A history of our dolphins in Mandurah
1 October 1990- 10 bottlenose dolphins were found in Lake Goegrup,2 unfortunately having already died. 8 were rescued,and freeze-branded 01 to 08 then released under the new bridge. All were males and measured approx. 2.2 metres in length.
3 February 1991- 2 bottlenose dolphins were trapped in Lake Goegrup, already freeze-branded 02 and 03. They were released under the new traffic bridge.
13 January 1992- 1 Bottlenose dolphin found trapped in Lake Goegrup, already freeze-branded 06,had to be put down due to horrific sun burns
Late April 1992 - Stillborn calf recovered from Dolphin Pool ( mother had carried it for several days)
5 December 1994- 4 bottlenose dolphins stranded on mudflats at Soldiers Cove , all males, and were freezebranded 12,13,14, and 15. These dolphins were released to deeper water from the old boat ramp, south of the old traffic bridge. All males.
Mid February 1995 - 1.85m female dolphin rescued from stranding on mudflats near Robert Bay in the Peel Inlet
10 December 1995- bottlenose dolphin freezebranded 12 was observed in a poor condition in Yunderup. This dolphin was captured and given a vet assessment, and a blood profile taken, then released. He was found dead on 23 December 1995 inside the Dawesville Cut, cause of death established by post mortem to be peritonitis.
8 November 1996- A dolphin stranded on the mudflats of Falcon for six or seven hours prior to being rescued. The adult 2.2metre bottlenose was struggling in water only 15cms deep. Although distressed, the dolphin was not sunburnt or hurt. The dolphin's condition was checked by a vet, before he was placed on an inflateable raft and towed to deeper water. This dolphin was not freezebranded.
13 March 1997- 6 bottlenose dolphins were trapped in Lake Goegrup, 2 adult females, 1 juvenile female, and 3 males. These dolphins were freezebranded 01 (a male rebranded from previous stranding), 17 (male), 20 (female), 21 (female calf), 22 (her mother), 23 (male). Number 23 carried an old brand, probably from the 1990 Lake Goegrup stranding which may have been 05.
29 Sept 97- A mother and her young calf were rescued from stranding in the shallows in the yunderup branch of the peel inlet. This is near Coopers mill. Canoeists found the pair about 10am in some distress. Together with a local resident they used sacks to successfully take the mother and calf out to deeper water. The mother in particular suffered bad burns to her back.
8 March 1998 - 3 adult dolphins were stranded in low water off Mandurah quays during the night. Two were able to be coaxed out to deeper water and safety. However, the third dolphin needed to be lifted by sling and caried out by rescuers as it was physically stranded, unable to move at all by itself. All dolphins reunited once they were in safer waters and swam off strongly. No sunburn was reported. The dolphin that was physically stranded had an old freezebranded number on its dorsal, the first letter being 0.
26 March 1998 - A dead dolphin was found in Mandurah's estuary waters. The dolphin had lost many of it's teeth and so was very old. It was not freezebranded and no visible signs of injury were observed. Measurements were taken, 2.57m in length, dorsal height 140mm, body width 635mm. It was presumed it had died from natural causes (old age)
30 March 1998 - Two dolphins were sighted stranded in Lake Goegrup, one physically unable to move on mudflats, the other swimming nearby in a deeper channel unable to escape due to the low tides. The stranded dolphin was freezebranded number 17, who has been stranded before. This dolphin had a series of cuts on its head, so regular it was thought they may have been injuries from a boat propeller. As well as these cuts, it also had an injury on it's tail, from the stranding. It was decided to place 17 on a sling and carry him to the deeper channel, to join the other dolphin. Though obviously exhausted and stressed from its stranding, this dolphin breached out of the water, once it was released and in safety. As the tides rose overnight, it was hoped both dolphins would then be able to navigate across, and out of Lake Goegrup safely. A search of Lake Goegrup and the Peel inlet the next day, revealed this plan had been successful, and number 17 was seen swimming strongly with a large pod of other dolphins.
19 April 1998 - A dolphin was seen pushing and carrying her dead (miscarried) calf on her snout, surrounded by a large pod of other dolphins in the Peel Inlet.
19 April 1998 22 has a new calf, (her next after 21) also another mother seen with newborn
30 May 1998 Nikky seen with newborn
15 July 1998 - A young calf was seen trailing prawn netting underneath it, and wrapped around its body, swimming with it's mother number 22. Initial efforts to catch the calf were unsuccessful and a full CALM response was planned for the next day. However, on finding the baby again the next morning, it was clear the calf had been able to escape the netting by itself overnight. This calf is now named FALLON.
18 August 1998 - An adult dead dolphin was washed up on San Remo beach. very badly decomposed. No identifying marks or features could be distinguished.
26 August 1998 - 2 whales were sighted off silver sands beach inshore, one appearing to be in trouble. Despite the second whales attempts to be guiding the other out to deeper water, one of the whales then beached alive. However, it died within an hour and obviously had been very sick. It was found to be an adult fin whale, approx 15m, 40 tonnes approx, possibly 30 yrs old, with no visible wounds other than scrapes from being tossed onto the rough sand repeatably in the rough shore waves. It had stood no chance of survival.
