ignored. The Panel members have no way of telling what the consensus
recommendations were because such a consensus was not reached at the meeting,
but rather we were invited to make comments on a draft workshop report
prepared by NMFS. Consequently the following comments are offered.

In Search of Thresholds for Recruitment Overfishing. ICES J. Mar
Sci., 51:191-205.
In this study we consider the problem of estimating, for management
purposes, a minimum biomass reference level at which recruitment to a fish
stock is seriously reduced. We take an empirical, comparative approach to the
problem by examining observations on a wide range of fish stocks. Eight
methods for estimating spawning stock biomass thresholds for recruitment
overfishing are investigated. Their behavior is tested using stock and
recruitment data for 72 finfish populations, each with at least 20 years of
data. We considered three classes of thresholds defined by : (1) the stock
size corresponding to 50% of the maximum predicted average recruitment; (2)
the minimum stock size that would produce a good year class when environmental
conditions are favorable; and (3) the stock size corresponding to 20% of
various estimates of virgin stock size. The estimators of the first type are
generally preferable because they are easily understood, relatively robust if
only data at low stock sizes are available, and almost always result in higher
levels of recruitment above the threshold.

Recreational fishing for snappers and groupers is conducted mainly from
boats: party, charter, and private boats. Available statistics for snappers
and groupers caught in the Gulf of Mexico indicate that catches by
recreational anglers are substantially higher than those by commercial
fishermen. In 1970, the number of recreational anglers fishing in the Gulf of
Mexico for snappers was estimated at 437,000 and for groupers at 301,000. The
average annual expenditure by salt water anglers was estimated at $178. Thus,
the 437,000 anglers spent about $77.8 million and the 301,000 anglers spent
about $53.6 million in pursuit of their avocation. These numbers probably are
not additive, since the grouper anglers also may have fished for snappers. In
1973, the number of private boats fishing in the Gulf of Mexico was estimated
at 348,595; the number of party boats and charter boats was estimated at 437.
The annual gross revenue for these 437 commercial sport boats was estimated at
$26.9 million. Comparable data for the private boats were not available.

The Fishery Management Plan for Coastal Migratory Pelagic Resources of
the Gulf of Mexico and the U.S. south Atlantic as amended on September 22,
1985, requires statistical reporting of fishing activities on coastal pelagic
fishes for the purpose of providing information for management. A survey of
charterboats was conducted in 1986 under this authority by the Southeast
