However, knowledge on its yolk absorption, mouth size development, and first food ingestion timing is still lacking up-to-date. This information on the correct feeding of the L. hoevenii larvae are crucial to farmers. The present study hence examined these parameters in the L. hoevenii. The newly hatched L. hoevenii larvae were obtained through natural spawning with the aid of chemicals injection, and sampled consecutively every 2 hours to measure their yolk volumes, mouth height, and to confirm the ingestion time of the first Moina into the larval gut. Also, a starvation experiment was conducted to detect the larval point-of-no-return (PNR). It was found that the yolk sac volume of the newly hatched L. hoevenii larvae was 77.51 μm, and it was completely absorbed at 108 hours after hatching (hAH). The larval mouth has first opened at 36 hAH...

This freshwater bony fish of the family Osteoglossidae inhabits in tannin stained blackwater and forest covered streams including wetland adjacent areas, distributed geographically across Southeast Asia. In Thailand, Surat Thani inland fisheries research and development center under the Department of Fisheries had been successful in breeding these fairly large mouth brooding fish since 1986. The earthen ponds and waters flowing through, 800 to 1,600 meter squares in size and 1 meter of water depth, are commonly practical used for selective breeding and domestication. About 80 captive–bred pairs will be stocked. Adult fish, water insects and some supplementary pellets are daily fed and then courtships together with spawning behavior will be also inspected weekly. Courtship and ...

Data relating to the respondents' characteristics and their productivity were collected using a questionnaire incorporating the Behaviorally Anchored Rating Scale. The samples were drawn from 31 nurses form the emergency room (ER) and 29 nurses from the intensive care unit (ICU) wards of a public hospital in Surabaya, Indonesia, of whom, 52 nurses participated voluntarily and indicated their willingness to respond by signing an informed consent form. The chi-square and Fisher's exact test was used to determine associations between the determinants (demographic characteristics, lifestyle and nutritional status) and productivity and the strength of association was identified by using logistic regression. The results from this study found that gender had borderline significant and duration of work experience had a significant association with nurse productivity. Therefore, gender and duration of working experience are factors which should be taken into consideration when managing human resources working in ERs and ICUs while basic nursing competencies are clearly also important factors in maintaining productivity.

Monthly catch weights in Songkhla Lake were recorded over the period January 2003 to December 2006 inclusive for each of 127 species: 72 were marine vertebrate; 22 freshwater vertebrate; 21 marine invertebrate; 10 diadromous, and 2 catadromous. Linear regression model base on the log-transformed catch weights classified species and months, using these factors as multiplicative determinants based on principal components were performed, enabling assessment of clustering of species. The model has four such components which correspond to predominant seasonal time series patterns, giving an r-squared value of 87.7%. Purely seasonal patterns were identified for the first two components: estuarine and marine vertebrates showed considerable seasonal fluctuations but otherwise appeared to be steady over the four year period. Trends, mainly confined to the most recent year (2006) were identified for the third and fourth components: freshwater and estuarine fish had increasing catch weights, while the catch weights of marine invertebrates decreased. This model can provide practical lake information and reinforces that migratory fish species in tropical shallow lake need to be managed for sustaining their diversities.

Catch weights were first aggregated by species and combination of bi-monthly season of year and catching gear (set bag net, trap, or gill net) and were log-transformed to remove skewness. A regression model containing three species-season/gear components was then used to predict these outcomes. The first component was represented by the most species of estuarine and marine vertebrates as well as some invertebrates and reflected the fact that set bag net was the gear that resulted in the highest catches. The second component mainly represented freshwater fish and some marine invertebrates, and reflected the fact that most of these species were caught by gill nets. The third component focused on the seasonal fluctuations in catch weight. Such models can provide further tools in understanding of fish community structure clustering in fishery landings.
