Lumpfish, Cyclopterus lumpus, distribution in the Gulf of Maine, USA: observations from fisheries independent and dependent catch data
This study was funded by NH Sea Grant to document wild lumpfish populations over time and in conjunction with a warming ocean. It is important to know about wild lumpfish dynamics if they are to be harvested in US waters for use as a cleaner fish in salmonid farms.
Evaluation of an experimental kelp farm’s structural behavior using regression modelling and response amplitude operators derived from in situ measurements
An experimental kelp farming system for exposed ocean conditions was designed, deployed, planted with kelp and instrumented for evaluation of its dynamic response to ocean waves, tides, and currents.
Tolerance of juvenile lumpfish (Cyclopterus lumpus) to high rearing densities
Lumpfish can be used as cleaner fish to remove naturally occurring parasites from salmonids, like steelhead trout. We strive to improve lumpfish production in the hatchery for this purpose. This publication details a study showing the effects of rearing lumpfish in varying densities.
Resolving the term “offshore aquaculture” by decoupling “exposed” and “distance from the coast”
The terms “offshore” and “open ocean” have been used to describe aquaculture sites that are further from the coast or in higher energy environments. Neither term has been clearly defined in the scientific literature nor in a legal context, and the terms are often used interchangeably.
Effects of light and density in rearing Lumpfish (Cyclopterus lumpus)
While lumpfish are proven cleaner fish and eat parasites in salmonid farms, in the hatchery, they sometimes eat each other. We manipulated lighting and fish density in the hatchery to provide lumpfish growers with guidelines to minimize aggressive fish behavior.
Combinatorial metabolomic and transcriptomic analysis of muscle growth in hybrid striped bass
This collaboration between UNH (Prof. David Berlinsky and Dr. Linas Kenter) and the “StriperHub” focused on a prevalent issue in commercial aquaculture of why some fish grow fast and some grow slow. Results demonstrated novel insights into the molecular regulation of growth pathways not only important for finfish aquaculture but also broader vertebrate physiology.
Design, Deployment, and Operation of an Experimental Offshore Seaweed Cultivation Structure
This project was funded by the DOE MARINER program to develop technologies that enable large scale macroalgae cultivation for the purpose of generating material for human food, animal feed and biofuel.

Laboratory investigations into alternative baits for the channeled whelk (Busycotypus canaliculatus) fishery
Channeled whelk are fished commercially along the US Atlantic seaboard but the fishing industry relies on baits containing horseshoe crabs, an unsustainable ingredient. This publication details a laboratory study in which we created and tested baits composed of invasive species and other low-cost ingredients and found possible alternatives to horseshoe crabs.
Integrated multi-trophic aquaculture of steelhead trout, blue mussel and sugar kelp from a floating ocean platform
Our CSSS integrated multi-trophic efforts are always ongoing. This publication details how we can benefit the coastal environment and the seafood community utilizing this innovative approach to aquaculture.

Mooring tension assessment of a single line kelp farm with quantified biomass, waves, and currents
Kelp farming (Saccharina latissimi) has seen an increase in the Gulf of Maine. This publication details load and tension statistics measured at an experimental site in Saco Bay, ME. These data can ultimately help optimize future farms to produce a healthy kelp product.
