BCSS Underwater Observatory Project: predator kill behavior

BCSS, WildBlue Expeditions, and MYDO fishing are collaborating on fish attack behaviour studies.

BCSS Underwater Observatory Project: predator kill behavior

BCSS Underwater Obervatory Project: The first ‘croc couta comes in for a real close look but turns away right the last second. There are two of the +-20kg class fish circling the live bait with piqued interest. In a flash the hapless bonito has its tail sliced off. Blood streams out. Another fish circles and bang! The couta comes from in from below and chomps into the bait. Vas! But somehow he misses the hooks and another guy comes in and finishes off.

This action is all part of the Bazaruto Centre for Scientific Studies’ (BCSS) Dr. Mario Lebrato’s long-term ocean observatory project. One of only a handful worldwide, Dr. Lebrato is set to deploy a multifaceted underwater monitoring system. Cameras, sensors and a myriad of other sampling equipment will be installed all over the Bazaruto Archipelago. For long-term data recording and analysis.

Luckily, part of these underwater observations includes predator fish kill behavior. Trolling tow cams on marlin dredges and teasers, and right in front of live baits, is opening a huge new three dimensional perspective of a mostly viewed in 2D wake and prop wash. What goes on down there is gob-smacking. So many fish come in interested, but then shy away at the last minute, and move on. In fact, the plentiful and ever-present Zambezi shark is far more careful than the aggressive king mackerel. Tuna seem to be the most suspicious so far. Cobia are also wily characters. Talang queenfish get super excited about a live bait, but will not touch it! Then it grabs a lure! Amazing revelations about fish learning and behaviour.

Wait ’til you see the Zambies following the boat!!!

The hours and hours of material recorded will go back to Europe for careful analysis and processing into data.

Watch this space!

For more action from deep down off Bazaruto and surrounding waters, by BCSS, WildBlue Expeditions and MYDO Fishing, stay tuned!

Saving the Seas: Marine Reserves are the only way

Marine Reserves are the only way out of this mess

Saving the Seas: Marine Reserves are the only way

Marine Reserves: Dr. Callum Roberts even features in this classic Attenborough style documentary, by National Geographic (written and presented by Joanna Sarsby), called…

Deep Trouble“.

The script follows Dr. Roberts’ comprehensive summation of the state of our oceans, in well…”The Unnatural History of the Sea”. A thoroughly disturbing, but very well presented book, that Roberts’ takes us through history with. Back to when there was 100% of the ocean life still living. And traces the demise of our marine fauna and flora, through the ages, and into our current technological and destructive fishing practices.

You can watch the whole documentary below, or click this link – https://youtu.be/gmt_eRXBZrw?t=2549 – to get straight to the point, in the movie, of what we can do to save our ocean and it’s residents.

Facebook itself has shown to be a great platform where you can air your views and concerns, and assemble people into more unified collections. This impetus can be channeled into momentum and public voice.

As our new president and team ( and hopefully whole new government soon one day), have to pick up the pieces of wanton destruction caused by Zuma and his cronies and their fiscal shenanigans, perhaps it’s time to start putting real pressure on the decision and policymakers. For Marine Reserves. And to bring back the highly qualified Ezimvelo. The decision to hand over the thankless and huge task that Ezimvelo was doing so well (the policing and maintaining order on our shores), to the totally inexperienced and non-cohesive DAFF officials, was a government level budget decision, as the coffers were being emptied so very effectively by the government.

AT the moment, it is literally a free-for-all as the DAFF crew just don’t seem to be able to find purchase with their new task at all. Many places have not even seen an official since Ezimvelo were fired. Without reason. All those years experience now totally wasted.

So even though we have the semblance of a Marine Reserve ideology and policy and have a few dotted up and down our vast coastline – without effective policing, what good are they?

Bring back Ezimvelo! Give us more Marine Reserves!

The great KZN nurdle disaster

The nurdles came from off of this ship

The great KZN nurdle disaster

Cameron Johnstone the admin of Salt Fishing South Africa group on Facebook has compiled an excellent report on the great KZN nurdle disaster, which occurred recently.

MSC Shipping are squarely in the spotlight as they allowed this ecological tragedy to unfold unchecked. The nurdles, which are little plastic beads heading for industry, spilled out into the Durban harbour entrance, as the MSC ship ran aground in inclement weather. The ship was saved but when it drove into the harbour, it crashed into another ship, and the containers carrying the nurdles ruptured as they tumbled off the MSC ship and into the water. Literally nothing was done by MSC or port authorities or anyone, to curb the spill.

This has happened before elsewhere in the world, costing millions in clean-up operations. Here in Durban, the powers that be, and the perpetrators, simply do nothing. For days after the incident, the nurdles were allowed to spill out unchecked. As many as three containers full hit the water. Allegedly only one was recovered, and no-one is forthcoming with information at all.

