Studied Benefits in Aquaculture
Studies have evaluated its use in fish and shrimp feed
Weight Gain in Tilapia
Natural clinoptilolite in Nile tilapia feed, from 1% to 5%, increased weight gain (Abbas et al., 2021; Al Amir & Ali, 2022)
Less Ammonia in the Water
Tilapia fed a diet containing clinoptilolite had less total ammonia in the tank water (Abbas et al., 2021; Al Amir & Ali, 2022)
Shrimp Feed Conversion
With 5% clinoptilolite-type zeolite in the feed, Pacific white shrimp had better feed conversion, with no difference in survival (Kim et al., 2025)
Applications in Aquaculture
Solutions for fish and shrimp nutrition
Feed Additive - Tilapia
Inclusion in tilapia feed. Studies tested 1% to 5% natural clinoptilolite in the feed and observed higher weight gain (Abbas et al., 2021); in a 1% to 3% trial, the best result was at 3% (Al Amir & Ali, 2022).
Feed Additive - Catfish and Shrimp
Inclusion in catfish and shrimp feed. We found no studies with the powder in catfish feed. In Pacific white shrimp, 5% clinoptilolite-type zeolite in the feed (dose tested in the study) improved feed conversion, with no difference in survival (Kim et al., 2025); in river shrimp, 8% reduced survival (Senmache et al., 2020).
