Growth rates of rainbow trout in farms are much higher those that of wild fish, but growth rates in farms also vary with water temperature. In constant 15 °C freshwater, farmed rainbow trout reach 800–1 000 g in weight 12 months after eggs hatch (Figure 5).

2021年11月6日 · On average, an adult trout is between 1-2kg and can live for about 8 years! This depends on the variety. Rainbow trout are larger, around 2-3 kilograms. Despite the average weight, many trouts can reach up to 50 or more Kilos!! Trouts can survive in the broad temperature range of 0c to 27c.

2024年12月18日 · Rainbow trout are known for their fast growth rate, which can be influenced by factors such as feeding habits, water temperature, water quality, and genetics. Understanding the different growth stages of rainbow trout and the conditions they require is …

The aim of this study was to determine the growth performance and survival of rainbow trout (Oncorhynchus mykiss) in floating cages in the south of the Caspian Sea.

Adult freshwater stream rainbow trout average between 0.5 and 2.5 kilograms (1 and 5 lb), while lake-dwelling and anadromous forms may reach 9 kg (20 lb). Coloration varies widely based on subspecies, forms, and habitat.

Results showed that it is possible to achieve high survival (96.6 1.7%) with reasonable growth rate (0.8 0 g.fish-1) and productivity (89 27 kg.cage-1) with fair condition factor (1.2 0.1) when stocked 10-20 fish.m-3.

This presentation is intended for the family-owned and -operated trout farm producing 15-50 tons (30,000-100,000 lbs.) per year. The impetus for my writing this text comes from hearing genuine concerns about rainbow trout in the marketplace. Chefs, restaurateurs, and retailers have stated quite clearly and repeatedly that they

growing trout are 55F to 65o F. At this temperature range feeding rates should be at maximum lev-els (1.5 to 6.0+ percent of body weight per day). The best way to determine the correct amount and size of feed for trout production is to use a published feeding chart, usually Table 1. Examples of feeding rates for rainbow trout.
