About Skipjack Tuna Fish Biology and Habitat
Skipjack
tuna fish is widely known as light tuna or chunk
light tuna for canned fish product. They often be caught to be sold to fish
factory and the manufacturers will process them as canned skipjack tuna with
delicious taste. Some of skipjack tuna meats have been sold in frozen state,
raw state, and the most popular one is canned product because not all people
can manage to get fresh high quality skipjack tuna meat. Most of skip jack tuna
fish do not have scales on their majority of their body and unlike other tuna
types; skip jack cannot control their own body temperature because they have
been considered as cold blooded type of fish.
Biology and
the habitat of skipjack tuna fish
Skipjack body can grow more than 4 feet or
over one meter in length and they can weight more than 70 pounds for skip jack
tuna which live in the Pacific Ocean while Atlantic skipjack can grow up to 3
feet or about one meter in length and can weight around 40 pounds. Compared to
the other tropical tunas, they have short life span about 7 to 12 years old. Majority
of the skipjack tuna fish body have this
lateral and corselet line from their head and across their body as a marker.
Female skipjack depending on their size can
produce eggs from 100,000 to 2 million eggs at a time. The procedures are these:
Female skipjack tuna will reproduce through the broadcast spawning; the tuna
sperm and the eggs are released into ocean waters at once in the same time. And
after fertilization those eggs will be hatched.
Just like other types of tuna, skipjack
tuna is an opportunities predator which prey various species of fish such as
mollusks, cephalopods, crustaceans, and the other tuna as well. While larger
size of fish likes sharks, billfish, and large tuna eat skipjack tuna fish.
Skipjack tuna can be found across ocean in
all around the world like subtropical and tropical temperature waters. There
are 6 different populations or habitats of skip jack tuna such as:
-
Eastern Pacific
-
Central Pacific
-
Western Pacific
-

Skipjack like to swim around in an open
ocean by making a large group because they are a fish pelagic type and usually
can be seen swim on the surface to depths to 260 meters or 850 feet. Throughout
the day they will appear near the ocean surface while at night they tend to
hide themselves in order to not be seen. Just like other tunas in need to
reproduce and find food sources, skipjack will highly migrate from one area to
another area in large-scale migrations. Both yellowfin and bigeye tuna are
often found to join this large scale of migrations as well. And that’s why some
canned skipjack tuna fish may be mixed with
yellowfin and bigeye tuna because they are not separated during harvest.
Skip jack are the smallest and the most
abundant type of tuna and fish industry like to process them as canned fish
product with label of light tuna fish or chunk light tuna. Due to the high
demand of skipjack tuna and overfishing problem, it has been reported that the
population of skipjack tuna somehow become more and lower than before which
become a threat. This issue apparently applied for yellowfin and bigeye tuna as
well.
Skipjack tuna like to be caught alive
because they will make a great lure or bait for the other fish during fishing
sport. They can be used for wide variety of fish like sharks, larger tuna, and
marlin. Skipjack tuna fish meat is very oily
and bloody and thus makes it a good bait to catch larger fish and not to
mention some people considered the texture to be good to be eaten.
Skip jack tuna offers a lot of nutrition as
well including protein, calcium, minerals, vitamins, and omega 3 fatty acids.
Although its sodium considered to be high so people need to limit themselves
when consume canned tuna fish meat per week especially if for children and
pregnant women who more sensitive. That’s several information regarding skipjack tuna fish and hope it will be
useful to learn about skipjack tuna before catch or eating them
