“…primarily when it was cyclic (Galloway & Kilambi 1988), with Diana (1984) revealing that growth increments were increased when fish were exposed to cyclic warm (29°C) and cool (15°C) temperatures when compared with those achieved during constant warm temperatures. It is also in contrast to Barwick & Lorenzen (1984) who reported the increased growth of M. salmoides in an impounded reservoir as being associated only with increased prey size and abundance and not elevated temperatures.…”

Britton JR, Harper DM, Oyugi DO. Is the fast growth of an equatorial Micropterus salmoides population explained by high water temperature? Ecology of Freshwater Fish 2010: 19: 228–238. © 2010 John Wiley & Sons A/S Abstract – Marginal increment analysis of scales collected from the introduced Micropterus salmoides population of Lake Naivasha, Kenya revealed the formation of an annual growth check, validating their use to age individual fish. Subsequent analysis of scales from 372 fish collected between 2002 and 2009 revealed individuals were very fast growing compared with native populations in North America and other introduced populations in Europe, South America, Africa and Asia. This was likely to be as a result of the water temperatures in Lake Naivasha exceeding 20 °C throughout the year. This was corroborated by a meta‐analysis of the growth parameters asymptotic length L∞ and growth coefficient K from across their geographical range that revealed variance was explained by differences in mean annual air temperatures. At a break point of approximately 10 °C, there was a shift to reduced L∞ and increased K, suggesting a temperature driven trade‐off between growth rate and ultimate length. When adjusted for temperature and weighted for sample size, there were significant differences between the growth parameters of the North American and introduced populations, suggesting that other abiotic and biotic variables were also important determinants of the growth of individuals between the two ranges.

“…Austrolebias spp. are known to be sensitive to higher water temperatures (Errea & Danulat, 2001;Fonseca et al, 2013;Polačik & Podrabsky, 2015). Data from the current study indicate that annual fishes may disappear from the pools before they dry.…”

“…The other five pools were only located during the second sampling date, but it is possible that annual fishes hatched in June. It has been suggested for African annual fishes from southern Mozambique and for Austrolebias viarius (Vaz-Ferreira, Sierra de Soriano & Scaglia de Paulete 1965) from eastern Uruguay that their hatching may not be coincident with the initial habitat inundation, but rather with strong precipitation associated with major cyclones in the second part of the rainy season (Errea & Danulat, 2001;Watters, 2009;Reichard et al, 2015). In contrast to Mozambican Nothobranchius, there appears to be low hatching synchrony across a relatively small spatial scale of the range of annual killifishes.…”

Seven ephemeral pools on the coastal plain of southern Brazil were found to be inhabited by three annual and 22 non-annual fish species. Two common annual species (Austrolebias minuano and Cynopoecilus fulgens) exhibited clear seasonal dynamics, with the appearance of young fishes in the austral autumn (May to June) and a decline in abundance over the seasonal cycle. The third annual species, Austrolebias wolterstorffii, was rare. No seasonal dynamics were observed in non-annual fishes. The relative abundance of non-annual fishes compared with annual fishes increased over the seasonal cycle, but they coexisted widely. The size structure of annual fishes suggested the presence of a single age cohort in most pools though a second age cohort was registered in one pool in August, coinciding with a large flooding. Strong sexual dimorphism in body size was found in C. fulgens throughout the seasonal cycle, while no sexual dimorphism in body size was found in A. minuano. Female-biased sex ratios were recorded in both common annual fish species in the last three sampling dates (in spring), but not during the first two sampling dates (in winter). The natural lifespan of annual fishes was <8 months. Annual fishes disappeared before habitat desiccation in half of the pools, while non-annual fishes were still present.

“…In Lake Monona, WS (0.16 MW/ha) and Keowee Reservoir, SC (0.35 MW/ha) growth rates of bluegill and yellow bass, Morone mississipiensis, and bluegill and largemouth bass, respectively, were apparently dependent on abundance and size of prey and on size-dependent movements, rather than elevated water temperatures (Neil1 & Magnuson, 1974;Barwick & Lorenzen, 1984). Thermal effluent may affect growth indirectly by influencing the abundance of prey species (Janssen & Giesy, 1984), such as at Par Pond, SC (MW/ha of power plant not reported).…”

Analysis of largemouth bass scales, including those from 48 tagged and recaptured fish, revealed that many scales had more ' annuli ' than possible for the age of Flint Creek Cooling Reservoir.The mark-recapture data indicated the formation of one supernumerary annulus per year for most bass. Time of formation of true and supernumerary annuli and the causative factors are discussed.Growth of bass from this reservoir greatly exceeded that reported for thermally unaltered reservoirs of Northwest Arkansas, due to the existence of a nearly year-round growing season, a result of thermal enrichment. The relationship between the ratio of electric power output to reservoir surface area and growth offish was evaluated with reference to published data on cooling reservoirs.
