Rick:
To try to answer your questions.. your question, how big a tank
should I get? It really depends on how big of boat and cockpit size you
have and if you are doing lots of multiple days trips or not? Also, do
you fish more often for tuna than say marlin, where you'll need more
chum versus just plain hook baits.
I like to carry as much bait as I can for those times when the bite
really turns on. It never fails that when the marlin really pop is when
its the toughest time to make a tank full of mackerel! In Cabo, it's
another story with bait prices going for as much as 2 - 4 bucks a piece
for precious baits to cast and kill on trailers that don't want to eat!
How many gallons are necessary per scoop to keep the bait alive and
active for a few days at sea?
I run with the rule of thumb of 20 gallons per first scoop of sardine
or anchovies and then one scoop per 10 gallons thereafter. For mackerel
the rule of thumb I use is 10 - 15 gallons per each medium size green
back mackerel. Cabillito or spanish you can get more because they aren't
as active as the green back mackerel and do not require the spacing
between the baits when swimming in the tank.
How much bait you can pack really depends one whether the bait is
cured (been in your own private receiver or bait dock's bait receiver
for a week or more) or not and how you load the bait, ie. with a bucket
or net passes. Bucketing sardine, anchovies or mackerel from a receiver
is always the best method of loading them to the tank to avoid scale
loss which essentially causes the baits to die from dehydration through
the loss of their protective slime coat and scales. This same thing
happens to mackerel if you are careless and let a bait rub on the side
of the tank while shaking it off the hook or put a bait in the tank that
hit the deck before you put it in the tank..a definite NO NO. Don't put
a bleeding mackerel in a tank as it will pollute and stress out the
whole tank full of baits and besides it wild die from blood loss
eventually anyway.
Better to have fewer baits in a tank which will mean healthy baits,
than to crowd them and end up with a bunch of stressed out weak ones
that the fish don't want to eat.
Feeding the bait twice a day really keeps them happy so does removing
any dead decaying baits from the tank that cause a reduction in oxygen
levels. In my dock receiver and while fishing I feed my anchovies and
sardine, which by the way I refer to as my pets I get so attached to
them, instant potato flakes and tuna blood. Mackerel will eat in a
receiver or bait tank but it takes a few days and then they will eat cut
anchovies and the flakes. A little bit of frozen ground chum also is good
protein too.
For tank fill times I adjust my valves to fill the tanks in 7 - 8
minutes for green back mackerel and fill 8-10 minutes for anchovies and
sardine. I prefer a 110v Jacuzzi pump over 12v system because I don't
have to worry about air locks or pump failure. I also use circular tanks
exclusively for the best water flow throughout the entire tank. My tanks
fill and remove water throughout the water column evenly - providing
oxygen flow throughout as well as uniformed water exchange. The water
flow is pumped in a clock wise direction so the baits swim in a counter
clock wise direction. In the Southern hemisphere it would be the
opposite. I also paint the interior of my tanks painted a dark grey /
blue color and run a light above the tank not at the bottom. The dark
interior of the tank calms the baits and the light above the tank makes
the baits move to the bottom of the tank away from the light. In rough
seas this prevents the baits from getting beat up on the surface water
of the tank. In a sense, I try to make the bait tank environment as
close as possible to the ocean environment, dark and familiar and with
the sun above the water surface. Deck lights and or pole light
positioned above the tank at night works the best. For these reasons I
do not like aquarium windows in the sides of bait tanks. Ever see a bait
tank in a commercial jig boat, party boat or bait boat with a bright
white colored interior or lights shining up from the bottom of the tank
or aquarium windows? There is a reason, and in it's not cost or
cosmetics.
If you need more help on a design, email me your fax # and I can fax
you a detailed tank design for a glass or aluminum tank and who can
build it for you. Warning, having a custom tank built isn't cheap, but a
good designed tank will save you money in the long run and provide you
with primo conditioned bait to throw at hungry fish every season
thereafter. Good luck and keep those baits healthy and happy.
