“…Multiple-spawning seasons are also common in tropical fishes [21,22]. This reproductive strategy has been suggested to reduce the negative impacts of environmental variation on reproductive success [23,24]. N. taihuensis is one of the most widely introduced fish in China.…”

Neosalanx taihuensis were sampled from the Tian-e-zhou Oxbow from March 2006 through November 2007. Two separate spawning seasons were identified based on the annual reproductive cycles of the females, designated as the autumn-spawning season and the spring-spawning season. Lifespan of the offspring of the spring-spawning fish was 1 year, with them dying after the subsequent spring spawning. Autumn-spawned females seem to be the offspring of the spring-spawning fish, based on monthly changes in the length-frequency distributions. Springmature females had higher absolute fecundity, gonadosomatic index, and relative condition factor in 2007 than in 2006. Relative condition factor of the immature female offspring of spring-spawning fish was higher in 2007 than in 2006, portending a further increase in reproductive investment during the spring spawning of 2008. The increasing reproductive investment suggests that the population of N. taihuensis in the Tian-e-zhou Oxbow may be recovering from its recent decline.

“…By the age at flexion, however the majority of surviving larvae from the distinct spawning grounds are relatively well mixed. This high degree of mixing is reflected in the molecular structure of adult populations around Tasmania, which are a single panmictic stock (Tracey et al. , 2007a).…”

The effect of dispersal and temperature on the early life history of a temperate marine fish

Understanding the mechanisms that influence the successful recruitment of marine species is one of the great challenges in marine science, particularly for species that undergo a protracted larval phase. Here we apply a bio‐physical individual‐based model (IBM) which couples data from a high‐resolution oceanographic model with temperature‐related survival characteristics for the early life stage of a temperate marine fish. The IBM was run retrospectively for the years 1993–2007 with spawning locations occurring around Tasmania, Australia. Meso‐scale oceanographic features led to individuals spawned on the west coast, and to a lesser extent the south coast, being washed ashore prior to achieving a competent size to actively influence their migratory paths. Individuals spawned on the east coast had significantly higher survival rates. Temperature‐induced mortality was relatively consistent across years. This indicates that the dispersal envelopes, of pre‐flexion larvae, across all years are predominately within the thermal niche of this species. To further understand the effect of temperature on survival we integrated global climate model warming scenarios into the model. The results indicated that around the year 2050 the predicted warming would have a minor positive effect on the survival of individuals but by 2100 the pejus temperature will frequently be exceeded leading to a significant decline in survival, particularly towards the northern end of the dispersal range.

“…Results of this study provide fundamental information for understanding the life history of N. taihuensis. Multiple seasonal spawning stocks within fish populations has been suggested to be a reproductive strategy to reduce the negative impacts of environmental variation on reproductive success [29,30]. Our previous study on another N. taihuensis population in the middle reach of the Yangtze River demonstrated that the proportion of autumn-spawning females increased as population abundance recovered from a low level [9].…”

Otolith microstructure was used to distinguish specimens of Neosalanx taihuensis born in spring and autumn. Increment width during the early life stage was significantly narrower for spring-born than autumn-born juveniles, and the frequency distributions of the width of the first 5 increments were distinctive and diagnostic. Otolith growth trajectories and frequency distribution of the first 5 increments of spring-spawning adults displayed similar patterns to spring-born juveniles. Otolith growth trajectories of autumn-spawning adults were intermediate between those of spring-and autumn-born juveniles, and the frequency distribution of the width of the first 5 increments showed two modes, one similar to spring-born juveniles and the other similar to autumn-born juveniles. Populations of N. taihuensis have previously been shown to be dominated by spring-spawning fish. Thus, the putative life history of N. taihuensis can be summarized as: (1) a small part of the spring-born fish mature and spawn in autumn of the year of their birth, (2) the majority of the spring-born cohort matures and spawns in spring of the next year, and (3) offspring of the autumn-born fish mature and spawn in autumn of the following year. This stockstructure information should be considered in fisheries management for this species.
