Creel clerks conduct surveys of anglers to gather information that helps fisheries biologists. They count the number of anglers and interview them to learn details like catch rates, time spent fishing, and fish harvested. This provides estimates of angling effort and pressure as well as the health and success of fisheries. Anglers are asked to share catch details and lengths which provide data on species harvested and sizes susceptible to harvesting. The surveys also collect anglers' input to help with regulations.

Ideally, the role of data collection is to support the monitoring of stated objectives and support for management processes. States should ensure that timely, complete, and reliable statistics on catch and fishing efforts are collected and maintained in accordance with applicable international standards and practices and in sufficient detail to allow sound statistical analysis. Such data should be updated regularly and verified through an appropriate system.
Fish Stock Assessment in the Philippines. Chapter 1GinaGallano
A stock assessment is the process of collecting, analyzing, and reporting demographic information to determine changes in the abundance of fishery stocks in response to fishing and, to the extent possible, predict future trends of stock abundance.
(E5) Exercise #5: Gone Fishing
Goals
analyze annual fish landing, mortality, and biomass data;
explain what caused the collapse of groundfish populations in New
England;
define the terms overfishing and overfished;
understand how MPAs can be effective management tools for
preventing and reviving overfished populations;
and examine your role as a consumer in aiding the sustainability of fish
in our oceans.
Background
For as long as people have lived near water, people have fished. Sadly,
in many instances, the history of fishing is paralleled by a history of
overfishing. According to the 2006 Report of Status of U.S. Fisheries,
20% of U.S. fish stocks with known overfishing status are subject to
overfishing and 25% of stocks with known overfished status are
considered to be overfished. An additional four stocks currently
classified as not overfished are approaching overfished status.
Contributing factors to the current level of overfishing include:
technological advances that have made large-scale fishing easier;
too many fishing boats on the water;
international partnerships that allow foreign fleets to overfish in the waters of developing countries;
illegal fishing that violates fishing laws or agreements;
large amounts of bycatch of juvenile fish and non-target species; and
the shortcomings of fisheries conservation and management efforts.
The impacts of declining fish catches are being painfully felt by many coastal fishing communities around the globe.
Jobs are lost and food is scarce. Impacts are also felt in the oceans as other marine species are left with fewer fish to
eat. Overfishing affects the entire marine food web. But how do know when overfishing is occurring or when a
stock is overfished? More importantly, can these conditions be reversed?
Part 1: Overfishing in Georges Bank
Georges Bank is an underwater bank situated along the eastern edge of the Gulf of Maine between Cape Cod and
Nova Scotia. This region is one of the most biologically productive marine areas on the eastern seaboard,
historically accounting for a large percentage of New England's commercial fish landings. The Georges Bank fishery
is particularly well-known for its groundfish—species such as cod, haddock, and flounder that feed near the
bottom of the ocean.
Look at the graph on the next page of trends in Georges Bank haddock catch and mortality from 1969 through
2004.
The histogram shows the annual haddock landing—the amount of fish that are caught and kept to sell.
The red line shows the fishing mortality rate, F—the rate at which fish are removed from a population due
to fishing (as opposed to removals due to natural causes such as disease or predation). F can also be
thought of as the percentage of a population that die in one year due to fishing.

This presentation shows what is aquaculture, the different methods of aquaculture, and why aquaculture is important. Aquaculture benefits the oceans, economy, and environment. It maintains the health of our oceans, lessens the severity of overfishing, and reduces the transfer of diseases in sea creatures. It is a form of agriculture for those regions with poor soils and farming lands. In addition, aquaculture improves the health of the people by incorporating seafood into their diet.
The Monterey Bay Aquarium's Seafood Watch Program: Promoting Ethical ConsumptionSustainable Brands
Jim Hekkers of the Monterey Bay Aquarium discusses the Seafood Watch program, an educational initiative to empower consumers and businesses to make sustainable choices for healthy oceans. It started as an exhibit along with food service menu recommendations, husbandry feed changes, and developed into a guide following member requests. Jim explains with graphs and data how dramatically the biomass of table fish has fallen in just 100 years, the percentage of seafood imports in the U.S., how the guide's recommendation categories work, assessment criteria for capture fisheries and aquaculture, the guide's distribution, partners, and corporate relationships with food service companies, retailers, and suppliers.

