Shellfish reefs (oysters, mussels etc.) are “the lungs” of healthy estuaries, providing various “ecosystem engineering” services including filtering to clean the water, nutrient uptake, shoreline stabilisation and food and shelter for fish and crabs.
However, today less than 5% of historical shellfish populations remain in Pumicestone Passage, due mainly to declining water quality which disrupts their breeding cycle. Pumicestone Passage is under severe stress and intervention is needed to try to prevent further decline.
Young fish up to about a foot long are covered with round, black spots and were formerly thought to be a distinct species (called willow cats, lady cats, squealers, or fiddlers).
Intertidal oyster clumps at Ningi Ck in Pumicestone passage undermined and degrading into the mud due to recruitment failure.
As it stands, roughly 83,000 tons (75,000 metric tons) of fish and other ocean life are lost to the Chesapeake Bay dead zone each year—enough to feed half the commercial crab catch for a year.

Loss of subtidal shellfish reefs results in lost fisheries production and nutrient assimilation capacity which then causes other undesirable ecological outcomes such as declining stocks of fish and crabs, and turbid water which reduces survival of seagrasses. This video from the USA highlights the various reasons why we have lost oyster reefs in Moreton Bay, and why we need them back.
- Of the catchment area should be studied to determine how they might contribute to or interfere with the farming enterprise. This chapter addresses the questions of selecting good pond sites (Section 1.1), integrating fish culture into the farm as a whole (Section 1.2), and marketing the fish that have been produced (Section 1.3).
- Changes in the amount of salinity will determine which fish can live in the area. Species found in these waters include redfish, sea trout, snook and striped bass. Some fish live in saltwater, but swim up streams and rivers to spawn (lay their eggs).
Nutrient loading and excessive sedimentation have choked subtidal shellfish reefs in Pumicestone Passage and Moreton Bay. Intervention is needed if these lost ecosystems are to be restored to regain biodiversity and fish numbers.
Our goal is to scientifically examine the best methods of restoring subtidal shellfish reefs in Pumicestone Passage and quantitate their effects on improving water quality and fish habitat in the Passage and Moreton Bay. Trial shellfish reef modules were deployed into Pumicestone Passage on 12th December 2017 – for more information see our Map and Research Priorities pages. Results to date have been very encouraging, including a doubling of fish numbers in the first 6 months, and after 30 months we generated over 10 times the number of fish with nearly 4 times the biodiversity compared to pre-installation surveys. Videos show increased fish activity over patch reefs, crate reefs and BESE reef modules compared to non-restored areas. Additional trial patch reefs were deployed with improved fence modulesinstalled in December 2018 to examine if improvements to the original designs are possible. Transects after 8 weeks and invertebrate surveys after 3 months, 6 months, 9 months and 12 months suggest the new trial reefs are securely located and establishing healthy invertebrate populations which include a several species of rock oysters. Our results have mirrored those of successful shellfish restoration trials done overseas with high survival (>75%) and up to 10 baby oysters settling on a single recycled oyster shell after 24 months deployment
Results of restoration trials after 18 months are promising, with high survival and up to 10 baby oysters settling on each recycled oyster shell placed in Pumicestone Passage.
Short videos of the 3 month old reefs found that fish populations associating with the reefs include whiptails, silver biddies, stripeys, grass tuskfish, blacksaddle goatfish, fan bellied leatherjackets, Gunther’s wrasse, happy moments, moses perch, tarwhine, yellowfin bream, crested morwong, Mullers coralfish, several species of cardinalfish and a juvenile tawny nurse shark. June 2019 fish surveys (done 6 months after the 2018 deployment and 18 months after the 2017 deployment) found that fish species richness had increased further to be 82% higher at the reef restoration site compared to control sites. Similarly, despite heavy fishing effort, harvestable fish abundance had increased to be 128% higher on the reef restoration site compared to control sites, and total fish abundance had increased to 268% higher on the reef restoration site compared to control sites. June 2020 fish surveys (30 months after the 2017 deployment) found species richness continued to increase to over 380% compared to baselines while harvestable fish species increased by 1640% (total number of all fish species increased by 1070%). To help protect the trial shellfish reefs from damage, we ask that water users do not anchor in the trial area, as this can cause damage to the 2017 deployment patch reefs in particular, as shown in this underwater drone video.

This is one of several similar projects that have started recently in Australia, for more details on the national situation, see www.shellfishrestoration.org.au or follow the Australian Shellfish Reef Restoration Network at https://twitter.com/ShellfishReefs. For more background information on our local project read the National Environmental Science Program report on shellfish reefs in Southern Queensland HERE, and view the presentation by Dr Ben Diggles presented on World Oceans Day at Bribie Island Library on 30 May 2019. Some earlier media on our project can be found on Radio, TV and in newspapers.

Shellfish are “ecosystem engineers” that work tirelessly to maintain the health of our estuaries
Most played games
The world of wild nature is cruel and harsh. If you can’t take over your opponent, prepare to die. That’s the law of the jungle and it works underwater as well. You can make sure of it by trying to survive in the merciless environment of a new IO game called Feed and Grow. The point of the gameplay is rather simple: move around a virtual space filled with other fishes, scout for food and eliminate your rivals to become the biggest and most dangerous fish in the sea! This is going to be thrilling!
Feed And Grow Fish Map Areas
In the depth of the ocean
So, you are going to find yourself in a spectacular underwater environment precisely copying the actual marine landscapes you can see somewhere at the Great Barrier Reef. The graphics are performed at a high level and you will get the greatest impressions from finding your way around this colorful 3D world. However, don’t spend too much time admiring the views: danger awaits you at every corner. The location is packed with other fishes controlled by players just like you. They, too, want to prevail on the map, so you can expect constant attacks on your gilled charge. As long as you are still a small fish and can’t hope to win in an open combat, it makes sense to stay away from those stronger than you. However, the balance of power can always change in your favor if you succeed in collecting edible supplies scattered around. Each type of food will bring you a certain amount of experience points. Once you earn enough points to upgrade your level, your stats will increase. That will affect your damage level, health and other parameters crucial for surviving in the open sea.
Kill or be killed
It would be way too easy to just swim around gathering delicious corals and beautiful shells. And way too boring. So the game developers included an element of danger by introducing multiple opponents that you are going to fight literally every other minute of the gameplay. You will see them around you all the time. Some of the fishes will try and attack you and it’s up to you to decide whether to run for your life or take the challenge. Of course, it’s much wiser to avoid confrontation with big fishes and chase little ones. Killing a fish will give you an instant increase in experience depending on its size and level – after all, it must be much more nutritious than any of the food you can find around. So, it’s as simple as that – kill or be killed.
Playing this way, hour after hour, you can grow your scaled companion to an unlimited size. It can become a notorious killer everyone is afraid of. But even the biggest fish can lose a battle. If you happen to die, don’t worry – you will be able to respawn in a couple of seconds. And then you can start all over again, more experienced and dangerous than ever… Amazing graphics, fascinating gameplay and plenty of missions you will have to accomplish for valuable rewards will keep you glued to your computer screen!
