Age and Growth of Bluegills, Lepomis macrochirus Ra:finesque, from Selected Central Iowa Farm Ponds
Population estimates were made on ~ve .farm ponds in central Iowa during 1965. Age and growth determmat10ns were ma.de from scales of 638 bluegills collected from these ponds. Bluegills standing crops averaged 248 pounds per acre, ranging from 201 to 3 21 pounds per acre. Growth rates of bluegms from the balan~ed ponds were average when compared with growth rates of bluegills from other Iowa la...
متن کاملVertical banding evoked by electrical stimulation of the brain in anaesthetized green sunfish, Lepomis cyanellus, and bluegills, Lepomis macrochirus.
A pattern of dark vertical bands is a characteristic agonistic display in the green sunfish, Lepomis cyanellus and the bluegill, L. macrochirus. The rapidity with which the display can appear and disappear indicates that it is neurally controlled. Electrical stimulation of the brain was carried out in anaesthetized green sunfish and bluegills to map those regions from which this colour change c...
متن کاملFirst record of the fish pathogen Flavobacterium columnare genomovar II from bluegill, Lepomis macrochirus (Rafinesque), with observations on associated lesions.
Flavobacterium columnare is the causative agent of ‘columnaris disease’ (Davis 1922), a disease that kills or debilitates a wide ecological and phylogenetic spectrum of temperate and tropical freshwater fish (Bernardet 1989; Bernardet & Grimont 1989; Bernardet et al. 1996; Olivares-Fuster et al. 2007; Bullard, McElwain & Arias 2011). It is regarded as a predominant pathogen of fish maintained i...
متن کاملBiodiversity data mining from Argus-eyed citizens: the first illegal introduction record of Lepomis macrochirus macrochirus Rafinesque, 1819 in Japan based on Twitter information
An apparent illegal introduction of Lepomis macrochirus macrochirus from Yokohama City, Kanagawa Prefecture, Japan, is reported based on a juvenile specimen and a photograph of two adults collected on 14 June 2015 and deposited in the Kangawa Prefectural Museum of Natural History. The specimens and photographs were initially reported on the internet-based social networking site, Twitter. Two sp...
متن کاملTrade-offs between performance and variability in the escape responses of bluegill sunfish (Lepomis macrochirus)
Successful predator evasion is essential to the fitness of many animals. Variation in escape behaviour may be adaptive as it reduces predictability, enhancing escape success. High escape velocities and accelerations also increase escape success, but biomechanical factors likely constrain the behavioural range over which performance can be maximized. There may therefore be a trade-off between va...
