The quantitative distribution and biological characteristics of Solenocera alticarinata in the Northeast Fujian outer-sea

According to the shrimp survey data of four seasonal months in the Northeast Fujian outer-sea (26°00′~28°00′N, 120°00′~125°30′E), this paper studied and analyzed the quantitative distribution and biological characteristics of Solenocera alticarinata. The results showed that the average density of its resource in May, August, November and February were 34.7, 13.8, 4.55 and 2.89 kg·km^-2, respectively. The quantitative distribution was obvious different from the seasons with May and August being more and November and February being less.The area of high biomass density occurs in the northeast waters of the survey sea and the highest occurs in the waters at depth of 80 to 100 m (27°00′~28°00′N, 122°30′~124°30′E). The body length varied between 41 and 129 mm, the dominant were between 80 to 100 mm occupying 44.7%. The female was obviously larger than the male with the sex ratio 1:0.66, the average body weight was 12.0 and 8.3 g, respectively. There was no obvious difference for feeding intensity from the seasons or between different sex.