Your Wild Ohio - Angler
5/13/2015 Division of Wildlife
Odds are, if you've fished in Ohio long enough, you've probably had an encounter with a creel clerk. These
seasonal employees are hired annually by the ODNR Division of Wildlife and sent out into the field during peak
fishing times of the year to interview anglers. Equipped with a survey and a clipboard, creel clerks record anglers’
answers to a series of pre-determined questions relating to their fishing experience and results for the day. While
this may take about five minutes of your time, the information shared plays a vital role in helping biologists
improve fishing.
Creel surveys have been a fisheries management tool for a long time and get their name from the wicker “creel”
baskets that were once commonly used by anglers to store their catch for the day. Even though most anglers
ditched their creel baskets for coolers and live wells years ago, creel surveys have proven over time to be
essential in determining the effects anglers have on fisheries. Recording what species and sizes of fish are
harvested is still one of the most important pieces of information a creel clerk will gather. However, other important
questions, such as how long you’ve been fishing, what you’re targeting, and what you've caught and released
provide further insights into the health and success of a fishery.
In Ohio, creel surveys are performed annually on Lake Erie and inland reservoirs and less often on the Ohio River
and inland streams. No matter where they are stationed, creel clerks are given two primary duties to get the
information biologists desire. Their first task is to count the number of people fishing. It is important for biologists
to have angler count information because, when combined with the average length of a fishing trip (learned during
the interviews), it provides an estimate of total angler effort. Effort is typically recorded as the total number of hours
anglers spend fishing on a body of water, per day, week or year. Effort can also be divided by the acreage of a
reservoir or mileage of a stream to provide an estimate of fishing pressure. For instance, some of our smaller Ohio
reservoirs might not receive the same amount of total angling effort as larger reservoirs, but when examining the
effort per acre it becomes evident that some are actually much more heavily fished. Understanding the amount of
fishing pressure a reservoir or stream receives is important when considering where regulations may be needed,
as well as where they may be most effective.
The creel clerk’s second task is interviewing all of the anglers just counted to learn some of the finer details of a
their fishing trip. If you've never been interviewed by a creel clerk before, the first thing you can expect is a short
introduction followed by an inquiry of when you began fishing and how many people are in your party. These
details help fine tune the angling effort information derived from the counts mentioned earlier. Next, you’ll likely be
asked what you were fishing for on that particular day, followed by if you've caught anything and if it was released
or kept. This information is the real meat of the survey and provides biologists with estimates of angler catch rates
and harvest rates for specific species of fish. The length of time it takes an angler to catch a targeted species of
fish can be a good indicator of the health of that fishery, and whether or not management strategies need to be
altered to try and improve catch rates. Biologists also use this information to rank fisheries and direct the public to

the best fishing spots in their area. If you have harvested fish, the creel clerk will ask you if it’s okay to measure
them. These lengths provide information about which species are being harvested, what sizes are most
susceptible to harvest, and times of the year most harvest takes place.
Lastly, most creel surveys contain several supplemental questions that vary from year to year and are aimed at
collecting anglers’ input on a wide variety of topics. Fisheries managers often use this opportunity to gauge interest
in potential regulations or to rate the satisfaction of established regulations. So the next time you are approached
on the water by a friendly face in a green shirt with a clipboard and measuring board, please take the time to
answer a few questions, share your catch, and provide your honest opinions. Afterwards, you can take pride in
knowing that you've made a small, but invaluable contribution to the sport fish management at your local body of
water.
