240 SEA FISHERIES 



many kinds of fish mullet, sardines, mackerel, eels, 

 "surmullet," bream, sand-eels, &c. 



The bordigues (crawls) are " parks " or labyrinths made 

 of wickerwork or wattled reeds. They are placed in the 

 channels connecting the fishponds of the coast with the 

 sea ; at Les Martigues, Port-de-Bouc, Aigues-Mortes, &c. 

 The largest in use is nearly 1,000 feet long and 330 feet 

 wide. Madragues are widely used in the Mediterranean, 

 along the coasts of Provence, Algeria, and Tunis, in 

 10 to 16 fathoms of water. A madrague, or tunny-net, 

 is theoretically a series of chambers of network attached 

 to stakes. One of these chambers is open to the sea at 

 the end of a long barrier of nets known as the tail (coda 

 or queue). The tail stops the fish and shepherds them to 

 the opening. Once they have entered the first chamber 

 they find their way into- the others and crowd together in 

 the last the " chamber of death," or corpo. There they 

 are killed with clubs and harpoons and the bodies 

 removed by means of the latter. The series of chambers 

 measures about 1,000 feet long and 230 feet wide. The 

 tail is nearly a mile in length. The most important 

 madragues, or tunny fisheries, of this description are 

 those of Sidi-Daoud at Cap Bon, of Monastir and Kuriat 

 to the south of Susa, and of Bordj-Khadidja to the 

 south of Madhia. These take tunny almost exclusively. 

 Around Marseilles there are numbers of madragues the 

 madrague of Vilon, of Gignac, and of Niolon which 

 catch tunny, bonito, mackerel, bream, and sardines. 



The third and last class of devices includes the sardine- 

 nets of the Atlantic coast and all arrangements of hand- 

 lines and fixed or buoyed lines which before capturing 

 the fish attract them by some kind of bait. 



The sardine-nets which are used from Camaret to 

 Biarritz are drift-nets, similar to the herring-nets. They
