The oxidation state of traditional fish products was measured by determining the malondialdehyde (MDA) level by HPLC and the results were compared to those given by a spectrophotometric method. The procedure involves oxidation of the products by incubation at 40 degrees C for 3 d. Samples were steam distilled in a Kjeldahl distillation apparatus and the MDA was determined in the aqueous distill...

Diet analysis is an important aspect when investigating the ecology of fish-eating animals and essential for assessing their functional role in food webs across aquatic and terrestrial ecosystems. The identification of fish remains in dietary samples, however, can be time-consuming and unsatisfying using conventional morphological analysis of prey remains. Here, we present a two-step multiplex ...

this study was carried out to determine the effects of immunogen as a prebiotic on growth-related parameters and gut micro-flora in r. kutum fry. a basal diet was formulated using common feed ingredients supplemented with immunogen at 0, 1, 1.5, and 2 g kg-1 leading to four experimental diets.  fish were randomly distributed in 500 l fiberglass tanks (1×1×0.5 m). the experiment lasted for eight ...

Mosquito larvae and their predators or pathogens expected to co-exist in every breeding habitat of mosquito ranging from small temporary sites to large permanent sites. Micro invertebrates are more common, prevalent and numerous than macro invertebrates in aquatic habitats. Micro invertebrates are important as food sources for macro invertebrates and fish (Gilbert and Burns, 1999; Hampton and G...

Biomaterials in nature exhibit delicate structures that are greatly beyond the capability of the current manufacturing techniques. Duplicating these structures and applying them in engineering may help enhance the performance of traditional functional materials and structures. Inspired by gecko's hierarchical micro- and nano-fibrillar structures for adhesion, in this work we fabricated micro-pi...

E-mail address: [email protected]; [email protected] Abstract This article presents the development of an optimized droop controller of microgrid during islanding using artificial fish swarm algorithm (AFSA). This is necessary in order to minimize the frequency deviation that occurs when microgrid switches to stand-alone mode or when there are changes or variation in loads. The optimize...

Background:Breast cancer remains the most common and second lethal cancer in females. HER-2/neu is one of the most important amplified oncogene in breast cancer. The amplification of HER-2 is correlated with decreased survival, metastasis, and early recurrence.  The amplification of HER-2/neu gene and synthesis of th...

In the laboratory, newly hatched fry of Rivulus marmoratus were effective predators on 1st-instar Aedes taeniorhynchus. Adult fish consumed 4th-instar Ae. taeniorhynchus and egg rafts of Culex quinquefasciatus at a rate increasing with standard length of the fish. Predation of Rivulus marmoratus on Ae. taeniorhynchus larvae in the field was documented by observing the passage of larval/pupal re...
