In order to improve understanding of the larval migration and early life history characteristics of 4 tropical eels, Anguilla marmorata, A. bicolor pacifica, A. celebesensis and A. borneensis, the leptocephali, metamorphosing leptocephali and oceanic glass eels collected during 8 cruises in the western Pacific and Indonesian Seas from 1991 to 2002 were analyzed. The leptocephali of A. celebesensis and A. borneensis were collected only in close proximity to their relatively small species ranges in the Indonesian Archipelago and were found to have faster growth than the other 2 species with small-scale local migrations. The more widely distributed species A. marmorata and A. bicolor pacifica were collected in most sampling areas. Small leptocephali of A. marmorata were collected only to the west of the Mariana Islands, and only larger specimens, metamorphosing leptocephali, or oceanic glass eels of both species were collected in the Indonesian Seas. These distributions suggested that the 2 species have intermediate-scale migrations compared to other anguillid eels. The leptocephali of all 4 species appeared to reach a fully grown size of around 50 mm, which is considerably smaller than the maximum size of temperate anguillid leptocephali, and their growth was predominantly faster than that of temperate species. These data and recently derived molecular phylogenetic relationships among all anguillid species in the world suggest that the long spawning migrations of temperate eels evolved from much shorter migrations of tropical species, whose larval growth was faster and whose maximum larval sizes were smaller.

A similar spawning area in the South Equatorial Current (SEC) also appears to be used by A. australis from Australia and New Zealand (Jellyman 1987, Aoyama et al. 1999. Therefore, most temperate anguillids appear to have very similar large-scale migrations and spawn in areas that enable their leptocephali to use low-latitude westward-flowing currents such as the NEC and SEC to transport them thousands of kilometers back to their juvenile growth habitats .Recently, however, it has been shown that some tropical anguillid eels have much shorter local migrations and spawn over the deep waters adjacent to their freshwater growth habitats in the Indonesian Seas (Aoyama et al. 2003). The presence of small leptocephali of Anguilla celebesensis and A. borneensis near Sulawesi Island of central Indonesia indicated that these tropical eels do not migrate very far to spawn, because they have relatively small species ranges, with A. celebesensis being found from Sulawesi Island north through the Philippines and east to western...

“…Otoliths from 40 specimens (20 specimens in each species) were used for 'life-history transect' analysis of Sr and Ca concentrations, which were measured along a line down the longest axis of each otolith from the core to the edge using a wavelength dispersive X-ray electron microprobe (JEOL JXA-8900R), as described in Arai et al (1997Arai et al ( , 2001. Calcite (CaCO 3 ) and strontianite (SrCO 3 ) were used as standards.…”

The apparent use of marine and freshwater habitats by Anguilla australis and A. dieffenbachii was examined by analyzing the strontium (Sr) and calcium (Ca) concentrations in otoliths of silver eels collected from Lake Ellesmere, which is a shallow brackish-water coastal lagoon in New Zealand. The age and growth of these eels was also examined using their otolith annuli. Size and ages of females were greater than those of males for both species. Growth rates were similar among sex and species, but the highest growth rates were observed in eels that experienced saline environments. Line analyses of Sr:Ca ratios along a life-history transect in each otolith showed peaks (ca. 15 to 21 × 10 -3 in A. australis, 14 to 20 × 10 -3 in A. dieffenbachii) between the core and elver mark, which corresponded to the period of their leptocephalus and early glass eel stage in the ocean. Outside the elver mark, the Sr:Ca ratios indicated that eels had remained in different habitats that included freshwater (average Sr:Ca ratios, 1.8 to 2.4 × 10 -3 ), areas with relatively high salinities (average Sr:Ca ratios, 3.0 to 7.4 × 10 -3 ), and in some cases individuals showed clear evidence of shifts in the salinity of their environments. These shifts either indicated movements between different locations, or changes in the salinity of the lake. There were more individuals of A. australis that used areas with intermediate or high salinities, at least for a short time (85% of individuals), than A. dieffenbachii (30%). These findings suggest that these 2 southern temperate species may have the same behavioral plasticity regarding whether or not to enter freshwater or remain in marine environments, as has been recently documented in several northern temperate anguillid species.KEY WORDS: Anguilla dieffenbachii · Anguilla australis · Age · Growth · Otolith microchemistry · Habitat use · Lake Ellesmere · New ZealandResale or republication not permitted without written consent of the publisher

“…In this study, we found that the temperate eel A. japonica exhibited older metamorphosis timing and experienced a longer leptocephalus stage than the tropical A. marmorata. Arai et al (2001b) noted that this tendency was brought about by differences in the temperature experienced by leptocephali of temperate and tropical eels during their migration to coastal waters from their spawning areas. However, this might not be true for A. japonica and A. marmorata since they begin migration from the same general spawning area (Kuroki et al 2009) and drift with the same current system (NEC and KC).…”

Effects of metamorphosis timing and the larval growth rate on the latitudinal distribution of sympatric freshwater eels, Anguilla japonica and A. marmorata, in the western North Pacific

Background: Early life history traits of the temperate eel Anguilla japonica and tropical eel Anguilla marmorata were examined to determine the possible reason why these two species have similar spawning areas and oceanic larval transport in the North Equatorial Current and yet are recruited to different but partly overlapping continental growth habitats in northern East Asia. To understand the segregative migration of these two sympatric eel species, their glass eels were collected from nine estuaries in the Philippines, Taiwan, Japan, and China. The age at metamorphosis from leptocephalus to glass eel (T m ), the age at estuarine arrival (T t ), the time between metamorphosis and estuarine arrival (T t−m ), and the growth rate (G t ) of glass eels were calculated from daily growth increments in their otoliths. Results: Results indicated that the G t was faster and the T m was younger in A. marmorata than in A. japonica. On the other hand, fish length and the T t at estuarine arrival were larger in A. japonica than in A. marmorata, indicating that elvers of A. japonica experience a longer oceanic drift than those of A. marmorata. In addition, the T t−m also indicated that A. japonica experienced a longer coastal migration than A. marmorata.
