Kendall said that the difference is that the shrimp are
not as likely to come to the edges of the ponds.
On the Currie farm, ponds which had been used for
fish production are being used to grow the shrimp. On
ponds built for shrimp production, such as those on the
Kendall farm, the bottoms slope more. Also, the drain
pipes are much larger. The larger drains enable the
producer to open the drain pipe and then catch the
shrimp in a net as they come out of the pipe. The Currie
ponds, however, are not sloped enough and do not have
large enough drain pipes to harvest the shrimp in that
way. As a result, the traditional seine is used to
gather the shrimp into a small pocket where they are
dipped out by hand.
While the larger drains on custom built shrimp farms
reduce the amount of manual labor because the nets can
simply be lifted out and dumped, there are also
advantages to the seine. On the Currie farm, if he has
an order for 150 pounds of shrimp, then that amount can
be seined. If the main drain is opened on a shrimp pond,
then the producer had better be ready to do something
with all the shrimp in the pond.
Once the fish is out of the pond, then the same
procedures are followed on both Kendall's and Currie's
farm. The first step is "chill killing" the shrimp by
placing them in a bath of cold water. The shrimp are
then hand sorted to remove any small fish, sticks or
other things caught in the nets.
The next step is to pack them in ice for shipment or
for sale.
On the Currie farm, the shrimp harvested this past
week were headed to a South Fresh processing plant in
Utah, Alabama. At that plant, they were individually
quick frozen so that they can be packaged and stored for
later sale. That process extends the market period
somewhat and reduces the pressure for immediate sale..
Certainly the telling factors in whether or not
marine shrimp will be a financially feasible project in
this area will be a comparison of input costs and
returns or yields, whether figured on a dollar per acre
or price per pound basis. It is still too early to
determine either of those figures because the harvest is
just now underway.
One thing is certain, however. It is much more
expensive to raise shrimp than to raise fish. Currie
said that he believes this year that it may cost him
five times as much to raise shrimp as it would to raise
fish, while Kendall said that he believes that his cost
will be two to three times the cost of fish production.
Certainly, Kendall noted, labor costs are higher for
shrimp than for fish. Also, shrimp need more aeration
than fish, another expense. It is also expensive to
obtain the post larva shrimp and to acclimate them
before they are placed in the ponds.
According to Kendall, while oxygen levels are not as
big a factor as with fish, shrimp do better when their
water is moving. On his ponds, water drains from one end
of the pond to a ditch and is then pumped back in the
other end of the pond to keep the water moving.
A major part of the financial feasibility of shrimp
also depends on the issue of marketing. So far, the area
growers do not have the volume and dependability to
attract large scale distributors. As a result, they rely
on smaller sales to grocers, restaurants, to individuals
and through outlets such as farmers' markets.
Kendall, who had a small test pond last year, was
excited enough about the feasibility of shrimp to expand
to 15 acres this year. As of this past week, he has
harvested one of his three ponds, averaging about 1,000
pounds of shrimp per acre, "not quite as good as last
year." He said that this year, he had made some mistakes
and will learn from those mistakes in the future, making
changes in his operation as needed.
On the Currie farm, one two acre pond had produced
over 2,300 pounds of shrimp with one full seining and
two partial seinings. He planned to seine the pond at
least one more time because when the net was pulled it,
shrimp were jumping over the net or possibly escaping
under it. Then, when the seining fails to produce enough
shrimp to justify the labor, the crew will drain the
pond to get the remaining shrimp.
The taste of the marine shrimp grown in the fresh
water ponds is very good, though slightly different from
the ocean raised shrimp. Part of that difference may be
due to lower iodine levels, which could make the pond
raised shrimp more attractive to people who are
sensitive or allergic to iodine. Also, the veins on the
pond raised shrimp are much smaller because of the fast
growth rate, and they can be eaten without having to
devein them.
Kendall is excited about the long-term feasibility of
shrimp production. "We are hurting so badly here in
Southeast Arkansas," he said. "We might have found
something that our soil and water is well adapted to."
As an example, he noted that the growth rate on the
farms in this area are higher than for salt water shrimp
farms in South America.
The market for salt water shrimp grown in Southeast
Arkansas will be to the north, Kendall predicted. He
said that he
While Kendall grows only the salt water species of
shrimp. Currie has both salt water and fresh water
varieties. "There's a lot of difference," Currie said.
One difference is in the density per meter of water. The
salt water species is very sociable, and so many more of
them can be placed in each square meter of water than
the fresh water species. Naturally, the greater the
density, the smaller the shrimp will be.
Currie noted that he is not interested in growing
popcorn shrimp, where the density is very high, and the
crop is harvested and then a new one started. As Kendall
said, what they aim for is quality size gourmet-tasting
shrimp.
A sample from the Currie pond this past week
indicated that they are meeting that goal.
