Fish

Cuttlefish are in potential danger if the BHP desalination plant goes ahead in the Spencer Gulf. The video below is from ABC’s Catalyst program & gives insight into why the BHP desalination plant may affect Cuttlefish numbers, and, in time may even lead to their extinction.

Point Lowly, at the top of Spencer Gulf is a Cuttlefish breeding area. The extra salt pumped back into the gulf will result in higher levels of salinity, which affects growth and mortality of the Cuttlefish eggs. BHP have said that they have taken this into account. However, Oceanographer Associate Professor Jochen Kaempf has stated that the ‘dodge tide’ which happens 3-5 times a month has the ability to stir up & move the toxic sludge resulting from salt dumping further into the Cuttlefish breeding environment.

These are highly intelligent, unique and amazing creatures that need to be protected, so please watch the video & if you would like to find out more about the desalination plant, download the BHP report below.

Cow fish

The cow fish is a type of boxfish and are quite rigid. They are generally found on rocky reefs. We have about  20 species in Australia.

Fish are sometimes stranded alive in pools on outgoing tides, but usually they are dead, and a rare feast for seabirds. You might occasionally also find freshwater species on metropolitan beaches following rains that have washed fish, such as European carp, out of the Torrens.

Porcupine fish

Porcupine fish (a.k.a. balloon fish, puffer fish) Diodon sp

Best not to step on a dead, dried porcupine fish! It has nasty, long sharp spines. In a live fish the spines provide defence against predators, as does its ability to inflate its body, making the spines stick out – like an echidna in defensive mode. These fish are not built for speed.

 

 

 

Toad Fish Tetractenos

Toadfish – don’t eat!

These fish grow to about 15 cm (this one was about full size) and are common in shallow water in southern Australia. Like other members of this family, toadies are poisonous.

 

 

 

 

 

Short-headed Lamprey (a.k.a. Australian Lamprey) Mordacia mordax

Lamprey

Looking like an eel, these fish grow to about 50cm in length and move from marine to fresh water to breed. In the sea they parasitise other fish. Most fish have jaws, but Lampreys are blood sucking and have a round funnel-like mouth with many small sharp teeth.

 We continue our conversation with featured speaker Sarah-Jo Lobwein about the work she does regarding single use plastics #swapforthesea . What has been your favourite or most impactful achievement to date? . “When another local venue or business in my local council area contacts us to work with them or to promote that they have embraced plastic-free alternatives, they add to the growing tide of change happening locally and globally. . This then adds more support, influence and encouragement for more businesses and individuals to become aware and change their behaviours. . Personally, working with the next generations also has a great personal, local and global impact. Children are amazed and shocked when they find out what items consist of plastic (such as chewing gum) or why a product cannot be recycled, or why an animal has died from plastic pollution. . They innocently yet intelligently ask “why” we use single use plastics and why companies use ‘hidden’ plastics without public notification and think of easy solutions rather than making excuses to keep polluting. . They still go and purchase an ice cream wrapped in plastic packaging, but the seed is planted in their thoughts, and it is not their responsibility that the packaging is harmful; it is the brand’s responsibility to be providing a sustainable option.” . To our #FoGSV Community, what impact can you have? Think of the ripple effect, your action can and will have an onflow affect. You can influence family, friends, your work and local businesses just by being an inspiration in your own circle of influence. . . . . . . #waronwaste #waste #saynotoplastics #refuse #recycle #reuse #repurpose #upcycle #protectourgulf #saveouroceans #gogreen #nature #conservation #climateaction #marinedebris #beachcleanup #bethechange #adelaide #fogsv #friendsofgulfstvincent
 . Following on from our first instalment, we hear more on Sarah-Jo’s presentation and look out at the end, you may be shocked! . Please provide a brief overview of your talk topic: . “Sea Change - Local plastic pollution, marine conservation and Community Empowerment through Education, Awareness, and Action to change attitudes and practices and  #SWAPFORTHESEA - empowering the community and individuals to change their behaviour by discussing and embracing simple everyday, sustainable swaps that are easy to do, and will drastically reduce your plastic consumption while maintaining a ‘convenient’ lifestyle! . Immiscible - why water and plastics do not mix - simple solutions to avoid single use plastic pollution to Stop the sea drowning in plastic - Global pollution, Global solution - raising the awareness of contributing countries, communities and individuals. . Simple plastic-free alternatives and choices to follow without changing our convenient lifestyles at home and while travelling the seven seas, which will have a huge positive effect for the ocean, the flora and fauna and ultimately ourselves! An engaging look at a serious problem including the ‘hidden’ plastics we use (did you know most chewing gum is made of plastic?), the effects on marine life and humans, and easy preventative actions for individuals.” . Did you know about the chewing gum?  . . . . . . #waronwaste #waste #saynotoplastics #refuse #recycle #reuse #repurpose #upcycle #protectourgulf #saveouroceans #gogreen #nature #conservation #climateaction #marinedebris #beachcleanup #bethechange #adelaide #fogsv #friendsofgulfstvincent
