Here, we present a protocol to demonstrate the generation of ice when water is introduced to a cold bath of brine, as a secondary refrigerant, at a range of temperatures well below the freezing point of water. It can be used as an alternative way of producing ice for industry.

This study presents a gelatin-based feeding method that enables precise, non-invasive, body mass–based oral drug delivery in adult zebrafish. The protocol demonstrates reliable feed acceptance and, as a proof-of-principle, successful delivery of MK-801, which resulted in the expected behavioral effects.

Zebrafish Maintenance and Husbandry

The zebrafish (Danio rerio) is a powerful vertebrate model system for studying development, modeling disease, and screening for novel therapeutics. Due to their small size, large numbers of zebrafish can be housed in the laboratory at low cost. Although zebrafish are relatively easy to maintain, special consideration must be given to both diet and water quality to in order to optimize fish health and reproductive success. This video will provide an overview of zebrafish husbandry and...
FAQs
Hydration reactivates metabolism in the dormant cyst, allowing the embryo to resume growth. As development proceeds, internal changes increase pressure and lead to rupture of the shell, after which the larva emerges as a free-swimming nauplius. This sequence connects dormancy, embryonic development, and early larval biology in a single observable system.
Saltwater provides the hydration environment, while oxygen supports the resumed metabolism of the embryo. Temperature must remain suitable for development, and light is often included in hatching conditions. Changing these factors gives students a way to examine how environmental conditions affect whether development proceeds successfully and how many larvae become available.
Their dormant, resilient state allows development to pause until conditions support renewed activity. This makes the cyst a practical example of how an animal can tolerate unfavorable periods and later resume its life cycle. In biology, that contrast helps connect stress tolerance with developmental timing and the survival strategies of small aquatic animals.
A basic protocol places dormant cysts in saltwater, supplies adequate oxygen, maintains a suitable temperature, and often provides light. The system is then observed for renewed development and nauplii release. Keeping the environmental conditions consistent helps investigators relate differences in hatching or survival to the factor being examined.
Comparing cysts exposed to different environmental conditions can reveal how those conditions influence development and survival. The resulting observations may include whether development resumes, whether nauplii are released, and how successfully the larvae persist. Such comparisons turn hatching into an experimental model for studying environmental effects on animal development.
Newly hatched brine shrimp serve as live feed for fish and invertebrate larvae, linking the process directly to aquaculture practices. The same organisms support biological studies of dormancy, stress tolerance, and life-cycle biology. Their use therefore spans both practical larval nutrition and broader investigations of development and adaptation.
