Good job bulldog.Good ole middle of the bay bream.

Top kingie boys.Theyre getting bigger every season.Wont be long till the kingfish traps will be back.

Yeah Dougs your pretty keen mate.I wish i was as motivated as you.Youre right Jewhunter,didnt look at the bloody moon phase did i? Dead giveaway i only catch soapies in the smaller sizes.LOL.Ive been shown up already.Yeah ive actually had dreams or sweaty nightmares of catching that famous Captain Cook bridge Jewie.25-35kg would be nice.Now im really starting to get excited being privilidged to fish and learn from a couple of fishing gurus.Ill definately take you up on that one Byron.I dont have a big boat,but i reckon it may just do what we want.Yeah well ive got big ears and a small mouth.I listen alot and dont talk much. LMAO.Ill send some pics to you to see if its suitable for you blokes.

Gees someone must have got a Jewie last night/early morning.Seemed like conditions would be good.High barometric pressure,hight tide 3.30am.Or are you fellas keeping them secret? Lol.

1020 fish a plenty.TOP CATCH BOYS.

Gday raiders.Just wondering if negative barometric/low pressure system conditions would have an effect on squid? Would it affect them? And has anyone noticed if their catches of squid are higher during conducive conditions according to the barometer? Just a thought. Youve opened a a whole new world jewgaffer.Lol. Thanks. Heres a little something i found that may be of use to someone. Pressure, whether in the air or in the ocean, is expressed by scientists as units of “atmosphere.” One atmosphere is defined as the pressure caused by the weight of all the overlying air at sea level—or 14.7 pounds per square inch (psi). Atmospheric pressure is often called barometric pressure because it can be measured by the height of the mercury column in a barometer. Changes in barometric pressure, therefore, indicate capricious weather. In general, low-pressure systems bring unstable conditions, often with precipitation and clouds. A rising barometer means high-pressure is approaching, the harbinger of stable and clear skies. How much do fish respond to these day-to-day fluctuations? Consider that a normal value for barometric pressure is about 30 inches. Strong high pressure is about 30.70 inches. A powerful low, such as during a hurricane, can reach down to 28 inches or less. The difference between these two extremes (2.7 inches of barometric pressure) is equal to about .09 atmospheres. The barometric pressure difference from a simple passing cold front is only about .06 atmospheres. The rate of a falling barometer also tells us how fast a low-pressure storm is approaching. A slow-moving storm would have a dip of about .02 to .03 inches of barometric pressure per hour; a fast-moving storm will drop the barometer about 0.05 to 0.06 inches per hour. Simply stated, barometric pressure does not change quickly enough to magically turn the bite on or off. It certainly is one of the ingredients in the overall weather process, but temperature, cloud cover, wind direction and speed, and humidity can also affect fishing conditions. More importantly, the rate and amount of change in barometric pressure is insignificant compared to what’s going on below the surface. Beneath The Squeeze Pressure in the ocean, called hydrostatic pressure, increases with depth due to the weight of the overlying water. Water is almost 800 times denser than air; thus, hydrostatic pressure increases much more rapidly than atmospheric pressure. If you swim or dive just a few feet below the water’s surface, you feel this rapid increase in pressure. At a depth of just 32.8 feet in the ocean, the hydrostatic pressure is equal to the pressure from the entire weight of the earth’s atmosphere as measured in pounds per square inch. In other words, at 32.8 feet, the total pressure, due to the weight of both the atmosphere and the water, is two atmospheres. At 65.6 feet it’s 3 atmospheres, and so forth. Fish can tolerate hydrostatic pressure because they have a swim bladder containing a volume of gas, which they adjust to equal their environment. This enables most fish to comfortably make small and quick up or down movements in the water column. In the ocean, four main factors can change the hydrostatic pressure in the fish’s world. First, a fish naturally changes pressure around itself by making movements associated with feeding, swimming about, avoiding predators or trying to loose a hook. A small move can result in a relatively large pressure variation. For example, going up or down just 3.28 feet will decrease or increase the pressure on a fish by 1/10 of an atmosphere. One tenth of an atmosphere exceeds any reasonable change that might occur due to a fluctuation in barometric pressure. Equally important, when barometric pressure rises or falls, it can take more than a day to equal the change in hydrostatic pressure that a fish experiences in seconds during its normal up or down movements. Second, tides can alter hydrostatic pressure. Assuming the fish stays in the same position, even a small three-foot rise in tide will increase the hydrostatic pressure by about 0.09 atmospheres. A low tide would decrease the hydrostatic pressure by a similar amount. Thus, within about a six-hour period from high to low tide, a fish would experience a fall of about .18 atmospheres of pressure. This is about twice what could be expected from the barometric pressure going through a major drop during a hurricane. Third, waves make rapid and continuous changes in hydrostatic pressure. Two-foot waves, for example, will produce a change in pressure of about .06 atmospheres. This rapid change correlates to the period of the waves—about four to six seconds. Higher pressure comes when the crest passes; lower pressure occurs under the trough. When a storm approaches a coastal area, the waves, and the increase in hydrostatic pressure, will be considerably higher than during calm-weather periods. The weight of the air itself is the fourth influence on hydrostatic pressure, but its effect is quite gradual. Barometric pressure associated with a major storm will dip (depending on the system’s rate of speed) by only .002 to .02 atmospheres per hour. This gives fish considerable time to make any necessary adjustments. When compared to the effects of the tide, waves, and normal movements of the fish in the water column, changes in hydrostatic pressure caused by barometric-pressure are trivial for saltwater fish. Even a dramatic change in the barometer will be lost to the everyday pressure changes experienced by fish under normal oceanographic conditions. It’s a happy notion that one could simply consult the mercury column each morning to know whether it’s a better day for work or fishing, but it’s unlikely that barometric pressure alone can trigger the sudden bite that angling’s common wisdom often asserts.

