Consensus Decision Making by Fish
Decisions reached through consensus are often more accurate, because they efficiently utilize the diverse information possessed by group members [1-3]. A trust in consensus decision making underlies many of our democratic political and judicial institutions [4], as well as the design of web tools such as Google, Wikipedia, and prediction markets [5, 6]. In theory, consensus for the option favor...
متن کاملMaking male gametes in culture.
M aking sperm in a culture dish has been a long-term goal of reproductive biologists. In 2010, a group of investigators from Yokohama, Japan, reinvestigated an organ culture system that was originally used for testicular tissue in the 1960s (1–3). By using better molecular markers, they were able to demonstrate that some cells in this culture system underwent complete meiosis to form round sper...
متن کاملAchieving Natural Coloration in Fish under Culture
Fish that are colored in nature often acquire faded coloration under intensive culture conditions. Experiments adding top-coated algae to the diets of ornamental fish have resulted in color enhancement. Freshwater red velvet swordtails Xiphophorus helleri, rainbowfish Pseudomugil furcatus, and topaz cichlids Cichlasoma myrnae became significantly more intensely colored when fed a diet containin...
متن کاملPathology of Myxosporea in marine fish culture
A revlew of the pathogenic impact of Myxosporea in marine fish culture is presented. At least 11 species of Bivalvulida and 7 species of Multi\~alvulida have been described in marine or brackish fish kept in different culture systems. The pathological importance of these myxosporoses is discussed, and their potential importance with the growth of culture facilities is stressed.
متن کاملQuorum Decision-Making in Foraging Fish Shoals
Quorum responses provide a means for group-living animals to integrate and filter disparate social information to produce accurate and coherent group decisions. A quorum response may be defined as a steep increase in the probability of group members performing a given behaviour once a threshold minimum number of their group mates already performing that behaviour is exceeded. In a previous stud...
