“…However, schools of juveniles (< 30 mm L T ) also inhabit surf zones (Oliveira et al, 2014(Oliveira et al, , 2018Rodrigues et al, 2015). This surf-zone life stage may last for >1 year and apparently gives juveniles a better chance to move into estuaries to complete their development (González Castro et al, 2011;Jaureguizar et al, 2003;Lima & Vieira, 2009;Oliveira et al, 2014Oliveira et al, , 2018. Our results and those of Fortunato et al (2017) suggest that approximately 10% of the population does not always use estuaries as nurseries and can complete its entire life cycle in the marine environment.…”

“…After the larval stage, mullet juveniles are recruited to the estuarine nursery area (Vieira, 1991). However, schools of juveniles (< 30 mm L T ) also inhabit surf zones (Oliveira et al, 2014(Oliveira et al, , 2018Rodrigues et al, 2015).

“…Mugil liza eggs and larvae are neustonic, but before recruitment to the estuarine environment, juveniles under 30 mm L T temporarily occupy surf zones (Rodrigues et al ., ; Vieira, ). This surf zone life stage, which may last for over a year, gives juveniles under 30 mm L T a better opportunity to enter estuaries, where growth and survival may be improved (Castellini et al ., ; Oliveira et al ., , ; Rodrigues et al ., ; Vieira, ).…”

We analysed the ratios Sr:Ca and Ba:Ca in the otoliths of 55 adults of the southern population of Mugil liza in Brazil (Paraná to Rio Grande do Sul) to investigate its coastal zone use and migratory behaviour. All individual M. liza analysed had Sr:Ca and Ba:Ca values indicating that their birth was in the marine environment, which is consistent with the southern population migration to spawn in the ocean,. Juveniles exhibited at least three coastal use and recruitment strategies (contingents): the majority (89%) of M. liza juveniles migrated toward brackish water. They entered the estuary before completing the first year of life (64%) or after (25%) their first year of life. The remaining 11% did not appear to enter brackish or freshwater water as a nursery or at any point in their life cycle. Some adults returned to the estuary after spawning in the ocean but others (of both sexes) never returned to the estuary after spawning, remaining in the marine environment. The pattern of juvenile habitat use in the Brazilian southern population of M. liza seems to be recurrent throughout the extent of its distribution as a consequence of the reproductive spawning aggregation behaviour, which mixes all contingents (with marine or estuarine preferences).

“…Oliveira et al (2014) investigated the role of mullets in transport of marine nutrients into the freshwater food webs in one of the coastal streams studied by Bastos et al (2013Bastos et al ( , 2014. In this same system, Oliveira et al (2018) verified the use of freshwater habitats by juveline mullets through the analysis of otolith chemistry.…”

Composition, abundance and biomass of a fish assemblage in a southern Brazilian coastal stream during polyhaline/euhaline condition

The coastal streams of southernmost Brazil, Rio Grande do Sul state, are marked by a period of regular marine intrusion resultant from intense oceanic winds. In the present study we aimed to investigate the species composition, abundance and relative biomass of the ichthyofauna in the lower stretch of a coastal stream during summer, a period of regular marine intrusion. Estreito is a coastal hydrological complex composed by lakes, swamps and a perennial stream, located at the central-south portion of the coastal plain of Rio Grande do Sul state. During the summer of 2018, the ichthyofauna of lower Estreito stream was sampled by beach hauls applied in 17 random points distributed in a stretch of ca. 2km. Measurements at the sampled stretch revealed salinities between 19.3 to 31.3 ppt, characterizing the studied system as polyhaline/euhaline during summer. The sample of 4,533 specimens revealed the occurrence of 20 species, being the great majority marine-dwelling. The most abundant species were the anablepid Jenynsia lineata (70.3%), the cichlid Geophagus brasiliensis (19.3%) and the the mugilid Mugil curema (7.5%). The highest relative biomass was recorded for J. lineata, followed by M. curema and G. brasiliensis. The dominance of marine-dwelling species in the assemblage composition and the high abundance of limnic-estuarine J. lineata corroborate previous studies conducted in other washouts of Rio Grande do Sul.