4th Oct 1998 A mother dolphin is seen with significant sunburn on her back from a stranding near coopers mill (she was with her calf)
Dec 1998 The dolphin now named Bendy Wendy seen with large sunburn wounds on either side of her dorsal. Must have been stranded
15 April 1999- A dead male calf was found washed up on the beach between Halls Head and Falcon. Only approx 4 months old, it probably died from starvation as it was very emancipated.
15 April 1999 2 newborns sighted born approx end of march
April/may 1999 another newborn seen
29th September 1999 – mother seen with tiny calf
15 October 1999 - A dead female 1.64m bottlenose dolphin was found washed up on a sandbed outside murray river entrance in the peel inlet. Cause of death unknown.
27 November 1999 - Decomposed dead adult dolphin found washed up on the beach at Falcon. Had most probably been caught in craypot ropes and drowned. Length 2.4m
10 February 2000 - Dead male bottlenose dolphin found decomposing on Madora Beach. May have been very old as it's teeth were almost completely worn down flat. Length 2.35m
2 very young calves, possibly stillborns found dead and badly decomposed south of white hills Dawesville. Lengths 1.m and 1.2m.
26 Febraury 2000 - Mother and calf pair found stranded in shallow water between the Serpentine and murray river entrances. People crabbing nearby were able to successfully assist the pair out to deeper safe waters.
1 May 2000 - Dead male bottlenose dolphin washed up on the beach 1/2km south of Avalon. Length 2.5m teeth quite flattened with age.
15 August 2000 - A female short finned pilot whale washed up dead alone at falcon beach, very decomposed. It was thought to be already dead by approximately 2 weeks. Length 4.1m. No teeth seen
2 December 2000 - A severely sunburnt dolphin was first noticed by Dolphin Encounters Mandurah. This dolphin must have been stranded and been able to eventually work itself free once the tide rose. It has later been established this was the male dolphin freeze branded with number 15 and his constant companion male freezebranded number 14 was also stranded and suffered burns. Both male dolphins are now recovered.
27th December 2000 - 3 beaked whales stranded in mandurah. One was found dead at Avalon. The other two were assisted by CALM, emergency rescue officers, the volunteer dolphin rescue group and many members of the public, out to sea. One of these whales later restranded at Secret Harbour and was then successfully rescued and taken far out to sea by boat beyond the reef. The total rescue efforts took nearly 10 1/2hrs. As neither whale was reported restranded or dead, it is considered that the two rescues were successful.
A dolphin with it's tail and body caught in craypot ropes in the ocean south of the Dawesville cut now owes its life to three mandurah residents who successfully cut it free.
24 June 2001 - A small male calf was found dead washed up on Seascape beach. Length 1.37m long. It is thought it may have run foul of heavy surf and the reef during a recent storm.

2nd August 2009 – Thanks go out to the many people who reported a calf in the Dawesville cut with a huge mass of fishing line and seaweed tangled on its body and tail, making it very difficult for the calf to swim.
We’re happy to report CALM immediately attended on Sunday 2th August and after a lengthy rescue effort was successful in removing the huge mass that was tangled round the calf including fishing line and many hooks.
Its fin is however very mangled from the fishing line cutting across it and the top third is nearly off.
Well done to CALM for a huge effort and their success. We do ask the public to continue to keep an eye on the calf and dolphins in general in Mandurah. And PLEASE remove any rubbish you may see in/around our waters.
Fishing line, plastics, ropes etc in particular! (THIS DOLPHIN IS STILL ALIVE AND WELL years later - resighted 1ST June 2012 in the channel with many others. Has lost the top third of its fin)
8th September 2009 -Dead Adult male dolphin found near Mandurah Quays. Was missing all its front teeth so was quite old.

9th November 2009 - A juvenile dolphin ( Christmas calf to Nicky was rescued from stranding in very shallow waters in cox bay. many thanks to everyone who assisted!
Weekend following the above stranding this rescued juvenile dolphin was reseen twice, back swimming alongside it’s mother (its mother Nicky
is the dolphin with only half a fin ) The rescued juvenile named Christmas has some sunburn on its back and can also be recognized by a nick out of the back of its dorsal fin about halfway down. A very successful rescue!
2010 NEWBORNS. – As far as I know there was 4 new calves born and still alive by the end of March amongst the main estuary/inlet dolphin pods. Of course there is probably more born further afield in Harvey estuary and Dawesville ocean.
one calf was born late December 2009 one born early January 2010, one born Feb 2010. One is reported to be born 3rd march in mandjar bay!
Mothers are dolphin with nick out of fin half way down, dolphin freezebranded 21, and one with no identifying marks on her dorsal. Another with very large unusual shape dorsal may also be a mum.
We believe a 5th newborn is now in the inlet as of 17th may 2010. On a sadder note the male dolphin with freezebrand 23 has not been seen for a long time. He would be in his older age possibly over 30yrs.
