# Cassiopea xamachana polyp feeding under husbandry conditions

## TL;DR

This study improves care for upside-down jellyfish polyps by finding optimal feeding and light conditions for their survival and reproduction.

## Contribution

The study identifies effective husbandry conditions for Cassiopea xamachana polyps under controlled settings.

## Key findings

- Polyps show better survival in a day/night light cycle.
- Additional food beyond Artemia nauplii boosts reproduction.
- Aposymbiotic and symbiotic polyps benefit similarly from improved feeding.

## Abstract

Research on the upside-down jellyfish
Cassiopea xamachana
has increased in the past few decades, hence the need for more efficient husbandry protocols. We tested the effect of weekly feeding frequencies, light cycles, and nutrient supplements on symbiotic and aposymbiotic polyp asexual reproduction and mortality.
C. xamachana
polyps have better survivorship and reproduction when kept in a day/night cycle and given additional food beyond
Artemia
nauplii.
