J. PISCICULTURE AND THE FISHERIES. 399 



We have no association precisely similar to this in the 

 United States, although the harmonious co-operation of the 

 Fishery Commissioners of the several states of the Union, 

 which has been so frequently exhibited, perhaps answers the 

 purpose to a certain degree. We have, however, nothing in 

 the way of official reports in America that at all correspond 

 in thoroughness and extent to those of the German associa- 

 tion documents emanating from the Department of Fisheries 

 in Canada coming nearest to them. In view of the fact that 

 the United States has so vast interests in this direction, cov- 

 ering such an extended field of operations, with so great a 

 variety of resources, Ave trust that some similar effort may 

 be made to give completeness and thoroughness to the in- 

 quiries connected with this subject. Circular. 



FISHERIES OF THE GULF OF NAPLES. 



An important addition has been made to the list of works 

 devoted to inquiries and instructions in regard to the great 

 fisheries, in the form of a paper by Mr. Achille Costa upon the 

 fisheries of the Gulf of Naples, published by the Royal Insti- 

 tute for the Encouragement of Natural Science, etc., of Naples. 

 The subject is treated under four heads : first, a description 

 of the various modes by which fishing is prosecuted in the 

 Gulf of Naples, whether commendable or otherwise, with en- 

 gravings of the nets and other apparatus used ; second, the 

 consideration of the various modes of fishing, and their rela- 

 tionship to the present and prospective supply; third, mem- 

 oranda in regard to the localities in which the different kinds 

 offish and other marine animals are to be found, and the fa- 

 vorite places for depositing their spawn ; and, fourth, a sys- 

 tematic catalogue of the different species of marine animals 

 found in the Gulf of Naples, and gathered for the purpose of 

 serving as food. Atti R. I. cVincorragiamento Scienze JSTatu-

FRENCH FISH-BREEDING ESTABLISHMENT. 



It is well known to many of our readers that the French 

 government erected a very extensive establishment at Hunin- 

 gen, on the Rhine, for the purpose of collecting and hatching 

 eggs of various choice varieties offish, to be used in stocking 

 the rivers and lakes of the country. This has passed, by the
