IGO KEPOKT OF COMMISSIONER OF FISH AND FISHERIES. 



The Mackerel (Sromhrr scomhriis). 



Mr. Edwards ((.iitiiiiicd at Woods IIoll, in 1800, liis experiments with 

 n'pu-d to tlio liatcliin;^ of this S[)e<'ics whicli liad bt'cn conducted dur- 

 inj;- \s>iV>, ISSS, and 1S,S!>. From 7()S,000 eggs, (),SS,000 embryos were 

 obtaine«l. About 2,000,000 eggs taken from lish whicli had been dead 

 a sliort time i)roved worthk'ss. During November, 1800, small mack- 

 erel, measuring from 8 to 11 inches long, were unusually abundant in 

 Woods IIoll harbor, and about 5,000 were caught with hook and line 

 from the Fish Commission wharf. Some adult specimens were also 

 captured at the same i)lace and others in a fyke net set by Mr. Ed- 

 wards, the first time they had been so taken. 



The Scup (Stenoiomns chrynops). 



About 300,000 fry were o1)tained from 443,000 eggs of this species at 

 the Woods IIoll station during June, 1800. The eggs are buoyant and 

 hatch in from three to five days. Ninety-five per cent of all the scup 

 taken at this period were milters. After remaining in the traps over 

 twenty-four hours, the females are never found to contain any rii)e 

 spawn. An account of an experiment on the planting- of young scup 

 iu Eel Pond during the summer of 1800 is given in connection with the 

 sea bass. 



The Squeteague {('ynoadon rcyah;.) 



The artificial propagation of this species was first attempted at Woods 

 Holl by Mr. Edwards in June, 1800, when 237,000 eggs were hatched 

 in 3 to 4 days with a loss of only about 10,000. The eggs are buoyant. 

 Nineteen out of twenty of all the squeteague taken were milters, and 

 ripe males occurred as late as June 30, but nearly all the females had 

 spawned before that time. 



The Tautog (Tdnloi/n onilis). 



From sos.OOO eggs of the tautog, secured by Mr. Edwards at Woods 

 Holl during June, 1800, 732,000 embryos were obtained. The eggs are 

 buoyant and hatched in from 3 to 5 days. On June 29, 1890, about 

 ."*0,000 fiy were planted in Eel Pond, where young fish were abundant 

 in the lollowing Novend)er. They did not attempt to escape from the 

 ptmd, but stowed tliemst^lves away in the eelgrass. This species is said 

 to ])(' growing less al)undant every year on the southern coast of New 

 England, 



The Gunner (Clrnolalnun ttdHprrHUH). 



The eggs of the cunner are buoyant and very transparent; about 26 

 are contained in a linear inch. About 50,000 eggs of this species ob- 

 tained I\Iay 22, ISOO, were hatched at Woods Holl on the 5th day, with 

 a loss of only 5,000. The tidal cod Jar was used, the temperature of 

 the water being 50'^ F.
