“…Mouth gape size of L. plumbeus larvae and SL show a linear relationship. This observation has also been reported in golden perch (Arumugam and Geddes, ), silver perch Bairdiella chrysoura (Waggy et al., ), Florida pompano (Riley et al., ), and dusky grouper (Russo et al., ). The Australian silver perch (Bidyanus bidyanus ) larvae also have a small mouth gape of 400 μ m and are 5 mm in TL at first feeding (Arumugam and Geddes, ).…”

Summary This study examined the diet composition, feeding preferences, and mouth morphology of the silver therapon (Leiopotherapon plumbeus, Kner 1864) larvae under captive conditions. Larvae were reared in outdoor tanks (4 m3) with natural food grown 2 weeks prior to start of larval rearing. Food preference was measured by the Chesson's electivity index (αi). Gut content analysis of larvae sampled between 5 and 25 days after hatching (DAH) showed the dominance in the diet by zooplankton, mainly copepod nauplii, cladocerans and insect larvae. Small fish larvae (5–9 DAH; 3.32–6.29 mm standard length) preferred cladocerans, ciliates and copepod nauplii; whereas older larvae (12–25 DAH; 5.45–19.26 mm standard length) preferred insect larvae over cladocerans and adult insects. The mouth gape size at 5 DAH was 359 μm and increased to 3.75 mm at 40 DAH when body size grew at an average rate of 0.59 mm d−1. The standard length (SL) of L. plumbeus larvae was strongly associated with mouth size (r2 = 0.98, P < 0.05), indicating a progressive increase of ingested prey size of the fish larvae. These results clarified the early life feeding ecology of this species, which is essential in developing effective hatchery techniques.

“…However, during our sampling campaigns, adults were caught off the Carmen Island, demonstrating that the species can live at sea and that adult population in the lagoon could be mixed with other. Moreover, Waggy et al (2007) reported larvae from this species in the marine plankton in the northecentral Gulf of Mexico, suggesting a possible marine larval stage thus reinforcing the hypothesis of a possible connectivity with other populations in the region. More comparisons of migration patterns using otolith microchemistry are required to validate the possible connectivity for the species at the Gulf of Mexico scale or between different periods.…”

“…The technique presented here of calibrating POF from field-collected samples is effective and could be adopted for use in other species with reproductive strategies similar to G. aculeatus. Furthermore, the data demonstrate that POF can be used to estimate interspawning intervals in fishes that spawn large, demersal eggs rather than small, pelagic eggs as has traditionally been done (Hunter & Macewicz, 1985;Brown-Peterson, 2003;Waggy, 2004). Spawning frequency has been successfully determined in marine fishes using both the POF and the OM methods (Hunter et al, 1986;Brown-Peterson, 2003).…”

“…Gasterosteus aculeatus have a short reproductive season in Alaskan lakes (Heins et al , 1999), and the shorter spawning intervals calculated for the earliest portion of the season suggest the majority of reproductive activity in females occurs during this time. A difference in spawning intervals over the course of the reproductive season has not been well documented in any species, although data from estuarine spawning sciaenids such as C. nebulosus and silver perch Bairdiella chyrsoura (Lacépède) suggest a longer period of time between spawns at the end of their extended reproductive seasons (Brown‐Peterson & Warren, 2001; Waggy, 2004).…”

The interspawning interval, or spawning frequency, of wild three-spined stickleback, Gasterosteus aculeatus, was estimated using histological examination of postovulatory follicles (POF). Females in Alaskan lakes appeared to have as much as a 48 h delay between ovulation and ovoposition, yet the POF method could still be used to estimate the interspawning interval. In two Alaskan lakes the interspawning interval was estimated to range from 2.2 to 7.8 days among individual female G. aculeatus. These estimates were consistent with the range (2.5 to 5 days) of previous estimates among individual females from laboratory observations of spawning G. aculeatus, as well as anecdotal accounts of spawning intervals reported from wild populations in Canada (5-10 days). The interspawning interval of females increased during the course of the spawning season in Alaska, showing that the majority of female spawning activity occurred during the earliest portion of the approximate 6-week reproductive season. The increased interspawning interval appears to be related to a previously reported decrease in body condition in reproductive females during the breeding season. Thus, female G. aculeatus may be unable to sustain the initial rate of reproduction as energy stores that support the rapid growth of vitellogenic oocytes are depleted.
