Comment:
The PELDOcean cruise series were carried out by the Brazilian Program for Long-term Ecological Research (PELD) - Site 8 - Lagoa dos Patos Estuary and Adjacent Coastal Region. The activities aimed at the analysis of oceanographic conditions and ichthyoplankton in the coastal region under the influence of the Patos Lagoon (Muelbert, 2000). Three cruises were carried out, the first on 22 and 23/02/2000 (PELDoce_1), the second on 10 and 11/10/2000 (PELDoce_2) and the last on 05/02/2002 (PELDoce_3). Each cruise included a transect perpendicular to the coastline from the channel of the Lagoa dos Patos estuary towards the ocean, where 8 sequential hydrographic stations were carried out to characterize the oceanographic condition of the water column, followed by 5 complete oceanographic stations which included plankton trawls (Muelbert, 2000; 2001).
The ichthyoplankton samples were obtained through oblique hauls conducted from the bottom to the surface, with a 0.7 m diameter Bongo net with 330 ?m mesh equipped with flowmeters to determine the volume of filtered water in each trawl ( Muelbert, 2000, 2001). In the first and third cruises, the flowmeter was used only in the net A (Hydrobios cte = 0.263), and thus the values of eggs and larvae obtained for each net were summed to compose the totals of each station, and the filtered volume calculated for the net A used to standardize abundance values per 100 m3 of filtered water. In the second cruise, different flowmeters were used for each net (net A with Ictio2 cte = 0.4537769 and net B with Hydrobios cte = 0.263). As material from both nets was identified, the mean filtered volume by the two nets was used to standardize the abundance of eggs and larvae per 100 m3. Samples were fixed and preserved in formaldehyde solution, buffered with sodium tetraborate, diluted in sea water with a final approximate concentration of 4%.
