“…Mating systems have numerous implications for the ecology and evolution of species due to the effects on population dynamics, effective population size ( Ne ), levels of inbreeding, and relatedness among individuals 1,2 . It is crucial to elucidate life history variation and reproductive strategies in exploited marine species for accurate stock assessment and sustainable fisheries management 3 and references therein.…”

Understanding life history variation and strategies is crucial for stock assessment and fisheries management due to the direct effects on population dynamics, effective population size, sex-ratios, levels of inbreeding, and relatedness among individuals. Aristeus antennatus (En ─ Blue and red shrimp; Fr ─ Crevette rouge; Sp ─ Gamba rosada) is one of the most exploited demersal resources in the Western Mediterranean Sea. However, information regarding the mating system and mate choice preferences remains largely unknown. Advances in molecular genetic markers and methods of inferring biological relationships among individuals have facilitated new insights into the reproductive dynamics of the species in the wild. Here, we used microsatellite markers to examine the A . antennatus mating system and putative mate choice preferences. Our results provided clear evidence of polyandry and polygyny. Relatedness analyses, together with F ST and DAPC values showed females exhibited a mating bias towards unrelated males. Mating males were inferred from spermatophores and suggested males were sympatric with females and were also from other spawning grounds. Our findings provided the first description of the reproductive behavior of blue and red shrimp.

“…In the Itá reservoir, for example, M. obtusidens was among the three most abundant species in terms of well-developed larvae (in the flexion stage) in a tributary with reservoir influence, indicating that pools and rapids in tributaries would function as habitats for the recruitment of migratory fish (Ávila-Simas et al, 2014). However, a broader view that considers the ecological relationships between the upper, middle, and lower parts of the Uruguay River suggest that the upper section can be considered a spawning area for some stocks of migratory fish (Reynalte-Tataje et al, 2012;Ribolli et al, 2015). Therefore, there is no clear evidence of recruitment for migratory fish in the upper Uruguay River.…”

Identifying spawning and recruitment areas of Neotropical migratory fish is an important conservation issue, because it allows to define connectivity between habitats used during the initial life cycle of these species. In this sense, the objective of this study was to delimit spawning and recruitment areas of three migratory fish (Megaleporinus obtusidens, Salminus brasiliensis and Prochilodus lineatus) along of an altitude gradient of the Uruguay River. Samplings of ichthyoplankton and juveniles were applied with five different fishing devices in four river stretches, one in reservoir and three in a free section, for two consecutive years (2015-2016 and 2016-2017), during the reproductive period of the species. Larvae and juveniles were not collected in the reservoir and, in the free section, larvae in the early stages of development were found only at an intermediate stretch, and the most larvae at more advanced stages (~80%) and juveniles (~95%) were recorded in the lower sampling stretch. Based on the larval stage and abundance of juveniles, spawning-recruitment connectivity sections were presumed for these migratory species. After, these sections were associated to the location of future hydroelectric dams in the study area, with possible negative implications for the conservation of these populations in the Uruguay River.

“…Males predominated in the school, in the proportion of five males to one female. Brito and Bazzoli (2003) observed a similar ratio in the São Francisco River, with three males to one female, and genetic studies have revealed that polygamy is common among some migratory fish, with a greater number of males per female (Ribolli et al ., 2016; Ribolli et al ., 2020).…”

The spotted surubim Pseudoplatystoma corruscans is a large migratory catfish native to the La Plata and San Francisco basins. Nonetheless, its reproductive dynamics and behaviour remain poorly understood. This brief note provides the first record of the mating behaviour of P. corruscans in natural conditions. This behaviour was observed in the main channel of the Middle Uruguay River (Brazil). A school of approximately 25 fish, 5 females (with protruding abdomen and larger body size) and 20 males, were followed and videotaped. The largest female led the school, followed by other fish. Some males disputed repeatedly the posterior region of the females, whereas other males continuously repelled them. Eventually, some males, apparently exhausted, floated belly up. During this event, males were in a state of pronounced agitation, and some had abrasions in the head. Polygamy characterized the mating behaviour of P. corruscans.
