Certified Salmon & Trout Ova Sourcing Hub

Atlantic salmon (Salmo salar), Coho salmon (Oncorhynchus kisutch) and rainbow trout (Oncorhynchus mykiss) as certified fertilized eyed ova, including diploid, triploid and all-female strains depending on species. Supply runs through a diversified network of certified hatcheries rather than a single origin, which is what keeps a season workable when one source is disrupted.

Atlantic salmon eggs require approximately 480–520 Accumulated Thermal Units (ATUs or degree-days) to hatch, Coho salmon require 450–500 ATUs, and Rainbow trout require 310–330 ATUs. Because eggs ship at the resilient eyed stage (typically 220–250 ATUs for Atlantic salmon), they arrive with approximately 240–280 ATUs remaining to hatch. In a standard incubation system running at 7–8 °C, hatching commences within 30 to 38 days post-arrival. ATUs are calculated by multiplying the water temperature in °C by incubation days.View salmonid ova solutions

A mature female Atlantic salmon (Salmo salar) produces approximately 1,200 to 1,800 eggs per kilogram of body weight, yielding between 8,000 and 18,000 eggs per broodstock hen depending on age and weight class. Egg diameter averages 5.5 to 6.5 mm with individual egg weights between 115 and 145 mg. Broodstock nutrition, water temperature and photoperiod manipulation ensure uniform egg sizing and lipid yolk reserves prior to stripping.

Ova are sourced from certified, health-screened hatcheries and ship with the health certification their origin authority issues, covering the pathogens listed for the species and destination. Screening is done at the source hatchery under its own veterinary supervision — we supply the certificates with the consignment, we do not issue them ourselves.

As eyed ova in insulated shipping boxes held at chilled temperature, moved by air freight and monitored with data loggers. Eyeing is the point at which the embryo tolerates handling, which is why ova are shipped at that stage and not earlier; on arrival they go straight to the incubator with minimal thermal shock.Salmonid ova solutions

Yes. Ova ship with handling and incubation guidance covering tempering on arrival, incubation temperature and the degree-day expectation to hatch for the species and batch. Our Japanese and Korean hatchery clients received exactly this support alongside the consignments, and it is part of the supply, not a paid extra.

Live feed, microalgae and stocked feed ingredients usually ship within a week of order confirmation. Fresh Mediterranean seafood is harvested to order and leaves within days. Salmonid ova are the exception: they ship against the hatchery's stripping and eyeing calendar, so volumes are best reserved months ahead of the incubation date you are planning for.

For salmonid ova, yes and unavoidably so — supply follows the broodstock stripping and eyeing calendar, which is why ova are reserved ahead rather than ordered off the shelf. Mediterranean seafood is farmed year-round with size grades shifting through the season. Live feed, microalgae and feed ingredients carry no meaningful seasonality.
