Rainbow trout have highly variable colouration. Rainbow trout that live in lakes have a very silvery appearance, usually with a dark olive-green colour on the back. Occasionally the back is a deep steely blue, mostly in Rainbow trout that live well offshore in deep lakes or in small fish that have not yet spawned. JSAFWA Diet Composition of Wild Brown Trout and Stocked Rainbow Trout in a Coldwater Tailwater Fishery in North Georgia Patrick M. O’Rouke, Georgia Department of Natural Resources, Dawsonville Highway, Gainesville, GA Abstract: The Lanier Tailwater section of the Chattahoochee River, Georgia, below Buford Dam has populations of wild brown trout .
Ecology: Potamopyrgus antipodarum is a nocturnal grazer, feeding on plant and animal detritus, epiphytic and periphytic algae, sediments and diatoms (Broekhuizen et al. , James et al. , Kelly and Hawes , Parkyn et al. , Zaranko et al. ). The snail tolerates siltation, thrives in disturbed watersheds, and benefits from high nutrient flows . % of rainbow trout diet, despite all endemic Megalagrion species being commonly found. Five of the 80 (6% frequency of occurrence) rainbow trout examined during this study contained immature Megalagrion in their guts, with most from Waiÿalae (n = 4) and one native damselfly from a trout collected in Koaiÿe Stream.

We evaluated the potential for feeding morphology to affect prey selection by rainbow trout using a combination of laboratory feeding experiments and field observations in Flaming Gorge Reservoir.
Zooplankton grazing is widely discussed in the literature [reviews see (Gulati, ; Sterner, )]. The PEG model (Sommer et al., ) demonstrates the potential influence of zooplankton grazing on phytoplankton structure and density along the time course of seasonal succession in by: Vol.

Rainbow trout are known to be size-selective predators on zooplankton and to preferentially feed on large-bodied Daphnia (Geist et al.

Cornel and F.G. Whoriskey Department of Renewable Resources, Macdonald College of McGill University, Cited by: In Flaming Gorge Reservoir, stocked rainbow trout would have to utilize the zooplankton food base for at least some time period after stocking, as there are likely few other small-size food items.

This study intended to determine the effect of rainbow trout culture on the quality of. In spring zooplankton removed daily 27% of the total B&pinf; and 29% of PP by grazing while in summer these values rarely exceeded 5%.
Zooplankton grazing was responsible for the decrease of `edible' (Cited by: The diel grazing activity of zooplankton was measured at a single study site in a temperate fjord, Dabob Bay, Washington, USA at several periods during spring, summer and fall of – Pheopigments were used as an indicator of herbivorous zooplankton activity.
The downward vertical flux of pheopigment-containing fecal pellets was measured with sediment Cited by: the maximum longevity for rainbow trout was 9 years, for cut-throat trout, 11 years, and for brook trout, 13 years (Donald et al.
; Donald and Alger ). Five of the 13 lakes (Colfair, Cutt, Dragon, Golden, and Little Honeymoon) were stocked infrequently, and their zooplankton assemblages may not have been measurably. (DWSC) of the San Joaquin River (SJR) estuary.
Zooplankton grazing is one of the important mechanisms that influence the fate and spatial distribution of algae, and therefore, may contribute to DO deficits that adversely impact aquatic habitat and salmonid migration in the SJR estuary.

Ninety-seven percent of all zooplankton observed in the diets of rainbow trout collected in the reservoir were larger than the interraker spacing, while only 29% of the zooplankton found in the environment were larger than the interraker spacing. Over the size range of rainbow trout evaluated here ( mm), interraker spacing increased moderately with increasing fish length; however, the size of zooplankton found in the diet.

Rainbow trout have replaced Lahontan cutthroat trout in areas where the cutthroat is native and Rainbow Trout have been introduced (McAffee b). Introduced rainbow trout, and other trout species, were likely responsible for the near-extinction of Lahontan cutthroat in Lake Tahoe in the s (McAffee b).

SPAWN TIMING: Cutthroat trout and most rainbow trout spawn in spring as water temperatures rise, starting at about 5 degrees Celsius (C). Brown, brook, and lake trout all spawn in the fall as water temperatures drop.
Some trout in the Firehole River spawn in winter months, a shift caused by the thermally influenced waters.Square Lake (Washington County, MN) has historically been among the clearest lakes in the Minneapolis-St.
Paul metropolitan area, but it has experienced declining water clarity due to increased levels of algal biomass over the past several decades. Predation by rainbow trout (annually stocked since the early s by the Minnesota Department of Natural Resources .catchable-sized rainbow trout are stocked in over water bodies across Idaho annually, but there remains some uncertainty regarding the performance of triploid rainbow trout relative to their diploid (2n) counterparts.
