The ROV for Aquaculture
 Why
take on the risks and expense of human dives? Control fishery
operations by seeing what's happening beneath the surface. Without
divers, cut fish loss through net inspections, find expensive
lost equipment, and perform regulatory compliance work.
Slip
the 8-pound VideoRay (remotely operated vehicle) into the water
from a raft or land. With you at the remote controls, the VideoRay
sub travels through the water, capturing crisp video.
Survey
sea beds, inspect and sample polluted sites without spreading
disease, recover morts, and check the condition of cages,
quays, pipelines, cables, hulls, and moorings. Starting at just $6000 USD,
the VideoRay shows payback quickly.

Farming of the Great Scallop (Pecten maximus) is a growing industry
with a great potential in Norway. The last five years have brought
an increasing interest in commercial diving for scallops, and as
a result, the natural population in some areas has almost vanished
or been significant reduced. In response, there has been significant
effort to establishing Great scallop farms.
Field experiments during the last years have shown that the best
method of keeping scallops is to release them on the seabed within
a fenced area. In this environment, the scallops will be kept in
an almost natural habitat and isolated from the main predator -
brown crab (Cancer pagurus).
Keeping the scallops in farms like these calls for equipment that
allows for easy monitoring of the site without constantly using
divers. Sub Aqua Tech owner Eivind Aarseth uses his VideoRay Pro
Inspection System for inspection in scallop farms and searching
for sites suitable for scallop farming. Aarseth has worked for
the Norwegian Directorate of Fisheries as a local Fisheries Advisor
since 1992 and recognized the VideoRay’s value for aquaculture.
Sub Aqua Tech offers services for the aquaculture industry, specifically
underwater inspections, aquaculture advisories, environmental investigations,
and the sale of VideoRay ROVs (remotely operated vehicles). Sub
Aqua Tech, located in Tipphaugen, Norway, performs services with
the ROV as a safer, cheaper, and easier alternative to inspection
by traditional divers.
Weighing only 8 pounds/3,6 kg, the VideoRay is remote controlled
from land. The tiny submersible sized 35 cm x 22.2 cm x 21.6
cm travels up to 500 feet deep, sending video footage from its
camera
eye to a monitor on land. The video includes information about
time, date, depth and heading. The sub has a high quality light
sensitive (0.5 lux) color video camera, which provides high-quality
pictures and video. Two 20-watt halogen lights with variable intensity
illuminate the depths. All information seen on the video screen
and can be recorded on ordinary VHS or DV tapes.
“The VideoRay unit is very quick for this purpose,” says
Aarseth. “I can have a look around on the seabed at ten sites
in the same time as it would take to look at one site with traditional
diving. Plus, the recorded picture from the high quality camera
on VideoRay, combined with on-screen displayed time, date and depth
gives very good information about where and when the inspection
was done. The VideoRay is a very powerful tool.”
Using the VideoRay, Aarseth documents underwater conditions and
helps companies comply with government regulations. Highly maneuverable,
VideoRay is suitable for inspecting salmon, halibut, and scallop
farms. Farms call on him to perform surveys of sea beds to establishing
new sites for farming and inspect and sample polluted sites without
spreading diseases. Aarseth also inspects cages, quays, moorings,
underwater pipelines and cables. For private boat owners and small
boat clubs, he inspects vessel hulls (zinc anodes, propellers,
damage at hull) and moorings.
