Application of a fat staging technique to examine temporal and spatial variability in lipid content of southern Benguela sardine Sardinops sagax

A recently developed technique to estimate the lipid content of pelagic fish, using macroscopic visual assessment of their mesenteric fat, was applied to samples of southern Benguela sardine Sardinops sagax collected from commercial catches over the period 1996–2004. The data were analysed using general linear modelling, and temporal and spatial variably in lipid content was examined and compared with that of condition factor derived from length/mass relationships. Lipid content showed a clear seasonal cycle, being highest in May and lowest in August. This pattern was comparable with seasonal cycles in condition factor, although lipid content peaked 1–5 months later than did condition factor. A strong spatial effect was apparent in model results, with both lipid content and condition factor being highest in sardine from the South-East Coast. The correspondence in results from the fat staging technique, and those derived using condition-factor data for longer time-series, validate the new technique, and the higher level of resolution of the former compared with the latter argue for broader application of this technique.     

一个嵌入式文件系统CEFS的设计与实现

详细介绍了一个嵌入式文件系统CEFS的设计与实现。该文件系统是基于实时嵌入式操作系统CR-TOSII内核,采用IMFS和FAT位图文件系统格式实现的。CEFS文件系统分为3个实现层次,自底向上分别是：设备驱动程序、高速缓存管理和文件系统核,并向用户提供了基于POSIX的文件系统API接口。它的最大优点就是文件系统的开放式体系结构。     

Major endoparasites of the Cape hakes Merluccius capensis and M. paradoxus,with brief notes on some conspicuous ectoparasites

The major endoparasites of Cape hake are larvae of the nematode Anisakis sp. and the trypanorhynch cestode Hepatoxvlon trichiuri. Incidence and degree of infestation by Anisakis sp. were high and similar in both species, and the parasite is one of the most important natural enemies of hake. H. trichiuri was not as common or apparently pathologically destructive as Anisakis and infected Merluccius capensis more frequently and intensively than M. paradoxus. Other parasites of Cape hake, both internal and external, are listed.
