Funnel Trap for Live-bearing Fishes 

 Obstruction in neck of funnel is a 

 piece of bent wire, and is open on either

place female fish in funnel and 

 cover over with screen, so she can- 

 not leap out. The small wire pre- 

 viously mentioned will prevent 

 the mother fish from becoming 

 jammed in the outlet, but will al- 

 low the young to pass through and 

 collect in the lower portion of jar. 

 Another very simple and ef- 

 fective arrangement is shown in 

 Figure 102 being merely two pieces 

 of glass laid in an aquarium at a 

 sloping angle and set into two 

 blocks so cut as to leave a slight 

 space between the glasses at the 

 bottom of the V. This opening 

 should be just large enough for 

 the young fish to pass through. 

 The plan has the advantage of 

 giving the female plenty of space. 

 In fact several females could be 



kept in such a "maternity ward" at one time. Unless feeding on daphnia, 

 a small butter dish or similar object should be placed across the bottom 

 of glasses to catch the falling food until the fish can eat it. Also a number 

 of snails in the lower part of the aquarium or jar will be needed to consume

the food that falls through the opening. Snails must breathe air, so keep 

 water level a little below top edges of the sloping panes. An important
