APPENDIX C 167 Abundance Indices The 2003 stock assessment for west coast lingcod uses commercial fishery and fishery-independent indices of abundance, such as the following: · NMFS Triennial Shelf Trawl Survey (biomass and associated coefficients of variation) (This survey does not cover rocky habitat, a prime lingcod habitat and therefore has a habitat bias.)

In 2003, there were 1,283 angler trips directed for groundfish on the west coast and, of these, 325 were charter trips, and 958 were private vessel trips. RED SNAPPER Life History Red snapper (Figure C.2)

Although the discarded catch associated with shrimp trawls is not counted toward the [total allowable catch] , it is included in the stock assessment as part of the total fishing mortality.

When available, the MRFSS data from the first two months of the current year replaced the projection for those two months, and this continued as current data became available but was limited to the first six months of the year; the last six months were estimated using previous years' data (Gulf of Mexico Fishery Management Council, 2005a)

The for-hire fishing mode is surveyed using the Vessel Frame Telephone Survey (prior to 2006, this was the Southeast Head Boat Survey) and the Vessel Effort Validation Survey.

In addition, the agents would assign an estimate of the type of gear and fishing area where the landings were caught. The Southeast Fisheries Science Center (SEFSC)

no head boat sampling after 1985 · NMFS's Beaufort Laboratory head boat survey for all states after 1985 · TPWD's coastal sport fishing survey Data on recreational discards were collected by the MRFSS but were not available for Texas landings or for landings from head boats. Red snapper catches from Texas only account for about 2 percent of the annual recreational landings gulfwide.

determined that, in 2002, the stock was not overfished and that overfishing did not occur. However, the Atlantic Striped Bass Technical Committee reported difficulty in determining if overfishing was occurring in 2003 because of divergent patterns in fishing mortality estimates from VPA and analysis of tagging data.

From page 179... ...
Striped Bass Management Board and Striped Bass Plan Review Team are responsible for monitoring the implementation of the fishery management plan. States are granted flexibility to deviate from the standards in the fishery management plan by submitting proposals for review by the ASMFC Striped Bass Technical Committee and Advisory Panel with approval from the ASMFC Management Board.

The shore and private and rental boat fishing modes are surveyed using the MRFSS coastal household telephone survey and the MRFSS intercept survey. The for-hire sector is surveyed using the Vessel Frame Telephone Survey, the Vessel Effort Validation Survey, and the MRFSS accesspoint intercept survey.

From page 181... ...
The 2004 Striped Bass Stock Assessment Technical Committee expressed concern that there was considerable error in the catch produced by the MRFSS in 2003. The MRFSS estimated increases in some of the waves even though fishing effort was reported to have decreased due to hurricanes.
|
From page 182... ...
The MRFSS estimates of catch rate are not used in the striped bass assessment, although the time series of these catch rates have been compared with trends from VPA by the technical committee and found to be similar in recent years.

, as well as complementary information on recreational fisheries. Social sciences information is typically broader sources of information specific to commercial and recreational fishermen, their families, and the fishing community in general.