Get yourself a Downrigger mate.And learn how to use it properly.Youll love it.

Top Post as usual Jewgaffer.Funny how you mentioned about the sharks coming in.There were 3 sighted close to 3 Sydney eastern suburbs beaches today.Including 2 hammerheads.Man you know your stuff.Thanks for sharing that mate.

Yeah.Theyve been there for a while.They would have some good growth on em.Should be producing some results by now.Looks like the Fisheries study on em may be a dud.Should be conducting our own study.The Bay fishos study.Lol.Seeing we fish there regurlarly. Wonder how the others that were put in elsewhere are goin? I read somewhere on here that a Raider didnt have much luck at all.With the Port expansion and all the damage that its goin to do.How can they possibly conduct a study when thats goin on? And the Desal plant around the corner at Kurnell.Fair dinkum.What are they doin with our fishing license fees? Definatletly makes you wonder.What do yas reckon? Thanks.

Hey fellas,waswondering if anyones had any success in Botany bays 6 artificial reefs that were placed a while ago.Good for yakkas.But how about any other species? Thanks Raiders.So much knowledge here i love it.

Hey Fisheroo.Just go around Towra weed beds on the edges where it meets the sand.Anchor up and burley with bread and pilchards,but make it real fine so they dont get bloody full of your burley.And after a while they will come to you.Just use a small hook with some pilly on it,and a splitshot sinker about 30 cm above the hook.They love it.Perfect size too.Downrigging,and trolling with yakkas around Mol pt,the markers and the lighthouse are pretty crazy at times.The Kings are getting much bigger than last season.And theyll be bigger again next season.Its only a matter of time before the Kingy traps come back in.Theyll be in plague proportion within the next ten years.I wont be going out for a while as my bloody gearbox on the outboard is gettting rebuilt.Ill take some pics when i go out next mate. I fair dinkum love the Bay and the Georges.Top fish in this system.Thanks.

I just answered my own question.Loads of yakkas at Towra.And plenty of Kings to eat them.

Gday Raiders.Was wondering if any yakkas hang around Towra,or is it too shallow for them?

Yeah gidday fishlexic,i was starting to think that nobody knew what i was taliking about.So it definately improved your mates results.A certain charter boat operator in Sydney swears by them.Saying the side with the Shark on gets followed all the time,and the side with the ball gets ignored.Watching it through StrikeVision.Thanks for your feedback mate.

Gidday raiders.Im wondering if anyone has had any experiences with the Shark canonball used for downrigging? Ive been checking it out on the net and have just bought a 10 pound one.Theres also a video on Youtube showing it in action,under Shark canonball.Im sure the regular lead ball and the other ones around dont attract the predators to the bait or lure like this does. Thanks.
