To describe the octopus fishery

Objective

Methodology •  Camuy to Peñuelas •  September 2016-June 2017

Methodology

Fisher Buyer

•  Fish markets •  Boat ramps •  Shore

Business •  Restaurants •  Kiosk

Point of Sales Capture

Fisher Interview •  Questions

– Age – Fishing mode – Duration – Capturing site – Equipment – Frequency – Species identification – Disposition

Point of Sales •  Questions

–  Business type –  Octopus origin

•  % Imported vs Local •  $ Imported vs Local

–  Is there a season? •  Restaurants and kiosk

–  How is it prepared? –  How much is sold per day, per week?

RESULTS

THE FISHER

Results

•  30 fishers – 5 were dedicated octopus fishers

•  Age 40 to 70 yrs. •  Capture gear: Garampín o bichero (hooks) •  Depth: 1-30 feet •  Zone: Rocky shore and Cays.

Results

Results •  30 octopus fishers

5 3 with fishing license and reporting 1 expired license

2 Not licensed

•  Sold directly to business or particular clients; not to fish market.

•  25 fishers- –  Personal consumption. –  To be used as bait.

The octopus species

Octopus vulgaris •  Common octopus •  Maximum length -3 ft. (1.3 m) (Roper

et al 1984) •  Max weight- 22 lbs. (10 kg) Roper et

al. (1984) •  Habitat-rocky zones, reefs and sea

grass beds •  Diurnal habits (Humann, P. &

Deloach, N., 2002) •  Depth- 1-650 ft (0-200m) •  Between 100,000 and 500,000 eggs

(Anderson and Wood, 2012). •  Planktonic larvae (40 days) •  Most abundant species in commercial

fisheries worldwide (Josupeit, H., 2008).

Results •  A total of 120 octopus were measured

–  118 were O. vulgaris

Total length (mm)

Octopus briareus •  Generally known as the “Ethical octopus”

–  It has several common names: pulpo manta, pulpo elástico o gigante y pulpo barraclava.

•  Max. length- 3 ft. (100 cm) Roper et al (1984)

•  Max. weight- 3 lb. (1.5 kg) •  Habitat- mainly reefs, but also in rocky

zones and sea grass beds •  Nocturnal habits- (Humann and Deloach

2002) •  Depth- 1-75 ft. (0-22 m) •  Between 150 y 950 eggs (10-14 mm)

(Anderson and Wood, 2012). •  No planktonic larvae (Mather et al, 2010).

Results

•  Some fishers identify O. vulgaris as the male and O. briareus as the female of the same species.

•  O. briareus has several common names: – South-Ético – Cabo Rojo-Barraclava – North-west-Pulpo gigante o pulpo

elástico.

– Camuy-Pulpo Manta.

Species identification

Coloration

• O. vulgaris-creme or dark brown

• O. briareus- blue

Coloration O. briareus O. vulgaris

Eye coloration: O. briareus O. vulgaris

Is there a season?

•  North coast : –  June-October; peak August –  Weather condition is a critical factor in this area.

•  South coast- –  October-January –  Closer to shallow areas due to a decrease in

temperature and mating.

Point of sales

Fish Markets •  19 fish market visited •  11 or 58% sold octopus •  1 mentioned it also buys imported (Spain) •  Price (retail) $5.00 per pound. •  Average sold 70 lbs. per week. •  Seasonal

Kiosks •  10 kiosks visited •  1 buys directly from fisher •  1 fish market •  Supermarket, importers, big chain commerce. •  Average sold 20 lbs. per week. •  How is it prepared?

–  Boiled for salads –  Mofongo –  Sushi –  Turnovers

Restaurants •  60 restaurants visited •  50 restaurants sold octopus on their menu •  88% buy imported octopus.

•  Spain, Vietnam, Philippines, Mexico •  9% buys local octopus. •  63.3% do not buy local octopus ever. •  Importers, food supply companies, fish markets and local fishermen •  Average sold per week 35 lbs. (maximum 200 lbs). •  How is it prepared?

–  Boiled for salads, sauces –  Mofongo –  Sushi –  Turnovers

Recommendations

•  There is a need for species identification. •  Standarized measuring protocol (Total

length? Mantle? Weight?). •  Size at sexual maturity? •  Protect by seasonal clousures? •  Cover the south east, east and north east

coast of Puerto Rico.
