“…However, age (DPH) and size (TL) were the best predictors of swimming performance (critical swimming speed and swimming endurance) for white seabream larvae. In the north-western Mediterranean Sea, several Sparidae larvae, including white seabream larvae, also showed significant relationships between critical swimming speed and body length [31]. However, other studies have found that body length was not the main factor responsible for critical swimming speed variability [30,33].…”

“…Most swimming performance studies have focused on tropical coral reef fish larvae [14,[21][22][23][24][25], while those focusing on temperate species have only increased in recent years [19,[26][27][28][29][30][31]. Comparatively to fish larvae of tropical species, temperate fish larvae are considered to be weak swimmers, swimming at slower speeds than tropical species [23,28,32].…”

The Sense Acuity and Behavioral (SAAB) Hypothesis proposes that the swimming capabilities and sensorial acuity of temperate fish larvae allows them to find and swim towards coastal nursery areas, which are crucial for their recruitment. To gather further evidence to support this theory, it is necessary to understand how horizontal swimming capability varies along fish larvae ontogeny. Therefore, we studied the swimming capability of white seabream Diplodus sargus (Linnaeus, 1758) larvae along ontogeny, and their relationship with physiological condition. Thus, critical swimming speed (Ucrit) and the distance swam (km) during endurance tests were determined for fish larvae from 15 to 55 days post-hatching (DPH), and their physiological condition (RNA, DNA and protein contents) was assessed. The critical swimming speed of white seabream larvae increased along ontogeny from 1.1 cm s−1 (15 DPH) to 23 cm s−1 (50 and 55 DPH), and the distance swam by larvae in the endurance experiments increased from 0.01 km (15 DPH) to 86.5 km (45 DPH). This finding supports one of the premises of the SAAB hypothesis, which proposes that fish larvae can influence their transport and distribution in coastal areas due to their swimming capabilities. The relationship between larvae’s physiological condition and swimming capabilities were not evident in this study. Overall, this study provides critical information for understanding the link between population dynamics and connectivity with the management and conservation of fish stocks.

“…In fact, analysing early‐life traits of D. sargus settlers in Marseilles (France) in 1994 and 1995, Vigliola (1998) find a mean PLD that is considerably higher than the one used in the present study (i.e., 28 vs. 16 days). Rossi et al (2019) observe even higher PLD with a mean of 40 ±5 days and ranging from 32 to 56 days in Corsica but explain this difference by the length of the fish at sampling (longer than 1 cm). In Spain, Macpherson and Raventos (2006) and Raventos et al (2021) find PLD ranging from 19 to 37 days (mean 27.6 ± 4.3 days) and from 14 to 32 days, respectively.…”

In bipartite life cycle fishes, spawning represents the onset of propagules dispersal, with eggs and larvae experiencing anisotropic transport and high mortality rates, before eventually metamorphosing and settling. Hence, early-life stages operate as bottlenecks for population demography by strongly constraining recruitment. Despite its significance, spawning is rarely explicitly considered in ecosystem management due to a lack of knowledge, for many species, about where and when spawning occurs. Previous evidences suggest that temperature is among the main drivers of spawning in Teleosts. Using the ecologically and economically relevant white seabream Diplodus sargus in the central Mediterranean Sea as a case study, we assess the abiotic factors that regulate the onset and duration of spawning and subsequent dispersal. Lagrangian backtracking simulations fed with early-life observations allow locating 11 spawning events, which are then associated to simulated temperatures ranging from 14.8 C to 20.6 C, in close agreement with previous estimates. Based on this range of suitable temperatures, we model the spatio-temporal variability of spawning success at broad-scale over 10 years (2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014) following the backtracking approach with hypothetical constant settlement areas. It highlights a prominent inter-annual variability in the Adriatic and Siculo-Tunisian strait driven by oceanographic processes. Moreover, a powerful clustering method uncovers relatively stable spawning areas in the Ligurian and Tyrrhenian seas with both early (January to Mid-February) and late (April to June) spawning peaks. Our methodology can be applied to other species and oceanic systems to investigate how oceanic processes impact spawning success, enabling the design of sound management strategies.

“…Endurance tests of raised gilthead seabream larvae of age 50 days showed that they could swim at a constant 12 cm s -1 speed during 42.2 ± 11.1 h, covering a mean distance of nearly 20 km (Faria et al, 2011). The critical swimming speed of larvae of ages 58 to 96 days collected at sea was recently estimated as 10.4 ± 1.7 cm s -1 (Rossi et al, 2019). The individuals collected here had similar ages and therefore probably also a significant capacity of movement, which they may have used to depart from drifting currents and swim to the coast and/or to remain close to the lagoon entrances, until they have developed sufficient ability to osmoregulate and sense lagoon waters.…”

To investigate dispersal and connectivity between spawning and lagoon nursery habitats of the gilthead seabream, Sparus aurata, in the Gulf of Lions (northwestern Mediterranean Sea), we modeled the potential transport of the species' larvae between its supposed main spawning site in the region (the Planier Island) and two of its main local nursery areas (the coastal lagoons of Thau and Salses-Leucate). Passive larval drift simulations using a dispersal biophysical model showed a large variability in the possible trajectories from spawning to nursery areas and in the predicted ages for larvae arrival on the two nursery sites. The most common ages at arrival obtained in the simulations (20-60 days) are broadly consistent with previous modeling studies but contrast with the actual ages of the S. aurata post-larvae collected in 2016 and 2017 at time of the lagoon entrances (60-90 days, from otolith readings). The period between 25 and 70 days being critical for gilthead seabream larvae to acquire sufficient swimming, osmoregulatory, and olfactory abilities to enter coastal lagoons, we argue that ontogenic development plays a crucial role in the transport and local retention of S. aurata larvae in the studied region, explaining the discrepancy between simulation results and observed data. Highlights ► We simulated dispersal and connectivity of the gilthead seabream in the Gulf of Lions. ► We estimated ages of larvae collected at the lagoon entrances from otolith readings. ► The most common ages at lagoon arrival obtained in the simulations are 20-60 days. ► The actual ages of collected larvae at time of the lagoon entrances are 60-90 days. ► Ontogenic development of seabream larvae likely explains this discrepancy.
