The Troutlodge advantage
All female eggs
Troutlodge is the world's leading supplier of eyed rainbow trout eggs. We specialise in the production of all-female and triploid (sterile) eggs. All-female eggs are preferred by commercial trout farmers throughout the world. Troutlodge proudly offers all-female Rainbow trout eggs as its standard product, meaning you do not pay a premium for these superior eggs. Maximize your farm's potential through these significant benefits:
- Firmer, more palatable flesh.
- Better feed conversion.
- Better, healthier fish due to fewer males.
- Fewer unmarketable, precocious males at dress-out time.
- Excellent commercial presentation of trout at any time of year.
Triploid trout are also known as 3N or sterile trout. Some of the many benefits of triploid eggs include:
- Better flesh quality compared to diploids
- Better growth to large sizes as all energy is transferred to growth rather than reproduction
- Comparable growth to diploid populations early in the life cycle
- More efficient and productive use of hatchery facilities by removal of unnecessary reproducing fish
- Fish are suitable for release without genetic impact, as they cannot breed with native populations
These benefits help make triploid eggs the perfect solution for farmers needing a sterile salmonid for the following situations:
- Growth past the normal period of reproduction
- Production of "trophy"-sized fish for recreational purposes
- Prevention of reproduction in released or escaped fish
Troutlodge has been a pioneer in the development of triploid technology and processes for the salmonid industry. Thanks to this extensive experience, Troutlodge achieves +99% induction rates in the triploid process. All triploid eggs sold by Troutlodge are all-female.

Winter and Fall Strain rainbow trout (Steelhead)
Availability: mid October - mid April
Troutlodge's "Silver Steelhead" trout are specially bred to have a distinctive silver color and excellent growth in both seawater and freshwater, making them ideal for use in net-pen operations. Winter and Fall steelhead are produced by two distinct strains of trout and both are subject to our comprehensive Genetic Selection Program. These eggs are available from mid-October to mid April.
Availability: late October - April
Troutlodge Manx strain rainbow eggs are available and offered to customers between October and April. We are in the process of transferring our US strain genetics to the Isle of Man facilities, and presently have a mix of both lines. The Manx line is robust but grows a little slower, and as such we offer these at a discounted rate. The Isle of Man’s fish health status is exceptional, so for high quality, high health status eggs produced in Europe please use the button below for a more detailed inquiry and price quote.
