10-50 FATHOLtS : — Eighteen productive tows (tear-ups occurred on 

 two tows) TJBre made in these depth zones vjith the otter trawl 

 previously descrioed. Fish were caught at an estimated average 

 of 87 pounds per haJ-f-ho'or tow. The greatest catch, approximate- 

 ly 720 pounds in one tow. was made in 19 fathoms at latitude 

 33 40' K. and longitude 77°06.5' ¥. (Station 8, Figure 4). Host 

 of the catch of commercial species talcen in this depth zone con- 

 sisted of soup, butterfish, pigfish, tomtate, pinfish, goatfish, 

 and white-bone porgy. These, plus smaller numbers of sea bass, 

 spot, red porgy, and ventiillion snapper, accounted for about 

 one-half of the tTawl catch in this depth zone; the remainder 

 was a mixture of non- commercial species, including filefish, 

 round scad, lizard fish, and snake fish. 



The absence of large quantities of shrimp in the txrawl 

 catches was surprising, since the local fisherman are Icnovm to 

 catch them vri. th small shrimp trawls in less than 20 fathoms* 

 The 1 l/2-inch mesh liner of the trajil net was small enough to 

 retain shrimp^ and at the outset of the survey it was expected 

 that shrimp would be reasonably abundant offshore. Apparently, 

 at this time of year, they are confined to those estuarine in- 

 shore waters fed directly hy the rivers and creeks which drain 

 into the ocean along the coasts of the southern states* Only 

 six coral shrimp, Sicyonia brevirostris (Sticipson) ^/t were taken 

 in this depth zone. 



In regard to the mechanics of operation^ only two tear-ups 

 were encountered in this depth zone* The first '^as attributed 

 to coral, and tlie cause of the second (a minor tear along the 

 foot-rope) is unknown. 



51-100 FATPIOHS ;— Ten tows were made in this relatively 

 narrow depth zone resulting in an estimated average catch of 

 55 pounds of fish per half-hotir tow. More than three-fourths 

 of the trawl catches in this zone were composed of non-commerc-. 

 ial species, including snake-fish, boar-fish, and spotted hake. 

 The small catch of commercial species consisted largely of 

 butterfish, red grouper, and hogfish. 



27 Identifications of the shrmp caught during the North Caro- 

 lina fisherj^ survey were made by Dr, Fenner Chace of the 

 United States National Museum, Washington, D. C.
