“…A similar pattern was observed in the back-calculated hatching dates of a wide size range of Kaupichthys leptocephali (Chlopsidae) collected around Sulawesi Island in the central Indonesian Seas ( Fig. 30; Lee et al 2008). However, estimated hatching dates of this genus corresponded to full moon periods.…”

“…A similar reduction in growth was seen in Kaupichthys leptocephali in the Indonesian Seas as they reached early metamorphosis ( Fig. 30; Lee et al 2008). It is possible that they may stop increasing in total length if they reach their maximum size while still offshore away from the appropriate cues to trigger metamorphosis.…”

“…Species collected in the mostly warm Indo-Pacific region have growth rates <1 mm/d and linear relationships between age and body length, with growth slowing down as maximum size is reached ( Table 1; . These relationships and the finding of apparent lunar cycles of spawning based on backcalculated hatching dates (Ishikawa et al 2001;Tsukamoto et al 2003;Lee et al 2008), suggest that increments are deposited daily in these species (Powles et al 2006).…”

“…Chlopsid eels have been suggested to have spawned over five consecutive months in the central Indonesian Seas based on analyses of otoliths from leptocephali collected in September ( Fig. 30; Lee et al 2008), but more research is needed to evaluate the spawning seasons of eels in tropical regions.…”

“…The periodicity of increments in otoliths of A. anguilla has not yet been validated experimentally, owing to difficulties in rearing their larvae beyond first‐feeding (Tomkiewicz et al., ; Sørensen et al., ). Nevertheless, we assume daily ring formation in A. anguilla for two reasons: (i) overall otolith microstructure is closely similar among many eel species (Correia, Isidro, Antunes, & Coimbra, ; Lee, Miller, Hwang, Wouthuyzen, & Tsukamoto, ; Kuroki et al., ), including both tropical and temperate anguillids (Leander et al., ), and (ii) Studies by Correia et al. () and Ma et al.…”

Growth rate variability of larval European eels (Anguilla anguilla) across the extensive eel spawning area in the southern Sargasso Sea

The European eel (Anguilla anguilla) spawns in the Sargasso Sea, and the leptocephalus larvae are distributed in the Subtropical Convergence Zone (STCZ), covering an area approximately 500 × 2,000 km in extent. The STCZ is hydrographically diverse and highly dynamic, which is likely to impact growth and survival opportunities of the larvae. Here we investigate the temporal and spatial growth rate variability of larvae collected along seven sampling transects across the STCZ during March–April 2014. Scanning electron microscopic analyses of otolith ring‐formations were used to estimate larval age‐at‐length, initial growth and growth trajectories. Analyzed larvae averaged 14 mm in length and 30 days of age. Age estimation indicated that the larvae were spawned during one continuous period, extending from mid‐February to late‐March, and that spawning had peaked during the new moon of 4 March. Growth estimates (average: 0.38 mm/day, ~6% weight increase/day) showed substantial variability among individuals. There were no apparent spatial trends in this variability, and no linkage to measures of temperature and salinity, while earlier‐spawned leptocephali showed slightly higher growth rates than later‐spawned larvae. The variability in growth rates at single sampling sites was as great as variability across the entire area of distribution. This indicates that individual growth opportunities are strongly impacted by variable conditions in the immediate environment while average conditions for larval growth and survival are basically the same throughout the immense area of larval distribution.

Remarkably little is known about the life histories of the many tropical anguillid eels distributed across the Indo-Pacific region, and since the Danish expedition to study eels in the region in 1928 and 1929, research on these eels has only begun again in recent years. Sampling for anguillid leptocephali in the Indonesian Seas has been carried out recently to learn about the spawning ecology and larval distributions of tropical eels there. The leptocephali of Anguilla marmorata, Anguilla bicolor pacifica, Anguilla borneensis, Anguilla interioris, and Anguilla celebesensis were collected around Sulawesi Island both in May 2001 and October of 2002. The development of genetic identification techniques has enabled these leptocephali to be identified to species, and their distributions and sizes during different seasons indicated that there are differing life history patterns among sympatric species in the region. A. celebesensis was found to have been spawning in Tomini Bay of northeastern Sulawesi Island in March and April 2001, but apparently, no spawning had occurred in the late summer and fall of 2002. Studies on anguillid glass eels have suggested that tropical anguillids may spawn throughout much of year, but our research on leptocephali in Tomini Bay and data on the downstream migration of tropical anguillids in the major tributary to Tomini Bay indicate that A. celebesensis may have a distinct seasonal pattern of spawning possibly related to the regional monsoon cycles. This is the first evidence of seasonality of spawning in tropical anguillid eels whose life histories are only just beginning to be revealed.
