Speedy Spanish mackerel shine for science in Pilbara fishing comps

Everything about Spanish mackerel screams aggression, speed and strength. 

These dynamic pelagics can reach speeds of 50kmh chasing down prey, launch many metres into the air hitting lures and can grow up to 40cm in their first year eventually reaching up to a whopping 50kg! 

This combined with their excellent table quality makes it little wonder these amazing fish are such a popular species and were at the forefront of two recent cracking Pilbara fishing events – Munro’s Mack10k run by the Ashburton Anglers Club and King Bay Game Fishing Club’s Dampier Classic. 

Due to their fast growth rates and predator-evading speed, Spaniards remain a relatively abundant species in WA. 

However, it’s important to keep tabs on mackerel stock numbers as they have declined in other parts of the country, such as in Queensland. 

Subsequently, the Recfishwest Fishing for Science team was at both events working with DPIRD research scientist Paul Lewis and fisheries manager Liv Rynvis, collecting biological samples taken from mackerel caught by competitors. In return, the team offered a fileting service for those providing samples from fish they had caught in the competition.

Recfishwest’s Fishing for Science program, supported by Woodside North West, is a community engagement program that enables local communities to better understand scientifically the fish species that underpin prized fishing experiences.

Ageing ear bones  

One of the key parts of the fish for Recfishwest Senior Operations Officer Sam Russell and Operations Officer Levi De Boni were their earbones or their “otoliths” to give them their scientific name. 

The otoliths when examined under a microscope reveal the age of the fish by displaying growth circles like the rings in a tree. Understanding the age of fish in a population is critical information to ensure they are managed sustainably.  

The otoliths and other parts of the fish were provided to DPIRD fisheries scientists to assist in their ongoing stock assessments of Spanish mackerel in WA.  

Between them, Sam, Levi, Paul and Liv took the otoliths from 93 mackerel kindly donated by participants in both competitions over the course of six days’ fishing.  

Operations Officer Levi De Boni carefully removed the ear bones or “otoliths” as seen in this image from 93 Spanish mackerel across both competitions, which will be analysed to determine the age of each fish donated for sampling to the Fishing for Science team.

If that didn’t keep the pair of them busy enough, they also managed to squeeze in running a couple of kids fishing clinics at each competition, which went down brilliantly with the kids who took part and their grateful mums and dads.  

As Sam reflected, all their efforts were greatly appreciated and welcomed at both events by both clubs. 

“It was an absolute pleasure for Levi and I to participate in these events in our Fishing for Science capacity,” said Sam. “They are such well-run events and clearly are a cornerstone of both Dampier and Onslow’s fishing social calendar.  

“It was so heartening to get such an enthusiastic response for the sampling work we were doing. We had many good and interesting conversations with the guys and some fascinated kids around the filleting table. 

“What really stood out to us was just how much people were interested and cared about the fish they caught – and we just have to give a massive thanks to all who contributed and of course, both Ashburton Anglers and King Bay Game Fishing Club for looking after us so well. We can’t wait to come back next year.”  

Fishing for Science and hard-fighting pelagics at the 2023 Dampier Classic!

With scores of spectacular catches rolling through at the recent Dampier Classic last weekend, the weigh-in scales and our Fishing for Science team at the filleting table were certainly kept busy!  

And with our latest SunSmart Fishing Clinic allowing kids to learn how to catch, handle and release a range of great species in the pristine Pilbara waters – our Dampier fishing clinic was booked out in a matter of days.  

With a fantastic community response to our Fishing for Science fish program, supported by Woodside North West at King Bay Game Fishing Club’s (KBGFC) 47th annual Dampier Classic, scores of comp entrants provided the Recfishwest team with plenty of samples of commonly captured Pilbara species such as wahoo, mackerel and tuna. 

Fishing for Science is a community engagement program that enables local communities to better understand scientifically the fish species that underpin prized fishing experiences. With each day’s weigh-in showcasing many impressive captures, competitors were happy to assist Recfishwest in taking 63 belly samples from a range of fish species.  

Other data gathered for our Fishing for Science program across the competition included the weight, condition, sex, parasites and maturity stage of each fish, providing some interesting insights for locals while allowing them to give something back to fishing.  

The kids in Dampier absolutely loved learning about the gender and biology of many different species on our Fishing for Science filleting table from Recfishwest’s Levi De Boni, with a strong flow of captures keeping the next generation of fishers entertained for days.

