Abstract

Abstract

Paracalanus sp., which has been identified as Paracalanus parvus by previous reports in the northern part of China seas, is a very common small copepod in Laizhou Bay, Bohai Sea. The species is characterized ecologically by a high level of secondary productivity and a suitable food resource for early larvae of fishes in the bay. To explore the population dynamic in Laizhou Bay, copepodites and adult data of Paracalanus sp. were collected and analyzed from 147 samples over the annual surveys from May 2011 to April 2012 (excluding December 2011 and January and February 2012, because of the presence of sea ice). The results showed Paracalanus sp. occurred continuously in the plankton throughout the year, with an enormous peak in August. Its stage-specific population structure and body size fluctuated greatly during the study period. During the surveyed seasons, copepodites stages CⅢ, CⅣ and CⅤ contributed most percentages in total population abundance except that from April to June when the adults became dominant. Of the copepodite stages, CⅣ and CⅤ accounted for the largest proportion of the total population abundance from October to March. In the adult, pronounced dominance of females over males was found throughout the year. The female to male ratios ranged from 1.46 to 9.62, with the lowest value in March and April and highest in October and November. The body size of Paracalanus sp. changed seasonally, being the largest in April or May, and the smallest in August. Mean body size of each developmental stage was inversely related to temperature at the time of sampling by regression statistic. The biomass of Paracalanus sp. showed marked seasonal variations largely in parallel with numerical abundance. Its monthly mean value was 2.69 mg/m³. The species production rate was estimated with 0.74 mg/(m³·d) based on the reported experienced equation. From above results, the annual population dynamic of Paracalanus sp. could be divided into three main phases, starting breeding phase from April to June, rapid population growth phase from July to August, and relative population growth stagnation phase just after September.
- Paracalanus sp.,
- stages-specific abundance,
- prosome length,
- seasonal variation,
- Laizhou Bay
