title: Ichthyoplankton composition from PC-BELAP cruise 5, Southern Brazilian Shelf, in 1983

description: The PC-BELAP project was coordinated by Laboratório de Crustáceos Decápodos and Laboratório de Ictiologia of the Department of Oceanography of the Federal University of Rio Grande between the 31º49'S and 33ºS extending to the 60 m isobath in the years 1982 and 1983 ((Calazans, 1992; Ibagy & Sinque, 1995). Five cruises were conducted aboard NOc. Atlantico Sul, but in the first cruise (August / September 1982) no ichthyoplankton samples were analyzed. Plankton samples were collected with oblique trawls made from 1 m above the bottom to the surface with a conical 0.6 m diameter and 2.5 m long 330 ?m mesh-net coupled with a flowmeter (General Oceanics ) and a 20 kg hydrodynamic depressor. In shallow stations (i.e., with depths of 10 m or less), double oblique trawls were performed to increase the volume of filtered water (Ibagy & Sinque, 1995). The trawl velocity was estimated to be maintained between 1.5 and 2 ms-1 and vessel velocity constant at 1 ms-1 (approximately 2 kt) (Calazans, 1992). The samples were fixed and preserved in formaldehyde solution, buffered with sodium tetraborate, diluted in sea water with a final approximate concentration of 4%. The volume of filtered water was calculated and used to standardize the abundance of fish eggs and larvae per 100 m3. The identification of the eggs and larvae of fish was complete from the second cruise (November 1982) up to the 22nd station of the third cruise (January 1983). From the 23rd station of the third cruise the focus of identification was on the Clupeiformes and Sciaenidae.

title: Ichthyoplankton composition form PELDOcean cruise 1, Southern Brazilian Shelf, in 2000

description: 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%.

title: Ichthyoplankton composition form PRONEX cruise 1, Southern Brazilian Shelf, in 2005

description: The PRONEX series was obtained during two interdisciplinary cruises carried out in the scope of the "Programa de Apoio a Núcleos de Excelência" carried out in the winter of 2005 and summer 2007, in the regions near the Cape of Santa Marta (28º30'S) and Albardão (33ºS). Three transects were performed with the research vessel Atlantico Sul, totaling 15 oceanographic stations spaced 14 nautical miles (~ 26 km) apart in the Cape of Santa Marta, and 18 stations distant 17 nautical miles (~ 31 km) apart in the Albardão (Torquato, 2013). Ichthyoplankton samples were obtained continuously during the day and night by means of stratified hauls with a MultiNet containing 3 nets of 330 μm of mesh opening (nets 1, 3 and 5) and 2 nets of 200 μm (2 and 4), and mouth area of ​​0.25 m2. Two flowmeters, one internal and one external, were fixed in the MultiNet structure to measure filtration efficiency of the tow, and determination of the volume filtered in each haul with the internal flowmeter (Torquato, 2013). The MultiNet was lowered to the maximum depth of sampling with the first 330 μm net performing an oblique trawl. Subsequently, the MultiNet was towed back to the surface conducting stratified horizontal hauls at four different depth intervals. Ichthyoplankton was selected from the samples collected with the 330 μm nets (Torquato & Muelbert, 2014, 2015). The depth of each stratified horizontal trawl took into account the thermal and acoustic profile sampled at each station, so the depth of sampling varied between the oceanographic stations (Torquato, 2013). The samples were preserved in formaldehyde solution, buffered with sodium tetraborate, diluted in sea water with a final approximate concentration of 4%. The filtered volume was calculated and used to standardize the abundance of fish eggs and larvae per 100 m3 of filtered water (Torquato & Muelbert, 2014, 2015).

title: Ichthyoplankton composition form ARGO cruise 197, Southern Brazilian Shelf, in 1997

description: The ichthyoplankton component of the ARGO project was developed by the Laboratório de Ecologia do Ictioplâncton of the Department of Oceanography of the Federal University of Rio Grande. The objective was to gain further knowledge about the life cycle of fish in the shelf break and oceanic region adjacent to the South Brazil Continental Shelf. Six oceanographic cruises were carried out during the years 1996 and 1998 in the oceanic region and slope between 26º54'S and 34º30'S on the research vessel Atlantico Sul. The ichthyoplankton samples were obtained with oblique trawls made between the surface and 200 m above the bottom with a 0.6m diameter, 300 µm-mesh net coupled with a digital flowmeter. In the first cruise (ARGO_396) stratified trawls were made with a Kahlsico MultiNet containing 3 nets of 300 µm mesh opening and mouth area of 0.75 m2. Stratified vertical arrays were conducted in the last three cruises (ARGO_397, ARGO_198, ARGO_298) using a 0.6m conical-cylindrical, 140µm-mesh net with a closing mechanism. The samples were fixed and preserved in formaldehyde solution, buffered with sodium tetraborate, diluted in sea water with a final approximate concentration of 4%. The filtered volume was calculated and used to standardize the abundance of fish eggs and larvae per 100 m3 of filtered water (Muelbert et al., 1999; Franco et al., 2006).