12th June 2010 - A dolphin is seen pushing her stillborn or dead newborn calf near the Mandurah marina. Dolphins mourn their dead and she is likely to stay with the body for several days. A smaller adult, she may be a first time mother and unfortunately there is a high mortality rate in first calves especially.
A sighting of a possible newborn has been reported approx 14th October keep your eye peeled! Also late October reports of a possible second newborn.
30th October 2010 Dead mature 2.7m dolphin found washed up dead on pyramids beach Dawesville.
3rd November 2010 – A juvenile dolphin was seen struggling to swim and breathe in the shallows of Fairbridge Bank. Unfortunately this extremely thin young male dolphin died. The body was retrieved and has been sent for necropsy ( liver)
2nd February 2011- There are now three calves in Mandurah waters. Born October, December and January approx the last one being only a few weeks old at the moment. Thanks to the cruiseboats for this info! The mums and calves are most often seen in the town waters including within mandjar bay so keep a look out for these cute youngsters and their families.
3rd February 2011- A young dolphin (approx 5ft) was rescued off a sandbar in Lake Geogrup today by the helicopter pilot and his crew member who do the mosquito spraying. They saw the dolphin well and truly stranded in the hot sun so landed their helicopter nearly and were able
to carry it to deeper water and saw it swim off. Well done Guys!
8th February 2011 – possibility of a 4th newborn now………….. and by march possibly 5 newborns
20th March 2011 – newborn female calf found dead on melros beach sent to Murdoch for necropsy 1.1m long
April 2011 another newborn sighted in the peel inlet now possibly up to 6 ( or more) in main estuary/peel inlet waters
One of the dolphin calves ( Beaky) appears to have a badly asymmetrical jaw (top and bottom jaw doesn’t meet together as normally would, bottom jaw appears to be protruding up at the end with the top jaw at an abnormal angle over it)

10th April 2012 dolphin with scoliosis sighted in the inlet quite possibly Blacky!
21st April 2012 New newborn calf seen in the inlet ( now at least 5 live calves this year) mum has distinctive rectangular notch out of her dorsal
3rd May 2012 – A mother and calf pair of spotted dolphins stranded along seascapes beach. Both unfortunately died. Bodies taken to perth zoo for necropsy. The mother was found to be very sick and would not have survived, she also was not producing milk for her calf.
Thanks to those that attended, especially for bringing the calf and mother to be together for their final moments. Findings were that they probably died both from starvation. It is unusual to see spotted dolphins in our waters.
30th May 2012 Mandurah cruise staff saw the large male dolphin freezebranded 01 with wounds from an attempted shark bite – wounds from the teeth on its side and larger wound underneath its body today. Despite these wounds 01 was seen swimming fine with nicky and others in the canals. Dolphins have remarkable abilities to heal. Many thanks to Mandurah cruises for the information and Hayley for the photos. Dolphins in other areas have survived larger shark bites (eg many at shark bay bear scars). He is very large older male.so pretty tough!
01 has been seen feeding in the inlet with other dolphins, recovering
15th June 2012 Mandurah cruises see a possible new baby in town waters ( 6 at least)
13th July 2012 01 seems healed after the attempted shark bite – looking good and swimming with his male alliance buddies
13th July 2012 – another smaller dolphin seen with teeth wounds from an attempted shark bite. This dolphin should heal just as 01 did. This dolphin has been seen several times since playing and fishing.
16th August 2012 A new baby calf seen in inlet (now 7 at least) very late to be born this year
20th August 2012 Dead male dolphin ( Captain Morgan) 2.6m found in Harvey estuary shallows near meelup point. Half its top teeth were completely worn flat and others missing indicating it was quite old.
8th October 2012. Old oceangoing male dolphin ( Jagger) found dead by professional fisherman in the Harvey Estuary, south of the cut (had shark bite wounds, suspected bitten in ocean later died in estuary). That dolphin has been seen previously swimming out to the ocean via the cut.
10th October 2012 Mandurah cruises report a dolphin seen in town waters with severe sunburn across its back (from stranding). I believe it is Nickys
2nd last calf called Christmas.
26th October they report it is doing well still shows burns but they seem to be healing. Later in the year this dolphin is seen again several times healing very well. (seen completely healed with very little scarring March 2013)
20th October 2012 – dead female dolphin 2.2m long found washed up in shallows approx halfway down Harvey estuary birchmont area. Many thanks to murray shire ranger who attended!

24th December 2012 Blacky (dolphin born with twisted spine (scoliosis) seen again in the peel inlet.
25th December 2012 Severely sunburnt dolphin ( Scarry) seen in the inlet must have stranded in hot sun and not been seen by anyone…dolphins do possess amazing healing abilities so should survive (seen healed 19th March!)
This dolphin was kept under monitoring as much as possible and has been seen several times swimming well and actively feeding with others (see 19th march below)
24th Dec- 31st Dec 2012 Blacky now moving very slowly and doijng poorly (during extreme heatwave). As much as possible its movements were monitored & kept safe from main boat traffic when possible. Wildlife officers and vet attended.
