“…We believe the former group to be more susceptible to secondary transport because of exposure to available offshore horizontal currents induced by the increased wave disturbance. Similar subsurface horizontal movements offshore for brown sole Pleuronectes herensteini larvae has been found during onshore winds, where larval retention was dramatically reduced (Nakata et al 2000).…”

Disturbance in seagrass habitats may cause variation in the structure of fish assemblages and individual taxa. One important form of disturbance is wave action associated with strong winds. Total fish abundance and species richness from seagrass beds at 2 sites in Port Phillip Bay, Australia, were sampled during low and high wave disturbance. During high wave action (> 0.25 m) in seagrass beds, abundance of fish at one site decreased significantly, but species richness was unaffected at both sites. Plankton sampling conducted at the same time as seagrass sampling (directly 300 m offshore from the seagrass sites) found that species richness significantly increased during high wave conditions at both sites. Total fish abundance similarly increased in the plankton during high wave conditions at one site. We conclude that variation in assemblage structure during increased physical disturbance is related to variation in a small number of numerically dominant species within the assemblage. At the individual taxon level, numerically dominant species in the seagrass and plankton showed considerable variation in response to disturbance. In the seagrass assemblage, post-larval King George whiting Sillaginodes punctata (Cuvier and Valenciennes), adult weedfish Heteroclinus perspicillatus (Cuvier and Valenciennes), and pipefish juveniles and adults from the genus Stigmatopora decreased in abundance at either one or both sites during high wave conditions. Conversely, in the plankton, adult pipefish Hypelognathus rostratus (Waite and Hale), juvenile Stigmatopora and larval Gymnapistes marmoratus (Cuvier and Valenciennes) significantly increased in abundance during these same physical conditions. It appears that for some taxa physical disturbance may facilitate secondary planktonic dispersal.

“…Although no clear relationship between mean BL and depth was observed, the largest larvae (.6 mm BL) occurred at the deepest layer at each station in this study. Nakata et al, 2000;Bartsch & Coombs, 2004), due to different current velocities and directions between the upper and lower layers in the study area (Yanagi et al, 1996). below the mixed layer, the WMT of the large larvae habitat would be lower and the WMS and WMC higher than the estimation of this study (Table 3).…”

Distribution, hatch-date, growth, and mortality of larval Benthosema pterotum (Pisces: Myctophidae) in the shelf region of the East China Sea

We examined the distribution, hatch-date, growth, and mortality of larval Benthosema pterotum, a dominant pseudoceanic myctophid in the shelf region of the East China Sea, during early autumn when the main spawning has been predicted. This species is a key species in the food web of this area. Larvae were abundant in the area south of Cheju Island (60-80 m depth), corresponding with the adult habitat. Occurrence of the larvae was restricted to the onshore side of the shelf-break salinity front, indicating that this front acted as a barrier restricting the offshore dispersion of the larvae. In the area where the larvae occurred, a cyclonic eddy is formed, which is considered to limit the dispersal of the larvae, enabling them to recruit into the area of adult habitat. Modes of hatch-date appeared from late August to early September and from mid to late September, suggesting that large-scale spawning events occurred at least twice during the spawning season. Since the modes coincided with the new moon period, B. pterotum is suggested to spawn periodically once a month around the new moon, resulting in efficient mating and fertilization. Mean absolute growth rate (0.26 mm d 21 ) and weight-specific growth rate (18.8% of dry body weight d 21 ) were higher than previously reported values of other subtropical-tropical myctophids, which would be related to the high food availability in the study area. Daily instantaneous mortality coefficient during the first two weeks after hatching was estimated to be 0.28 d 21 (equivalent to 24.7% mortality d 21 ).

“…However, the North Japan Sea stock, which is distributed around the northern mainland of Japan, has considerably decreased [19], and clarification of the mechanism responsible for recruitment fluctuations is essential. To elucidate the mechanism of recruitment fluctuations, the early life history of brown sole has been investigated; spatial distribution of wild larvae [20], feeding of wild larvae [21], settlement size and location of nursery areas in the Japan Sea [22], and modeling of larval transportation [23] have been studied. In addition, rearing experiments have been conducted to improve the quality of hatcheryproduced juveniles [24][25][26][27].…”

Otolith microstructure of brown sole Pseudopleuronectes herzensteini: validation of daily ring formation and the occurrence of microstructure denoting metamorphosis

et al. 2011

Brown sole Pseudopleuronectes herzensteini larvae and juveniles were reared to validate daily otolith ring formation. At 15°C, a check (a distinct ring) formed on the sagittae and lapilli at 6 days after hatching, and clear increments regularly formed outside the check. For both otoliths, the relationship between the number of days after hatching and number of increments was linear, and the slope of the line was approximately 1; therefore, daily formation was validated. At 12°C, the check formed on the lapillus 8 days after hatching. Accessory primordia (AP) began forming on the sagittae of metamorphosing larvae, and the shape of the sagittae became complicated. AP were not formed on the lapillus; concentric rings were formed throughout larval and juvenile stages. Wide and obscure increments formed on the lapilli during metamorphosis (metamorphosing zone, MZ). Based on MZ, concentric rings that have formed on the lapilli of juveniles can be separated into larval and juvenile rings. The morphs of large juveniles' lapilli were bilaterally asymmetric, and the blind-side lapilli were most suitable for otolith microstructure analysis. This study provides fundamental information for otolith microstructure analysis in wild brown sole.
