The Barramundi Life Cycle
fishing is the single most popular fishing activity in tropical
and sub tropical Australia. Hinchinbrook is renown for its vast
mangrove wilderness and fine barramundi fishing. Located midway
between Townsville and Cairns on the Coast from Ingham the Hinchinbrook
shire is a great place to spend a little time barra fishing.
channel has had no commercial barramundi harvesting for more than five
years now resulting in many more breeding stock in the channel
for future enhancement. Restocking has also been taking place
for many years now by the Hinchinbrook Restocking Group and supported
by the local Ingham Rod and Reel fishing club.
Adventures conducting Barramundi fishing holidays and day tours
from Lucinda at the southern end of hinchinbrook channel since 1992. Whether it be lure casting or fly fishing visitors have
the opportunity to experience some of the best wild stock barra
fishing in the north. Fishing for and catching wild Barramundi
is the ultimate angling experience, barra in the wild are wrily,
cautious, and hard fighting.
The Barramundi produce eggs between the months of September and
March with the build up period from October to December being
the most important.
eggs and larvae require salt water and spawning normally takes
place in Marine bays and river mouths Juvenile Barramundi [now200-300mm]
migrate up the rivers and its freshwater wetlands.
If the young do not have access to freshwater they will probably
remain in coastal and estuarine areas to mature. After three to
five years most of the freshwater Barramundi migrate back to the
ocean to spawn
How to tell the age of Barramundi:
Length to age relationship is:
- 1-Year-old 30-40cm long,
- 2-Years-old 50-60cm long,
- 3-Years-old 60-80cm long,
- 8-Years-old 1 Metre long
When do Barramundi change sex?
Barramundi change sex from male to female.
The size of the Barramundi can be a good indicator of the sex
of the fish.
Most Barramundi mature as males [about50-60cm] and start to change
sex to females at around 90cm but only if they live in saltwater.
What do Barra eat? Barra are fairly lazy opportunistic
feeders they eat just about anything that lives in or around the
water including prawns small crabs and even each other.
The size of the prey is largely determined by the size of the Barra.
A larger Barramundi's diet consists of 60% fish and 40% crustaceans
[mainly prawns],smaller barra eat mainly prawns.
This will vary according to where the fish is living.
How do Barra feed in dirty water?
Vision is probably limited in dirty water.
Barramundi utilise what is called a lateral line,which is a sensory
organ that runs down both sides of the body.
The lateral line enables fish to detect vibrations in the water
and so be able to locate prey and avoid predators.
The question of whether it is the colour or action of the lure
that attracts the fish is difficult to answer,however it is probably
a combination of both.
- Barramundi have been recorded up to 150cm long and with weights
in excess of 40kg.
- Barramundi are thought to live to around 20years of age.
- Large female Barramundi can produce 32 million eggs in a
- Barramundi inhabit areas where the water temperature ranges
between 20 to 35 degrees Celsius.
- Barramundi can travel great distances in their life; one
fish was recaptured 600 kilometres away.
