Dolphins of Tampa Bay

The dolphins of Tampa Bay are common bottlenose dolphins, and NOAA Fisheries manages them as a separate Tampa Bay stock because it treats the dolphins of each Gulf bay, sound and estuary as a unique stock (NOAA Fisheries stock assessment report).

Many Tampa Bay dolphins stay put. The NOAA report says long-term residency has been reported from Tampa Bay in studies dating from 1986 to 2009, alongside Sarasota Bay, Lemon Bay and Charlotte Harbor to the south (NOAA Fisheries). The same report says geographically and socially distinct subgroupings of dolphins have been identified in Tampa Bay.

For Tampa Bay, Urian and colleagues in 2009 described five discrete communities, counting the adjacent Sarasota Bay community, that differed in their social interactions and ranging patterns (NOAA stock assessment). NOAA notes that the structure exists even though nothing physical, no island chain or narrow channel, divides this large, open embayment.

The bay's edges behave differently from its interior. NOAA describes the mouths of large estuaries as mixing areas and cites a 1986 study that documented dolphins from several different areas at the mouth of Tampa Bay, and it reports fall and winter increases in Tampa Bay dolphin numbers (NOAA Fisheries).

No current count exists: NOAA lists the Tampa Bay stock's abundance as unknown and its Potential Biological Removal as undetermined, while recording a minimum of 3.0 human-caused deaths and serious injuries a year for 2015 to 2019 (NOAA Fisheries, Table 1).

Source: NOAA Fisheries, Northern Gulf of Mexico Bay, Sound, and Estuary Stocks. Table 1 gives no year for a Tampa Bay abundance estimate, and NOAA treats any estimate based on data more than eight years old as unknown or undetermined for management purposes; the report says the current population sizes for all but three of these stocks are considered unknown.

NOAA considers every one of these bay stocks strategic except Sabine Lake, the Mississippi River Delta and Sarasota Bay/Little Sarasota Bay, because most stock sizes are unknown but likely small enough that a few deaths could exceed PBR (NOAA Fisheries). The status of the stocks relative to their optimum sustainable population is unknown, and the species is not listed under the Endangered Species Act.

A point worth knowing before quoting any Tampa Bay dolphin number: the version NOAA posts carries the note that this SAR has not been revised, apart from a technical update that moved Florida Bay into the Gulf table (NOAA Fisheries). The report, dated May 2021, says nine stocks had individual reports completed or drafted and the remaining 23, Tampa Bay among them, are assessed in this collective report, so its mortality figure covers 2015 to 2019.

NOAA Fisheries asks Tampa Bay boaters, kayakers and paddleboarders to stay at least 50 yards, or 150 feet, from wild dolphins and to limit any viewing to 30 minutes (NOAA Fisheries, Guidelines and Distances).

Sources: NOAA Guidelines and Distances and NOAA, Protect Wild Dolphins. NOAA also warns that a lone boat is rarely the only one: prolonged exposure to several vessels raises the chance that marine mammals are disturbed, which applies to every boat that approaches the same Tampa Bay animals in a day.

The 50 yard figure is guidance, while feeding and harassment are illegal: NOAA states that it is illegal to feed or harass wild dolphins and encourages observing them from a distance of at least 50 yards (NOAA Fisheries), a guideline that applies on Tampa Bay as on other U.S. waters.

Under federal rules, feeding a Tampa Bay dolphin means offering, giving or even attempting to give it food or non-food items, and running a boat from which someone feeds dolphins counts too (50 CFR 216.3).

The definition in the Code of Federal Regulations excludes the routine discard of bycatch during fishing operations, and the routine discharge of waste or fish byproducts from fish processing plants or other platforms when it is otherwise legal and incidental, so routine bycatch discards on Tampa Bay are outside the definition while offering or attempting to give food is inside it (eCFR, 50 CFR 216.3). NOAA's Protect Wild Dolphins page states that feeding or attempting to feed wild dolphins is prohibited under the Marine Mammal Protection Act and its regulations (NOAA Fisheries).

Harassment of a Tampa Bay dolphin has two tiers under the MMPA. NOAA explains that Level A harassment is any act of pursuit, torment or annoyance with the potential to injure a marine mammal in the wild, and Level B covers acts with the potential to disturb one by disrupting behavior such as breathing, nursing, feeding or sheltering (NOAA Fisheries, Feeding or Harassing FAQ).

This is not an abstract issue in Tampa Bay. NOAA's stock report records that provisioning, the feeding of wild dolphins, was recorded for four dolphins within the Tampa Bay Stock area in 2019 while they were swimming in a local canal, and it notes that the MMPA defines feeding as a form of take (NOAA stock assessment).

Fishing gear is one of the human causes behind the Tampa Bay stock's recorded deaths and serious injuries, and NOAA describes depredation of recreational fishing gear and associated entanglement and ingestion of gear as increasing through much of Florida (NOAA Fisheries).

NOAA lists Tampa Bay among the bay stocks likely involved in the hook and line gear interactions it reviewed for 2015 to 2019 (NOAA stock assessment). It describes emerging questions about potential links between provisioning, the feeding of wild dolphins, and depredation of recreational fishing gear.

The nearest measured example comes from next door. During 2006, at least 2% of the long-term resident dolphins of Sarasota Bay, the community that adjoins the Tampa Bay communities, died from ingesting recreational fishing gear (NOAA Fisheries).

For Tampa Bay anglers NOAA's guidance is direct: feeding wild dolphins is illegal, viewing should be from at least 50 yards, and dolphins that learn to associate people with food can die after becoming entangled with fishing hooks and lines (NOAA, Protect Wild Dolphins).

A stranded, injured or dead dolphin in Tampa Bay is reported to the NOAA Fisheries Southeast Marine Mammal Stranding Hotline at (877) WHALE-HELP, 877-942-5343, or to the FWC Wildlife Alert Hotline at (888) 404-3922 (NOAA Fisheries, Report a Stranded Animal).

NOAA's Florida stranding list includes the Florida Aquarium in Tampa and Clearwater Marine Aquarium in Clearwater among the organizations in the response network (NOAA Fisheries). NOAA says numerous organizations are trained and ready to respond, and it asks that people and pets be kept back at least 50 yards, or 150 feet, from a stranded marine mammal.

NOAA's Dolphin and Whale 911 app is another way to report a stranded marine mammal in Tampa Bay or elsewhere, and it is available for Apple devices (NOAA Fisheries).
