Meet the dolphins along Louisiana's coast

In a fishing conversation, “dolphin” can also mean dolphinfish, another name for mahi-mahi. Mahi-mahi are fish; the bottlenose dolphins on this page are mammals.

The bottlenose-dolphin profile from the National Oceanic and Atmospheric Administration (NOAA) describes bays, estuaries and open coastal water as well as offshore habitat. An estuary is a coastal area where fresh water and seawater mix.

Dolphins eat fish and other marine prey. A group moving or feeding near a boat can be fascinating to watch, but it isn't a signal to throw bait or assume fishing will be good at that spot. Describe the movement you actually see before assigning a purpose such as feeding, playing or approaching people.

Choose a permitted shore position or the operator's agreed boat position, with room to stop without blocking others. Keep watching the water after the first animal disappears rather than move after each glimpse. Notice:

• Which direction it was traveling.
• Whether another dolphin surfaces nearby.
• Whether the group keeps moving or stays in one area.

Record the place, time, visible body or fin, direction and sequence. If several backs appear, keep uncertainty about the number of animals rather than assume each glimpse was a different dolphin. Unseen parts stay unseen; a brief view may not support a complete identification or explanation of the behavior.

For an illustrative note, ‘three surfacing glimpses moving left; number of individual animals uncertain’ describes the view without claiming three dolphins. Keep visible movement separate from a guess that the animals were feeding, following the boat or behaving as they did on a previous visit.

Binoculars or a camera zoom can help from shore or a stable boat position. Keep the walkway or rail clear for other people. If dolphins come toward a vessel, let the operator manage the boat and leave the animals room to pass.

Don't chase, touch, swim after or feed wild dolphins. NOAA's dolphin guidance explains how feeding can encourage animals to approach people and fishing gear.

Fish scraps and unused bait count as food too. Keep them contained rather than turn a sighting into a feeding opportunity. Assign storage and cleanup of bait, scraps and loose line before fishing; guests waiting for a turn have the same responsibility. If dolphins begin interacting with fishing, tell the crew the position and visible interaction and follow its direction for managing the gear. Don't make another bait placement to draw the animal closer.

Use the current marine-life viewing guidance when planning an observation outing. Room to travel and breathe matters more than filling the camera frame.

Before booking, establish whether dolphin observation is the main activity or a possible addition to fishing, and how much of the day is riding, searching and watching. Check the assigned boat's viewing position, seats, breaks, shade, toilet and boarding arrangements for everyone coming. A sighting photograph doesn't establish the activity or a guaranteed encounter. The wildlife-outing guide helps compare the actual options.

Keep the departure or shore entrance, requested arrival, expected return and time for unloading or walking back with that plan. Ask what happens if dolphins aren't seen or the boat, route or hours change. A substitute fishing activity or location needs to fit the group's interests, practical needs and onward travel too.

Bring drinking water, suitable clothing and binoculars or a camera if you already have them. Watching from a clear permitted position doesn't require a specialist camera.

For an animal that appears injured, caught in gear or stranded ashore, use the Louisiana Department of Wildlife and Fisheries' wildlife reporting guidance. Record a usable location, observation time, visible problem and whether it is still there, with the last-seen position, time or direction if it disappears. Mark uncertain details rather than diagnose the injury. Leave hands-on help to the response team and follow its instructions; don't turn reporting into a reason to approach or handle the animal.
