Fishing

• Food for human consumption

– Globally, fish is ~20% of animal protein

consumed

• Animal feed (both aquaculture & livestock)

• Natural products

– Inverts, fish & kelp

• Cultural identification

• Direct employment for 200 M people globally

What Landings Mean

• Landings are the required reporting of

amounts of harvested fish

• Landings are a function of …

stock size, type of fishery, effort, technology,

harvest policy, market & reporting honesty

• Care must be taken in assessing time

histories of landings

What is Catch??

• Catch = (Catchability) (Effort) (Biomass)

Catchability is f(skill, technology,…)

Effort is hours, # trawls, … = f(profit, …)

Biomass is the stock abundance

• Profit to fishery = (price) (Catch) – (Costs)

Profit drives effort…

Price = f(market, …)

Costs = f(fuel, distance to port, biomass, …)
