The catch landed and effort expended by private-boat

sport fishermen were studied in southern California

between April and June 1981, in order to determine the

impact of one segment of the sport fishery on local marine

resources. Fishermen returning from fishing trips were

interviewed at launch ramps, hoists, and boat-rental

facilities. This report contains quantitative data and

statistical estimates of total effort, total catch, catch

of preferred species, and length frequencies for those

species whose catches are regulated by minimum size limits.

An estimated 310,000 organisms were landed by 106,000

anglers and 4,000 divers (more than twice the catch and

effort estimated for the previous 3-month period). The

major components of the catch were Pacific mackerel, Scomber

japonicus, 63,000 landed; bass, Paralabrax spp., 61,000

landed; white croaker, Genyonemus lineatus, 52,000 landed,

and Pacific bonito, Sarda chiliensis, 35,000 landed. These

species contributed 70% of the total catch.

Anglers' compliance with size limit regulations was variable. Approximately 89% of all measured bass were legal size. The proportion of legal size California halibut, Paralichthys californicus, rose from 60% last quarter to 79% this quarter. However, the percent of legal size California barracuda, Sphyraena argentea, was very low, 58%. Divers' compliance with minimum size limits dropped slightly: abalone, Haliotis spp., averaged 89% legal. (Document has 31 pages

by southern  Ca l i fo rn ia  a n g l e r s ,  and an estimat:ed 13,800 organisms were landed 
by divers, Thirty-four spec ies  of f i s h e s  and inver tebra tes  accounted f o r  95% 
of the combined ang le r /d ive r  catch. The remaining 5% was composed of 54 f i s h  
and i n v e r t e b r a t e  species .  
Nearly three-fourths of the  ang le r  ca tch  was composed of j u s t  s i x  spec ies :  
P a c i f i c  mackerel, Scornber japonicus,  63,000 f i s h  landed; t h e  t h r e e  ParaZabrax

As i n  t h e  previous q u a r t e r  (January-March) , red abalone, HaZiotis

Semicossyphus pulclier (1,500); and red abalone accounted f o r  t h r e e - f i f t h s  of 
t h e  t o t a l  est imated d i v e r  catch.

The ntlmber of  f i s h e s  landed by anglers  i n  Santa Barbara and Ventura Counties 
was an est imated 27,000, nea r ly  h a l f  of which w e r e  rockf ishes ,

ParaZichthys caZ i fodcus  (Table 7). Divers landed l a r g e  q u a n t i t i e s  of red

rock sca l lop .  -The t o t a l  est imated landings f o r  d ive r s  i n  these  two counties 
was 2,600 organisms. 
Los Angeles County's angler  catch of 140,000 f i s h e s  was dominated by 
su r face  and shallow w a t e r  species ,  including white croaker,  P a c i f i c  mackerel, 
P a c i f i c  bon i to ,  kelp b a s s ,  and ba r r ed  sand bass, ParaZabrax nebutifer.

widely known by t h e  angling publ ic .  S l i g h t l y  l e s s  than 70% of t h e  lingcod 
landed w e r e  l e g a l  s i z e .  The percentage of legal -s ize  Ca l i fo rn ia  barracuda var ied  
widely among counties.  I n  Los Angeles and Orange Counties, where the re  was an 
abundance of l ega l - s i ze  f i s h e s ,  nea r ly  80% of the  f i s h  landed were l e g a l .  How- 
ever, Pn t h e  o the r  surveyed count ies ,  where l a r g e  barracuda were not  a s  
abundant, only 40% of t h e  f i s h  landed were l e g a l  s i z e .  Thus t h e  average per- 
centage of l e g a l  barracuda landed i n  southern Ca l i fo rn ia  was 58%.
