Pompanos as companions




This summer, never was I lonely on the shallow dives. The minute I jumped in the water 3 beautiful Pompanos(Trachinotus ovatus, Litsa, Mavrolitsa or Gofari in Greek) appeared immediately and were our loyal followers throughout the dive. They swim very fast, in a most elegant fashion and their curiosity is high, coming very close to swimmers without fear.
Their tail is fork shaped as is typical of the carangids, with a black spot on the tip of the caudal, dorsal and anal fins. They also have 3 - 5 dark spots on the front end of their body. The biggest specimen recorded was measured at 70 cm, although most commonly at 35 cm. Its distribution has been recorded from the Eastern Atlantic, Bay of Biscay, British and Scandinavian waters (rare) to Angola, including the Mediterranean Sea and offshore islands.
They usually swim in small schools near the coast in shallow waters, over sandy or muddy bottoms, unlike their other relatives of the amazing family Carangidae, which are mostly pelagic. They mostly prefer to eat small crustaceans, mollusks and fishes.
For this reason they are easy to spot and photograph.
Pompanos have a high salinity tolerance and are in the process of being farmed in China although they have a low food conversion rate, with trials being made to grow them using soyabean and fishmeal.

the wonderful Jacks!!!!!! their education and the perfect crime.





-One day i saw big great amberjacks in the Crete aquarium. I was with a friend of mine who was working there and as two amberjacks (of about 2okgr each one) approached us, she said to me "look at them their so gossipy fish!! i can't stand them, I feel like all the time they are talking about what I'm doing". It was true! They were looking like whispering to their "ears". So I laughed and started playing with the curious fish.
-Then one day as I was snorkeling for some photos in Chios I found them. The same reaction from the fishes. They come around me whispering to each other all the time. Nice opportunity for some photos I thought and I started flashing (photos 1 and 2).
-I showed the photos to another friend who likes spearfishing and he told me "Unfair fishes ! I've met them so many times and always,when they saw the spear they swam away without approaching me.". I'm lucky I thought, but everytime I meet amberjacks they come close to me and everytime George meets them,they run away!

A kiss in the dreamhouse


-Coris julis (Linnaeus, 1758) http://fishbase.org/summary/Speciessummary.php?id=58
-This colour combination is used by females. The males are more colourful.
-Fishermen consider them as bad luck because they are very hard to get off the hook.
-Mediterranean rainbow wrasse is most common name.
-Protogynous.
-I think that they make signs of alert by raising their first dorsal spine when a diver gets close to them.
-Γύλος το πιο διαδεδομένο όνομα του.

-Pseudocarnanx dentex (Bloch & Schneider, 1801) http://fishbase.org/summary/Speciessummary.php?id=1002
-Κοκάλι το πιο διαδεδομένο κοινό του όνομα.
-Very curious fish. If you are calm it will aproach you.
-When it is young it mimes other fishes. Generally has very strange behavior .
-Both photos taken from Paros island (mikri Santa Maria beach) at summer of 2008.
