CRUISE 71-5-6 SPORTFISH INVESTIGATIONS 
Prepared by Parke Young 
Vessel:  N. B. SCOFIELD 
Dates: August 24 - September 6, 1971 
Locality: The nearshore waters of Baja California. 
Purpose: 1. To capture, tag, and release sand bass, P~aZabrax nebuZifep. 
2. To recapture sand bass tagged and released during cruise, 
70-8-6, to determine growth rates of bass at liberty for 
a one-ye~rperiod. 
3. To make incidental collections of fishes and invertebrates. 
Results: 'Tagging - A total of 1176 sand bass was tagged and released 
in Sebastian Vizcaino Bay, 28o~2'N, 114°23'W. 
Recaptures - Only one sand bass was recaptured from the 694 
fish released in Sebastian Vizcaino Bay during 
cruise 70-S-6. At release, this bass was 498 mm 
total length. At recapture, it was 500 mm, a 
growth increment of 2 rom over a 344 day period. 
There was no evidence of a migration. 
General - Because the bass taken for tagging during this 
cruise were from 22 fathoms, each one had to be de-
flated before it could be tagged and released. A 
large hypodermic needle inserted into the air bladder 
at a point above the pectoral fin allowed air to 
escape, which made it possible for a released fish 
to return to the bottom. An estimated 10-15 percent 
of the, total bass taken did not warrant tagging. In-
cidental catches conslsted of Pacific mackerel,·Scombera 
japonicus; giant sea bass, StereoZepis gigas; lizard 
fish, SynodUB Zucioceps; sanddabs, CithaPicthys sp.; 
golden spotted rock bass,ParaZabraax auPoguttatus; , 
kelp bass, ParaZabraa:r; clathratu8; spotted sand bass, 
ParaZabpax maauZatofasciatus; barracuda, sphy~aena 
argenteus; California yellowtail, SepioZa dorsalis; 
and ocean whitefish, CauZoZati~us princeps.
