Money on the Table - The Profit Potential in Effective Fishery Management
My Topics Simplified Fishery Management Lobster Management Programs in Other Places The Rhode Island Experience My Take on the California Lobster Fishery The Future of Fishery Management and How to Profit from Sustainability
The 3 Basic Fishery Controls 1.Recruitment –requires adequate spawning stock, –then determined primarily by nature. 2.The minimum legal size –Creates a floor, doesnt help the stock above MLS –Contributes to yield per recruit 3.The fishing mortality rate –fraction of the fishable stock taken each year, –determined by fishing effort, –Determines average size of animals. Less fishing means higher catches!
Fishing Mortality Controls – Leaving Lobsters in the Water Direct - Annual Total Allowable Catch Indirect – Fishing Effort Control Even less direct – –Closed season –Prohibition on egg-bearing lobsters –Closed areas (effect depends on migration)
Traditional U.S. Atlantic Approach No TAC No effort control Counter excess catch with discard requirements –Minimum size –Egg-bearing females –V-notched females –Maximum legal size –Throw back 86 of every 100 lobsters caught
Current U.S. Atlantic Approach No TAC, but tightening Reference Points 6 of 7 Lobster Management Areas have Individual Trap Allocations, meant to be transferable. A trap is not a unit of fishing effort. More regulations sure to follow as each allocated trap turns into more fishing effort.
Canadian Atlantic Inshore Approach No TAC Limit licenses, uniform trap limit (300) Short legal season Still overfishing Chronic controversy (Unimaginable trap limits by New England standards)
New Zealand, most of Australia –Individual transferable quotas Australian states had transferable traps
South Australia provides good lesson Southern Zone prospered after switch from Transferable Traps to ITQs Northern Zone kept ITTs and collapsed

RI Lobster Fishery Experience Fished down in late 1800s Constant scientific warnings –Reliance on newly recruiting lobsters Steadily increasing traps (300-1600 from 1970-1997) Increasingly variable catches –Heavy fishing pressure increases variability –No standing stock of adult lobsters to take up the slack when environmental conditions produce poor year class –Phenomenal fishing in late 1990s, then collapse Regulatory response increases discard rate to 86% High costs – low revenue
RI Lobster Fishery Experience 1,000+ commercial lobster licenses issued each year 1990-2003 – meaningless 2003 – 278 reported more than 1 pound 2007 – Approx 200 recd Individual trap allocation Based on average number of traps used to catch an individuals annual landings
Southern New England Trap Allocation Formula Predicted Traps Calculator Pounds landed =1500 Predicted traps =228 Allocation was lower of predicted or reported.
California Lobster Fishery 200 Miles of coast, out to 3 miles = 600 sq miles 200 licenses 300 traps per license average? 60,000 traps 100 traps per sq mile
California Lobster Fishery 200 licenses – 151 transferable 300 traps per license average? 750-1,000 traps max Will each license go to the max as transfers take place? Will big operators try to stay ahead of the pack?
California Lobster Resource Most legal lobsters caught in first year? With no limit on traps, will more traps take more lobsters in first year? Take 20% of legal animals each year? More and larger lobsters in standing stock.

Marine Stewardship Council Requirements The dependence of productivity on abundance has been estimated and used to estimate potential Target Reference Points and associated uncertainties. A Limit Reference Point (LRP) has been established and its level is computed at appropriate time intervals to determine whether the stock is depleted. The management system incorporates and applies an adaptive and precautionary exploited stock strategy The management system applies information through implementation of measures and strategies (by rule or by voluntary action of fishery) that demonstrably control the degree of exploitation of the resource in the light of the natural variation in ecosystems. There is a process in place for rapid development of a recovery plan for target populations should significant depletion occur. Significant depletion can be defined as dropping below the LRP.
Investing in Conservation Reduce fishing effort – save costs Leave legal animals to grow and reproduce – larger biomass Harvest greater yield at lower cost – fishermen make money on high CPUE Reduce variability Profit from sustainability
Get a Piece of the Stock Competition for a natural resource is a zero-sum game – produces the same or less fish at higher cost. Allocation allows least cost harvest. Creates an incentive to build wealth in fish stock, rather than maximize cash flow. Individual trap allocations are better than nothing, but far from ideal.
Can a Lobster Fishery Achieve Its Profit Potential without Quota Shares or an Effective Trap Limit?
