Research in migration route of hatchery released Chinese shrimp(Fenneropenaeus chinensis) in the Bohai Bay using method of SSR marker

This study provides new insights for the hatchery released Chinese shrimp(Fenneropenaeus chinensis), including proportion, dynamic migration route, after they were released into nature for stock enhancement using a new strategy quite different than ever. Chinese shrimp were sampled at 22 survey stations during two investigation voyages acrossing 74 survey stations in the Bohai Sea from July 16 to August 9 in 2015. Am...  (本文共6页) 阅读全文>>

Single or combined effects of dietary arabinoxylan-oligosaccharide and inulin on growth performance,gut microbiota,and immune response in Pacific white shrimp Litopenaeus vannamei

The single and synergistic effects of dietary arabinoxylan-oligosaccharide(AXOS) and inulin at different doses(2,4,and 8 mg/g diet) on survival,growth performance,gut microbiota,and immune response in Pacific white shrimp Litopenaeus vannamei were assessed.Singular application of either inulin or AXOS at doses of 4 mg/g diet showed the most stimulatory effects on the growth rate and gene expression levels of chitinas...  (本文共14页) 阅读全文>>

The carotenoid characteristics of the important wild shrimp Trachysalambria curvirostris(Stimpson,1860) in China

Trachysalambria curvirostris is an economically important shrimp in the coastal waters of the Western Indo-Pacific. However, there is no information about its carotenoid composition and distribution.The carotenoid profiles including concentration, composition, molecular forms(free or esterified) and configuration(geometrical and optical isomers) of raw and dried T. curvirostris(Stimpson, 1860) were qualitatively and ...  (本文共7页) 阅读全文>>

Heterosis and heritability estimates for the survival of the Pacific white shrimp(Litopenaeus vannamei) under the commercial scale ponds

The aim of the present study is to detect the potential of the base population from diallel crosses of eight introduced strains of the Pacific white shrimp(Litopenaeus vannamei) for improving the yield. Heterosis and heritability were estimated for pond survival at commercial farm conditions for the base population that included 207 full-sib families from a nested mating design by artificial insemination. Among all t...  (本文共7页) 阅读全文>>

Prediction of shelled shrimp weight by machine vision

The weight of shelled shrimp is an important parameter for grading process.The weight prediction of shelled shrimp by contour area is not accurate enough because of the ignorance of the shrimp thickness.In this paper,a multivariate prediction model containing area,perimeter,length,and width was established.A new calibration algorithm for extracting length of shelled shrimp was proposed,which contains binary image thi...  (本文共6页) 阅读全文>>
