Plight of Ocean

• exploited fish population decline in abundances.
• -its follows pattern: individual sizes decline, total catch declines, fishing effort increases (as effort increases, alternative species are sought)
• -sequence: largest to most profittable to smaller less profitable, as each species is depleted.

• British Columbia ling cod.
• 2. Baleen whales off Pacific Ocean. from Blues to Minkes

takes results of many separate studies and pool them to common statistical analysis.

• 1. food web
• 2. foundation species.

• healthy to degraded.
• degraded:
• 1. low fish biomass
• 2.high fleshy algal cover
• 3. low coral cover
• 4.high density of microbes
• 5. low coral survival

losing large fish = uncontrol growth of algae. this excess is not consumed but disintegrates to more particulate organic carbon dissolved organic carbon. <<these are feeding grounds for microbes to form.
