“…Os organismos meroplanctônicos que ocorreram na praia do Goiabal, são encontrados em diversos ambientes costeiros (ZIADI et al, 2015). Foi observado que as larvas de poliqueta, se destacaram tanto em densidade quanto em riqueza e foram registradas em todos os meses amostrados.…”

The density, the reproduction, and the larval development of meroplankton are directly related to food availability (phytoplankton), which in turn, mainly depends on nutrients concentration, on temperature, and salinity. This study aimed to make a survey of the meroplankton community of Goiabal Beach and analyze the quali/quantitative seasonal variations. The survey was performed in four samplings conducted between 2014 and 2016, and the samples were collected using a plankton net coupled to a flow meter. Two minutes' horizontal-superficial drags were performed, and the samples were fixed on 4% buffered formalin in 250 ml glass pots. Immediately after drags, the temperature, the salinity, and the turbidity were measured. After the analysis, six phyla were verified: Ectoprocta, Echinodermata, Annelida, Chordata, Arthropoda, and Mollusca. The most abundant larvae were the polychaete, and the density of the organisms varied importantly during the study.

Section: Temporal Patterns Of Oyster and Barnacle Recruitmentmentioning

“…Temperature is a major factor in the timing of the reproduction of barnacles and remains an important species-specific factor for spawning (Anil et al, 1995;Dattesh et al, 2006;Ziadi et al, 2015). The hatching peak of oysters often coincides with warmer water temperature, but barnacles often breed during relatively colder months and their larval peak is correlated to low temperature (Anil et al, 1995;Dattesh et al, 2006;Ziadi et al, 2015). The present study indicated that the barnacle recruited earlier and longer (early spring to early winter) than the oyster (mid spring to late fall), with two distinct recruitment peaks (mid-spring and mid-summer) that were separate from those (August) of the oyster.…”

Oysters and barnacles are dominant inhabitants of natural and restored oyster reefs around the world, and high areal coverage of barnacles at natural or restored reefs commonly decreases substrate accessibility for oyster settlement. The overall understanding of oyster and barnacle recruitment dynamics provides invaluable information on site selection and strategies employed for oyster reef restoration. This study documented the temporal and spatial patterns of oyster and barnacle recruitment on and near the largest natural intertidal oyster reef (Liyashan) in China during 2019–2020. The oyster Crassostrea sikamea recruitment appeared as a continuous process from June through late November or early December, with the peak in August. Greater recruits of oyster spat occurred on the sheltered inshore at the upstream of the natural oyster reef than on the reef and the nearby open coast (p < 0.05). The barnacle recruitment extended from spring to early winter, with mid-spring and mid-summer peaks. Conversely, higher barnacle recruitment appeared on the natural oyster reef and the nearby open coast than on the sheltered inshore. Across all the monitoring sites, the cumulative recruits of oysters in each of 2019 and 2020 was negatively correlated with those of barnacles (p < 0.05). The inshore sites (SH1 and SH2) with high oyster recruitment and low barnacle recruitment should be recognized as the natural spatfall sites for the natural oyster reef restoration. The separation in the recruitment peak between the oyster and the barnacle indicated that August was the most favorable window for capturing oyster spat through substratum addition to the water around the natural reef.

In the eutrophic Ghar El Melh Lagoon (GML, Tunisia), the distribution of heterotrophic prokaryotes, pico- and nanophytoplankton was studied at five stations in November 2012 at the single cell level, along with environmental factors. Flow cytometry analysis of ultraplankton (<10 μm) resolved (i) two heterotrophic prokaryote groups, low and high nucleic acid contents (LNA and HNA, respectively), and (ii) eight to nine ultraphytoplankton groups (cryptophyte-like cells, two nanoeukaryote subgroups, two picoeukaryote subgroups and three Synechococcus-like cells subgroups). Prochlorococcus was not detected. According to redundancy analysis (RDA), a significant difference was found in the distribution of the ultraplankton between stations (F = 2.61, p < 0.05); maximum proliferations of heterotrophic prokaryotes were observed in the inner parts of the lagoon at stations 3, 4 and 5 affected by urban, agricultural and industrial discharges. Ultraphytoplankton concentrations were the highest near the outlet of the lagoon at stations 1 and 2 influenced by freshwater outflow and oligotrophic Mediterranean water inflow, respectively. At station 1, the large ultraphytoplankton concentration derives from the high abundance of cryptophyte-like cells favoured by the freshwater outflow whereas at station 2, the input of oligotrophic Mediterranean water enhanced the abundance of Synechococcus and picoeukaryotes at the expense of nanoeukaryotes. Two trophic regimes were thus differentiated in GML.
