jellyfish, although pipeline leading to full exploitation is still at an early stage development. Indeed, further and several technical advances are required expand these bioresources a larger more sustainable scale. Here, we describe state art culture systems already...
In order to study the influence of physical forcing at different temporal scales, zooplankton was sampled a fixed station located mouth Mondego estuary (southern Europe). Samples were collected during diel cycles, over neap and spring tides. Zooplankton abundance diversity estimated for each sampling period. Holoplankton dominated by three taxa: Copepoda, with 48% total abundance, Cladocera (16%) Medusae (12%). Meroplankton occurred mainly as barnacle decapod larvae. Copepoda most diverse...
Anthropogenic CO2 emissions have led to the warming and acidification of oceans. Although, there is a growing evidence showing that simultaneous occurrence ocean are threats marine organisms, information on their combined effect coastal shrimp species remains scarce. The purpose this study was estimate effects seawater growth-related traits biochemical responses P. elegans juveniles. In work, were exposed for 65 days at 4 experimental conditions: pH 8.10 * 18 °C, 7.80 22 °C. results showed...
Among non-native copepods, the calanoid Pseudodiaptomus marinus Sato, 1913 is species probably spreading at fastest pace in European and neighbouring waters since its first record Adriatic Sea 2007. In this contribution, we provide an update on distribution of P. Mediterranean Black Seas, along Atlantic coasts Europe, English Channel southern North Sea. Starting from a previous overview, include here original recently (2019–2023) published data to show novel introduction different...
The temporal and spatial variability in population dynamics of the European crab Carcinus maenas (L.) was studied between June 2003 September 2007 Mondego estuary. An extreme climate event (extreme drought) occurred 2004 2005 with a low freshwater flow discharge into estuary, leading to an increase salinity. Juveniles' recruitment continuous throughout each year high proportion young recruits being recorded spring 2005. green crabs clearly increased from mouth upstream areas actually moult...
Seasonal and spatial variations in the composition relative contribution of harpacticoid species Mondego estuary (western Portugal) were studied based on a monthly sampling along salinity gradient. These benthic harpacticoids collected water column by means 63-µm plankton net. The influence hydrological parameters (temperature, salinity, oxygen dissolved concentration, pH, turbidity, chlorophyll- , total suspended solids nutrient concentrations) was analysed redundancy data analysis. In...
