Final Update for 2010

WE’ve come to the end of another fantastic year on the sardine run (so far as UKZN sardine run research field trips are concerned). Thankfully, the sardine run is happening along the Durban shoreline, even now as I type. You gotta love this time of year. Please see below for the final update of our 2010 research:

Final Update for 2010

Thanks to all of you who followed and commented upon our work.

all the best and till 2011…


HI Blogees,

sorry about the lack of postings lately; my laptop died in PSJ, and it’s not the sort of town to be fixing laptops in.

We’re back in Durban after successfuly deploying our 3rd tag. I will do a proper upcatching when I finish ploughing through my emails and stuff.

The sardines are on the KZN coast with netting happening for the past 3 days. This strong westerly will have put the brakes on for a while, but with good weather predicted for the weekend, one should get one’s butt down to the KZN South Coast for a good chance of sardine activity. Baizley is a good bet.

more later,

A Timely Day Off

The westerly has arrived. We launched at our usual time this morning and there was about 15 knots of wind on the water. This is an uncomfortabl wind, but by no means a boat slayer. However, there is another big buster on the way, and we don’t want to have our last tag committed and find ourselves in a nasty sea. So we turned around and came home to toasted sangers for breakfast. This afternoon will be devoted to chopping up our fish samples etc. etc. Tonight is the big final, and all of the sardine run boat crews will head somewhere festive. Good times indeed.

SO, where are the sardines?

Well, we know that they are up on the Upper Wild Coast, and we know that conditions are cooling down along the east coast, which gives the sardine and excellent chance of making it up to KZN, so where are they? Reports that we’ve had are that the fish are around, but that they are quite deep. This means that the fish cannot have been close to shore over the past couple of days.

Who doesn't love to see cows on the beach?

Since my last blog, we had a westerly buster blast through the coastline. These winds are thought (by many old hands of the run) to help the fish move up the coastline, which should be a good thing. Unfortunately, strong westerly winds are often accompanied by large swells, which, our data show, tend to result in fewer sardine sightings from shore. Perhaps the large swell drive the fish away from shore and into deeper water. We’re hoping that this nice little spell of good, settled weather and cool sea conditions (19 – 20 degress C) that we’re enjoying, will help with the sighting of fish from land.

The problem with cool sea conditions is that if they stretch out across the continental shelf, then the fish will be able to inhabit the whole shelf and needn’t run the gauntlet of the near shore. Ideally, we’d now like to see some warm water press them up tight against the shoreline, so that we can get the spectacle that we crave. It would not be unheard of for the fish suddenly to appear off the Mdoni region having not been sighted further south along the KZN coastline. In the Mdoni region, sardine are likely to run into the warm Durban Eddy, a semi-permanent gyre of the Agulhas Current that flows shoreward at Mdoni and then northward past Durban. Our data show that it is in this region of the coastline that the sardines come closest to the shoreline. This obviously makes for good sight-seeing from land, but also is very useful for the beach-seine netters who are, undoubtedly, all poised for their annual harvest. Tomorrow morning we head back down to PSJ to have a second stab at collecting our data. I’ll be sure to keep everybody posted as to our progress (and will once again have to wrestle with the jaw-grindingly slow internet connection). Gotta love the Transkei. I guess it’s rad that the internet even reaches down to there.

Packing the boat in preparation for our next day on the water

All the best…