Cameron’s report is detailed and accurate. In a spate of admirable investigative journalism, Cameron and friends uncovered the series of still photos, illustrating the incident in full colour. He deserves any support or assistance he can get. Right now the nurdles have spread up and down the KZN coast, into the Transkei, and even further way down deep into Cape waters.

Cameron and his efforts have resulted a cleanup operation to remove as many nurdles as possible, from the environment right now. This is where you can help. At this relatively early stage, we can hopefully make a difference in the overall percentage of nurdles spilled out into the ocean. They do float so – head on down to your local beach and start collecting! Keep them. Follow Cameron’s group for further instructions.

The harm that nurdles can do, aside from the obvious as in fish eating them, can be found in detail, in Cameron’s report at the link below:

Catching Garrick on fly with JP Bartholomew

Catching Garrick on fly with JP Bartholomew

I’ve often  wondered why I have this obsession for catching Garrick on fly, maybe it’s those heart stopping chases and the fight as they they try to smash your fly on the surface which play a major role in driving up my adrenaline levels.
Throughout the year I spent My time chasing Kingfish,Snoek and other Game fish, but come May when the first Garrick start arriving  with the Shad- and hopefully the annual Sardine Run – we all get excited.
Garrick are found right around our South African coastline, in summer they prefer the cooler Cape water’s ,but in winter the arrive on our doorstep in KwaZulu-Natal ,and stay here until they spawn in spring before undertaking the long haul back to the Eastern Cape in summer.
They prefer sea temperature’s between 17’C and 23’C and they are able  to tolerate water’s with low salinity levels like Estuaries where they spawn.

The ‘Big Cleanup’ this International Coastal Cleanup Day marks one year to World Cleanup Day 2018

World Cleanup Day 2018

The ‘Big Cleanup’ this International Coastal Cleanup Day marks one year to World Cleanup Day 2018

Let’s Do It! Africa have the following cleanup initiative coming right up…

Covering nearly 1,500 kilometres of the South African coastline, with a number of nodal cleanups to be implemented from Melkbosstrand in the west, to Ballito on the east coast of South Africa, the inaugural ‘Big Cleanup’ – a network of participating organisations and volunteer groups – will deliver a wave of change to our shores this International Coastal Cleanup Day (ICC),September 16th, and all members of the public are invited to join in on the action.

The WESSA Tourism Blue Flag project – a three-year coastal tourism and youth development project implemented by WESSA in partnership with the National Department of Tourism – along with the Let’s Do It! Africa waste awareness campaign and other participating partners will run or support a total of 22 registered coastal cleanup events.  This collaborative effort will enjoy the official support of Plastics|SA as an implementer and main sponsor of the annual ICC event.

The International Coastal Cleanup initiative has been an unwavering platform to raise awareness on marine pollution, inadequate waste management, the need for recycling and non-littering in South Africa for the past 20 years.  This year’s ‘Big Cleanup’ network will enable citizens to actively do something to improve the health of their local marine resources.

Building on this model, the Let’s Do It! civic-led mass movement, currently being introduced to the African continent and neighbouring nations, works to unite the global community and encourages civic society members to stand up against the ever-growing trash problem by cleaning up waste both along the coast and inland. To date, 113 countries and over 16 million people have joined the campaign to clean up illegal waste.

Coinciding with ICC in 2018, an estimated 150 countries and 5% of the global population will participate in the long anticipated World Cleanup Day on 15 September 2018, making it the biggest positive civic action the world has ever seen.

Whilst global preparations are underway for the 2018 cleanup event, the Let’s Do It! campaign works to improve waste management in areas where waste is being lost to the environment, raise awareness about the issue, increase the frequency of citizen cleanups and raise future ‘waste warriors’ such as the youth employed as the Beach Stewards on the WESSA Tourism Blue Flag Programme, as proud coastal conservation ambassadors.

Other network partner organisations include: Two Oceans Aquarium; the Southern African Foundation for the Conservation of Coastal Birds (SANCCOB); Junior Chamber International (JCI) South Africa; Cape Town Environmental Education Trust (CTEET); the Sustainable Seas Trust (SST); Boaz Ocean Awareness Yacht; the Coastal Cleanup Convention; Nature’s Valley Trust; and White Shark Ventures.

The network also enjoys the volunteer support of The City of Cape Town; Ray Nkonyeni Municipality; Knysna Municipality; and Overstrand Municipality.

Special environmental calendar days come and go, but the sustainability of the ICC and World Cleanup Day models serve as a strong indicator of what citizens desire – a clean and healthy, waste-free planet.
