HYBRID STRIPED BASS
The
HSB has only recently been recognized as a predator fish suitable for small
ponds in Texas.
I began stocking HSB in Nova pond in the spring of
2003, stocking about 30 of the 4 to 6 inch fish each spring and fall.
The growth characteristics of the HSB in Nova pond have been such that
the fish will double in size the first growing season usually reaching about 1
pound, then double in size again the second season reaching about 2 pounds,
then reach about 4 pounds after the third growing season.
Below,
typical HSB after two seasons of about two pounds and typical HSB during the
third growing season of about three pounds. These fish are spectacular fighters
on light equipment, especially on fly equipment. They serve as the "virtual"
catfish in Nova ponds providing an excellent eating, hard fighting, put and
take fishery. They do need artificial feeding in order to achieve the weight
gains mentioned herein. The eventual size of these fish in Nova pond is yet to
be determined. Note: the seller of these fish
stated " they should easily reach 8 to 10
pounds in your pond"
 
Update Summer of 2005:
One disturbing characteristic of
this fish, as relates to its appropriateness for small southern ponds, has
developed. When the HSB in my ponds reach a size over about three pounds, they
become extremely vulnerable to angling mortality during high temperature
months. More specifically, during the summer of
2005, every HSB caught over three pounds,
independent of tackle used, in water temps above 80 degrees did not survive the
experience. More research this summer will determine if that was an anomaly or
a flaw of this otherwise great fish. If you can't catch a HSB over three pounds
without killing it in the Texas summers, it has very little value in terms of
meeting my pond objectives. Stay tuned for next summers experience
Update Summer of
2006: This summer in our
part of Texas was very hot and very, very dry. Once again, any HSB that I
caught over about 3 pounds did not survive. More disturbing perhaps was the
discovery of a few skulls of the largest HSB in the ponds....they were dragged
up to the house by my black lab "Duke". I suspect HSB mortality due to water
quality problems or simply that the HSB is
unable to be sustained in my ponds above certain
weights in the summer. Would very much like to hear from
other HSB pond owners, especially in Texas, to see if anyone else experienced
any HSB mortality this summer.

Update
Fall of 2006: The HSB that survived the summer drought and high temps are enjoying the
respite from the trying Texas summer. Pictured below are a couple of about 4
pound HSB taken this fall. No large class
fish over 5 pounds survived the summer.
 
Update 04/14/07:
Due to the problems encountered with this fish
last summer and the previous summer before that
and the corresponding tremendous success of the
LMB during the same period in all ponds, all HSB
will be removed from all ponds on Meadowlark
Ranch. Pictures of these fish as they are
removed will be provided from time to time.
Update 05/26/07....removing the HSB

SUMMARY OF HSB EXPERIENCE on Meadowlark
Ranch:
The original intent of stocking these
fish in this experiment was three-fold: 1) to find a
pond predator that would provide fast action on
medium(up to 5 pounds) and large size fish( 8 to
10 pounds was the sales talk from the fish
seller), 2) to overcome the hook shy conditioning
prevalent in other pond predators and 3) provide
good eating fish for the family. Sadly, the HSB
fulfilled only objective 3 and failed very badly
on the others.
Relative to objective 1, the HSB
grew initially very fast but were soon surpassed
in size by LMB in the same pond. Several LMB
ranging from 6 to 10 pounds have been caught in
the same pond while the HSB have only reached 5
pounds. Further, HSB at that size (over 3 pounds
in fact) experienced 100 % angling mortality in
this pond in summer...meaning if I wanted to raise
a HSB over 3 pounds, I had to stop fishing from
May to October...not a good thing! In addition,
several HSB in the 4 to 5 pound class died without
any angling pressure last summer.
Relative to objective 2, it was a
non-starter from the beginning. Why I ever thought
a fish wouldn't become hook shy after being caught
in a pond, I don't know. If every HSB that was
caught was removed (no catch and release) then
perhaps the hook shy condition could be avoided
but then only small fish would be available.
HSB become conditioned to artificials as fast or
faster than even LMB and the only way they can
reliably be caught are at the fish feeders...again
not a good thing!
Relative to objective 3, the HSB provided
excellent table fare...at significant cost because
of the requirement for artificial feeding.
One last comment, the HSB prefers high-protein pellet
food, but if it is not provided in sufficient
amounts, the HSB will put tremendous
pressure on a forage base in a relatively large
pond that has deep open water and not a lot of
structure. My experience in Nova
pond consistently showed that as HSB were removed,
the LMB grew larger.
To anyone reading this and considering
HSB in your pond, I hope you experience
better results than I did. East Texas is a tough
climate with water temps above 80 degrees for many
months and very dry summer conditions which do not
provide a flushing for the pond. The
requirement for artificial feeding of HSB can greatly
further degrade the water quality in summer
months, even in aerated ponds such as this one. If
I had been a little smarter and listened a little
less to the sales talk, I would have remembered
that both parents of this fish, the Striper
and White, prefer slow moving open water when in very large
lakes. With that heritage, it should not
have surprised me that they would fail in an
East Texas pond.
Post Script 08/13/07:
I have now confirmed the death of small HSB
without any angling intervention. The fish
pictured below were found this evening floating in
Half Pint pond. I check the ponds every day and
had checked this pond that morning without seeing
anything unusual. By tomorrow, the next day, there
would have been no evidence of these fish dieing
and I would have never known it had happened. This
is the first positive confirmation of small HSB
mortality during summer. Previously, only fish
over about 3 pounds had died during summer temps,
but I always suspected other HSB were also dieing.
Clearly, HSB are not suitable for my ponds and
Nature will remove them in due course if I don't.
Post Script 08/14/07:
The HSB die-off has continued today with 5
additional floaters showing up....in the picture
below 4 of them are in the foreground and one is
in the background in the upper left corner. I
wanted to remove these fish anyway and it seems
that Nature is accommodating my intents very well.
Notice the surface rings of TGG's feeding on
Gambusia...all is well in the pond except for the
HSB.
