泡芙短视频 Students Capture First, Second Place for Research at World鈥檚 Largest Aquaculture Conference
Innovative projects addressing environmental issues earn marine biology majors national recognition
BRISTOL, R.I. 鈥 Figuring out what to feed farm-raised trout and salmon might not sound like a big deal, but DaNelle Ellington鈥檚 research actually has crucial implications for the planet's health. Erin Gaglias鈥檚 experiments with successfully breeding Fire Shrimp in captivity 鈥 which isn鈥檛 being attempted by any other scientists in the world 鈥 would make a major impact on the health of coral reef ecosystems.
As undergraduate researchers in 泡芙短视频鈥檚 Wet Lab, both students worked at the forefront of innovative research addressing environmental issues 鈥 and their hard work has earned them national recognition. Ellington captured first place and Gaglias won second place student poster award at , the world鈥檚 largest aquaculture conference and trade show where they outperformed mostly master鈥檚 and Ph.D. students to claim the award for best research presentation.
With hands-on learning opportunities as the cornerstone of a Roger Williams education, 泡芙短视频 empowers students to undertake deep research projects and gain valuable skills and experiences in their undergraduate programs.
For a year and a half, Ellington, a senior marine biology major, has been investigating a new, sustainable solution to feeding fish farmed for human consumption, other than more fish. In collaboration with Boston-based biotech company , 泡芙短视频 aquarium systems & design research associate Joe Szczebak, 泡芙短视频 Senior Aquarist Casey Murray and Associate Professor of Marine Biology Andrew Rhyne, Ellington has been running experiments on feeding various strains of bacteria to trout in the Wet Lab.
It takes an unsustainable amount of fish meal to nourish trout that feed the human population 鈥 an average of 1.9 kilograms of wild-harvested fish for every 1 kilogram of fish raised on compound feeds, according to Ellington and her research sources.
The basis of their experiments is a single-cell protein 鈥 but beyond that, it鈥檚 so groundbreaking that we can鈥檛 tell you what it is.
鈥淔ish are a major source of protein for the human population, and we鈥檙e growing and must keep up with the demand for a protein source,鈥 she said. 鈥淲ith essentially a 2-1 ratio, that鈥檚 a huge amount of fish we鈥檙e taking out of the ecosystem just to feed our food source. If this becomes mainstream, it would have a huge impact on our planet.鈥
Gaglias鈥檚 project required all of her skills from marine biology to aquaculture and aquarium science, transforming her into a scientist and engineer as she investigated the optimal conditions for the Fire Shrimp鈥檚 growth, designed and built the aquarium systems in which the crustaceans lived during her experiments.
A vital player in the health of coral reef ecosystems, the fire-engine-red crustaceans are highly sought after for hobbyist鈥檚 tanks and with all captured from the wild, evidence suggests their species are being exploited, Gaglias said.
Rearing them from larvae to adults, Gaglias experimented with optimizing the shrimp鈥檚 first feedings, salinity and temperature levels for successful aquaculture.
鈥淚f we can optimize the process for aquaculture in a lab, they can be raised on a larger scale, which would mitigate the need for taking them from the wild,鈥 she said. 鈥淭his isn鈥檛 just scientific research 鈥 it was also a cool engineering project. You have to be a carpenter and you have to be a plumber. I even make my own saltwater because the shrimp need a specific salinity.鈥