It wasn’t just 70-plus Dampier Classic competitors aboard 19 boats who enjoyed some great fishing action. Our SunSmart Fishing Clinic in Dampier drew in 50 local kids eager to wet a line off the shore, with plenty of great catches ranging from 10cm Moses perch to 30cm tuskfish.  

This fishing clinic introduced future fishing generations to the great species on offer in the pristine Pilbara waters and also provided Sam Russell and Levi De Boni from Recfishwest the opportunity to educate kids on how to be SunSmart under the new KBGFC gazebo – funded through a Recfishwest Community Grant – while also teaching them how to catch, handle and release fish correctly.  

“This was Recfishwest’s biggest attended SunSmart Fishing Clinic to date with plenty of fish caught throughout the whole three-hour clinic. It clearly outlines how important fishing is to the Pilbara community when our clinics rapidly book out with dozens of kids all buzzing to wet a line,” said Recfishwest Senior Operations Officer Sam Russell.  

“A big thanks to the Dampier fishing communities, King Bay Game Fishing Club and SunSmart for allowing us to run these clinics and actively engage with hundreds of Dampier and Karratha locals again for 2023 – and a big kudos to our Fishing for Science partners Woodside Energy for supporting this great community program that continues to expand across northern WA.”  

The smiles tell the story! Here is some of many great catches from our packed-to-the-rafters SunSmart Fishing Clinic in Dampier, with more than 50 kids learning how to catch, handle and release fish.

President of KBGFC Leon Brislane has helped coordinate the Dampier Classic for the last three years and has seen first-hand the importance and growth of this renowned fishing competition and Recfishwest’s Fishing for Science program throughout our northern communities. 

“This annual competition always brings loads of families and friends together to share a beer, have a laugh and catch some top-quality fish in one of the best fishing locations in WA,” said Leon. 

“The kids can’t get enough of the Fishing for Science program and they are always super-excited to become engaged with the Recfishwest crew taking fish samples. It always leads to fun ‘guess the fish gender’ games and they also receive an invaluable biology lesson to better understand these great species of fish. 

“A big thanks to all of our sponsors for their generosity in helping support the King Bay Game Fishing Club and this great annual event.”

A big Recfishwest thanks to the Dampier community and the King Bay Game Fishing Club for their warm hospitality during the 2023 Dampier Classic.

Dampier community fishes for fun and for science!

We had a fantastic response to our Fishing for Science fish sampling table and fishing clinic in Dampier coinciding with King Bay Game Fishing Club’s recent Dampier classic.

The great response to these activities and the dozens of boats in the competition shows just how important fishing for regional communities continues to be.

Wahoo, Spanish mackerel, queenfish, longtail tuna, barracuda and golden trevally – these were just some of the species local anglers landed throughout our five-day visit to the northern coastal fishing jewel.

Our Sunsmart Fishing Clinic saw more than 40 eager kids wet a line off the shore, with plenty of great catches of species such as bluebone and stripey snapper providing great memories and snaps for the next generation of anglers.

We had a great time showing future generations how to safely catch, handle and release fish!

Following the Sunsmart Fishing Clinics in the mornings, the icing on the cake for our Recfishwest team was the many fish given to us to sample for our Fishing for Science Program at the end of each day’s weigh-in from 67 competitors wetting a line from 21 vessels.

Fishing for Science is a community engagement program that enables local communities to better understand scientifically the fish species that underpin prized fishing experiences.

In total, more than 50 fish across 15 different species were brought to the sampling table, for measuring, sexing and having belly tissue samples taken to freeze for future scientific studies and monitoring of our fish stocks.

Other data gathered for our Fishing for Science program across the competition included the weight, condition, sex, parasites and maturity stage of each fish, providing useful knowledge for locals while allowing them to give back in protecting our fisheries.

Sam Russell and Danielle Hartshorn always had a great bunch of kids eager to see the fish gender reveals!

Operations Officer Sam Russell said both the fishing clinics and positive engagement with the competition participants provided invaluable information on the importance of these special ocean habitats to our northern communities.

“A big thanks to the Dampier fishing communities, King Bay Game Fishing Club and Sunsmart for allowing us to run these clinics and engage with hundreds of Dampier and Karratha locals again this year – and a big thanks to our Fishing for Science partners Woodside Energy for supporting this great community program”
