THE FISHERIES OF THE ADRIATIC, 



the subject of four reports, 1 which may be recommended to the attention of 

 those whom the subject may specially interest. Suffice it here briefly to 

 recapitulate the principal conclusions. 



i. The greatest influx of sweet water in the Adriatic is found on the 

 Austro- Italian coast between Grado and Ravenna. 



2. A current of sweet water flows from the north-west basin towards 

 south-east; the further it proceeds south, the nearer it skirts the Italian 

 shores, and the more it affects the deeper layers of water, thus bringing them 

 into circulation. 



3. A line drawn from Trieste to a point 20 miles south of Cape Pro- 

 montore (the apex of the Istrian triangle) gives a uniform depth of 

 20-22 fathoms. 



4. Increase of temperature towards the south-east ; in the north higher 

 temperature outwards, and in the south higher temperature nearer the shore 

 (thus showing the influence of the proximity of the land). 



5. Between Brindisi and Aulona the greatest depth is 270 fathoms (512 

 metres), and the ground temperature 14 centigrade (ii 0- 2 Reaumur). This 

 temperature is not lower than, shortly before, on the same line nearer 

 Brindisi, in 61 fathoms. The summer temperature of the water off Punta 

 d'Ostro, in 100 fathoms, is i3 0, 4 cent.; Ancona — Tremiti, J 3 and 60 fathoms, 

 13 0, 2-I3°'4 cent. ; Ouarnerolo, 40-50 fathoms, i3° - i i2°7 13°t cent. The 

 greater coolness of the water in the Ouarnero is due to the influence of the 

 ground-springs. 



6. Lower temperature and higher degree of saltness on the eastern than 

 on the western coast ; increase of temperature the more one proceeds south. 



7. In the Dalmatian channels lower degree of saltness and higher tem- 

 perature in the upper layers than on the Albanian coast/ 



8. The Gulf of Fiume, the Semia Channel, and the Ouarnerolo show the 

 lowest temperature of water in the whole northern basin of the Adriatic, 

 which fact is probably due to the abundance of fresh-water springs bursting
