“…The data obtained in the present study, concerning larval occurrence, confirmed the previous studies (e.g. Bonecker et al 1992Bonecker et al , 1993Katsuragawa et al 1993Katsuragawa et al , 2006Nonaka et al 2000;Bonecker and Castro 2006;Namiki et al 2007aNamiki et al , 2007bCampos et al 2010;Castro et al 2010;Goçalo et al 2011). Nevertheless, sampling in all previous studies in the region was restricted to the depth of 200 m. The possibility of collecting ichthyoplankton below the traditional depth limit was very important in showing that larvae of many species can be abundant in deeper regions as well, notably larval Cyclothone spp.…”

“…One of the pioneers, Matsuura (1971;1972), studied the life cycle of Sardinella brasiliensis (Clupeidae). Since then, other studies in Brazilian waters have considered the taxonomy of some families and the ecology, distribution, ontogeny and other aspects of the early life of fish (Bonecker et al 1992;Katsuragawa et al 1993Katsuragawa et al , 2006Nonaka et al 2000;Bonecker and Castro 2006;Namiki et al 2007aNamiki et al , 2007bCampos et al 2010;Castro et al 2010).…”

Studies on the vertical distribution of larval fish in water masses along the Brazilian coast are very rare. The present study aimed to identify larval fish occurring in the surface (1 m) layer and at depth in four water masses of the Campos Basin, southeastern Brazil: South Atlantic Central Water (SACW) (250 m), Antarctic Intermediate Water (AAIW) (800 m), Upper Circumpolar Deep Water (UCDW) (1,200 m) and North Atlantic Deep Water (NADW) (2,300 m). Material used in this study was obtained in 2009 through nocturnal horizontal stratified hauls using a Multinet (500 μm mesh size) during both rainy (February to April) and dry periods (August to September). A total of 10,978 fish larvae comprising 169 taxa were identified during the rainy (n = 6,015) and dry (n = 4,963) periods. The number of taxa decreased as the sampling depth increased. Larvae of Clupeidae, Engraulidae and Scombridae dominated in samples collected in the surface layer, while Sternoptychidae and Myctophidae were the most representative families in SACW. The other three water masses were dominated by Gonostomatidae larvae.

The growth and mortality rates of Myctophum affine larvae were analysed based on samples collected during the austral summer and winter of 2002 from south-eastern Brazilian waters. The larvae ranged in size from 2·75 to 14·00 mm standard length (L(S)). Daily increment counts from 82 sagittal otoliths showed that the age of M. affine ranged from 2 to 28 days. Three models were applied to estimate the growth rate: linear regression, exponential model and Laird-Gompertz model. The exponential model best fitted the data, and L(0) values from exponential and Laird-Gompertz models were close to the smallest larva reported in the literature (c. 2·5 mm L(S)). The average growth rate (0·33 mm day(-1)) was intermediate among lanternfishes. The mortality rate (12%) during the larval period was below average compared with other marine fish species but similar to some epipelagic fishes that occur in the area.

“…In ichthyoplankton surveys off eastern Brazil, Diaphus spp. larvae integrated the transitional and oceanic assemblages (Nonaka et al, 2000;Castro et al, 2010), and the numeric dominance of adults between 11-22ºS probably reflects the higher sampling effort in deeper waters when compared to 22-34ºS, where sampling was shallower (<500 m: Figueiredo et al, 2002).…”

“…Figueiredo et al (2002) and Santos (2003) reported 37 species captured in 133 midwater trawl hauls off southeastern and southern Brazil (22º-34ºS), with sampling effort concentrated from 100 to 500 m. From Rio Real, BA to Cabo São Tomé, RJ (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22) o S), 27 larval lanternfish species were identified in 658 samples collected in depths ≤200 m (Castro et al, 2010), and Myctophidae was the most diverse family at epi-and mesopelagic depths (Braga et al, 2007).…”

ABSTRACT. Twenty-nine species from 11 genera of Myctophidae were taken in daytime midwater and bottom trawl hauls off eastern Brazil (11 o -22 o S). Trawls were performed aboard the French R/V Thalassa to depths from 19 to 2271 m, including samples from shelf, slope and in the vicinity of oceanic banks and seamounts. Diaphus garmani was the most abundant species, accounting for 84% of all identified individuals and with four other species (D. dumerilii, D. brachycephalus, D. perspicillatus and Myctophum obtusirostre) accounted for >95% of all myctophids caught. Regarding longitudinal distribution patterns, 16 species are broadly tropical, seven tropical, three subtropical, two temperate and one amphi-Atlantic. For the most abundant and frequent species, highest abundances were associated mainly with cold waters, either South Atlantic Central Water or Antarctic Intermediate Water. Non-metric multidimensional scaling based on species presence-absence in the samples and oceanographic conditions was used to identify spatial distribution of myctophid assemblages. Three assemblages were identified in the studied area: north of Abrolhos Bank, south of Abrolhos Bank, and seamounts. Keywords: Myctophidae, fish assemblages, seamounts, southwest Atlantic.Peces linterna (Myctophidae) de la costa oriental de Brasil, Atlántico suroeste RESUMEN. Veintenueve especies de 11 géneros pertenecientes a la familia Myctophidae fueron recolectados mediante faenas diurnas de arrastre de fondo y arrastre de mediagua en la costa oriental brasileña (11 o -22 o S). Las faenas fueron realizadas con el buque oceanográfico Thalassa entre 19-2271 m de profundidad, cubriendo las regiones de la plataforma continental, talud, bancos oceánicos y montes submarinos. Diaphus garmani fue la especie más abundante (84%) y en conjunto con otras cuatro especies (D. dumerilii, D. brachycephalus, D. perspicillatus, Myctophum obtusirostre) representaron más del >95% de los mictófidos capturados. De acuerdo a los patrones de distribución longitudinal, 16 especies son de distribución tropical, siete tropical, tres son subtropicales, dos de zonas templadas y una anfi-Atlántica. Para las especies más abundantes y frecuentes, sus mayores abundancias estuvieron asociadas principalmente con aguas frías, especificamente con el Agua Central del Atlántico Sur y con el Agua Intermedia Antártica. Para definir la distribución espacial de las asociaciones de mictófidos basadas en la presencia y ausencia de las especies y su relación con las condiciones oceanográficas imperantes, se aplicó el análisis de ordenación MDS. Los resultados obtenidos indican la presencia de tres ensambles en el área de estudio: norte del Banco Abrolhos, sur del Banco Abrolhos y montes submarinos.
