Manufactured in Japan

The Gold Standard of Aquaculture. Unlike standard cooked feeds, Otohime utilizes a proprietary 12‑stage low‑temperature extrusion process. This critical difference prevents the denaturing of vital enzymes, amino acids, and complex marine lipids [3]. Supported by an uncompromising recipe unchanged for over two decades, it utilizes incredibly high-value ingredients to deliver unparalleled survival and growth rates.

Operational Efficiency

Redefining Hatchery Economics

Otohime isn't just a feed; it is an operational upgrade. By utilizing the highest quality marine proteins available [3], it fundamentally alters the timeline and cost structure of larval rearing.

Live Feed Replacement

Significantly reduces or entirely cuts out the need for Artemia and Rotifers. By transitioning larvae off live feeds earlier, you eliminate the exorbitant labor, infrastructure, and nutritional variance costs associated with live feed cultivation.

Accelerated Weaning

The intense attractability of premium Krill meal [3] gets fish onto pellets faster. Faster weaning translates directly to faster, more aggressive growth curves in the critical early stages of development.

Eliminates Size Variances

Because the micron sizes are precisely sieved (not just averaged), every larva gets uniform nutrition. This eliminates batch size variances and cannibalism, getting your entire cohort up to stocking size much faster.

Low-Temp Processing

Standard high-heat extrusion destroys nutritional profiles. Otohime's low-temperature manufacturing [3] preserves the delicate β-glucans, DHA, and phospholipids required for absolute peak vitality.

Data-Driven Results

The Scientific Consensus

Note: It is widely documented across global commercial aquaculture literature that Otohime consistently outperforms alternative diets. Below is a summary of its established scientific track record:

The Ultimate Control Diet

In peer-reviewed microdiet formulation studies across marine finfish species (including Seabream, Asian Seabass, and Clownfish), Otohime is universally selected as the benchmark Control Diet. It is chosen because it reliably produces the highest baseline survival and growth curves, often outperforming the experimental diets being tested.

Artemia Withdrawal Studies

Extensive co-feeding trials demonstrate that introducing Otohime A and B-series diets early allows for the rapid withdrawal of Artemia nauplii. These studies prove that early transition to Otohime maintains or exceeds the survival rates of prolonged live-feeding, while drastically reducing operational overhead.
