Temporal and spatial distributions of four groups of larval fish assemblages based on the two-way indicator species analysis (TWINSPAN 

 program). (A) winter, (Bl summer and (C) autumn. 



hos Bank in the oceanic area. The taxonomic composition 

 of this subgroup was similar to that of the transitional 

 assemblage, but mesopelagic fish, such as Myctophidae, 

 Sternoptychidae, and Phosichthyidae dominated. 



The transitional assemblage found during the autumn 

 criiiso extended along the shelf break area from Royal 

 Charlotte Bank to the Vitoria Seamount (Fig. 9C). Its taxo- 

 nomic composition was predominantly Myctophidae, Scari- 

 dae, Gobiidao, Serranidae, Callionymidae, and Apogonidae. 



Oceanic assemblage The oceanic assemblage consisted 

 principally cif mesopelagic fish (Myctophidae, Phosichthy- 

 idae, Sternoptychidae, Paralopididae, and Gonostomati- 

 dae). The oceanic assemblage was found in the entire 



oceanic area from the Minei-\'a Seamount to Cape Frio 

 during the winter cruise. During the summer cruise the 

 same assemblage was limited to the oceanic area between 

 Vitoria and Cape Frio. The oceanic subassemblage was 

 detected over the outer continental shelf between River 

 Paraiba do Sul and Cape Frio, named the shelf-break 

 subassemblage. This group was represented by a small 

 number of taxa, predominantly Sternoptychidae. During 

 the autumn cruise the oceanic assemblage was located in 

 the oceanic area from the Roger Seamount to Cape Sao 

 Tome and consisted of Myctophidae. The oceanic subas- 

 semblage was identified to the south of the Abrolhos Bank, 

 and consisted predominantly of Myctophidae, Phosichthy- 

 idae, Scaridae. and Serranidae.
