Fishery observers collect catch data from U.S. commercial fishing and processing vessels. Nationwide, nearly 20 different fisheries are monitored by observer programs. NMFS has been using observers to collect fisheries data from 1972 to the present. Observers have monitored fishing activities on all U.S. coasts, collecting data for a range of conservation and management issues.

The SEFSC manages the Pelagic Observer Program (POP). The POP is based out of the SEFSC in Miami, Florida and began in May 1992.

How many pelagic observers are there?

The POP has a corps of 10-12 observers. They observe about 500 longline sets.

Where do the observers work?

POP observers monitor a mobile U.S. pelagic longline fleet ranging from the Grand Banks to Brazil to the Gulf of Mexico while onboard fishing vessels. Vessels range in size from 35-90 feet.

How long do observers stay onboard vessels?

Trips can last from 2 to 45 days. During an average year, the combined observer corps will spend over 900 days total at sea, based on 70-75 vessel trips.

The distance of a longline set can range from 10 to 40 miles fishing from 200 to 1000 baited hooks about 100 yards apart.

Are there observers on every pelagic fishing vessel?

The POP targets an 8% coverage of the vessels based on the fishing effort of the fleet. Observer personnel must be able to endure adverse environmental conditions while at sea. They are trained in sea survival, medical first aid, fish identification, and the collection of biological and statistical data.

What data do pelagic observers records?

POP observers record:

  • fish species
  • length
  • weight
  • sex
  • location
  • environmental information

How is the information used?

The information collected is used to evaluate the:

  • harvest of pelagic fish stocks
  • status of pelagic fish stocks
  • effectiveness of management measures to control harvest levels

It's an issue with most freshwater fish if you

Ocean fish...even predatory FW fish eat other stuff that bottom feeds and they pick up that flavor, while pelagic predatory fish like tuna eat other smaller fish and crustaceans that feed on krill and plankton.
Part of the issue with tilapia is that unlike other fish they tolerate extreme conditions of poor water quality...they are so tough they can live in fresh OR saltwater and anything in between...so it's easier for people who don't care about water quality to actually get them to market, where other fish would just die from neglect....but when raised properly they are pretty mild and aren't any muddier tasting than other FW fish that live in still waters.
