food anticipatory activity (faa) was assessed in rainbow trout ( oncorhynchus mykiss ) in two small raceways using demand-feeding (t2) and hand-feeding (t2). the fish of both raceways were subjected to restricted feeding (rf) at two times in two places and the fish distribution and/or trigger actuation, total agonistic behaviour between fish, and swimming speed were measured. food anticipatory ...

This study was performed to assess growth rate, feed efficiency, and N and P loss of sea bass Ž . initial body weight 3.5 g , held in 500-l tanks under ambient temperature and natural light, and fed according to the following methods: by automatic feeders that released feed continually in Ž . daylight according to feed manufacturers’ recommendations AF100% ; half of the above continuŽ . Ž . all...

The capability of turbots to use self-feeders was studied using 3 groups of 100 juveniles. Feeding activity reached a plateau after 20 days. Almost al1 feeding activity was observed during the photophase, and the acrophase was associated with dawn. The proportion of nocturnal demands was the highest in the replicate with the lowest feed efficiency, suggesting that feed waste was mainly occurnng...

Derivation of pluripotent stem cells (iPSCs) induced from somatic cell types and the subsequent genetic modifications of disease-specific or patient-specific iPSCs are crucial steps in their applications for disease modeling as well as future cell and gene therapies. Conventional procedures of these processes require co-culture with primary mouse embryonic fibroblasts (MEFs) to support self-ren...

Optimal placement of scattered generator sources in the main and secondary feeders of radial grid reduces energy losses, releases the capacity of existing feeders and improves the existing voltage profile. In this project determine the location and suitable for the production of production resources S cattered in radial feeders of unbalanced distribution networks, a new formulation solution is ...

Pine siskins (Carduelis pinus) frequently forage at known high quality food supplies such as backyard feeders. In this field study, pine siskins visited backyard feeders of differing colour and spatial position. The three feeders contained varying amounts of food in a ratio of 3:2:1. The birds quickly distributed their visits in this ratio to the three feeders. During unbaited tests, two feeder...
