“…While the total number of publications was comparatively small in contrast with other taxa, five reports focused on long-term datasets of several decades of sirenian stranding, rehabilitation, and post-release monitoring [59,60]. Several reports also discussed details of the rehabilitation process, such as hand-rearing and milk replacement formulas [61,62].…”

Rehabilitation of marine mammals is performed throughout the world, yet the impact of rehabilitation on individuals and populations is questionable given the lack of robust information on the rehabilitation process and post-release monitoring in most cases. The goals of this study were to perform a systematic review of existing literature on marine mammal rehabilitation between 2000–2023 to determine the current state of rehabilitation and to evaluate the rehabilitation and conservation factors that could be used to build a framework to assess the health of rehabilitation programs worldwide. A total of 418 publications encompassing 52 species of marine mammal were included in the systematic review. Rehabilitation efforts focused mostly on pinnipeds, and North America was the most represented region. Data are scarce for both short- and long-term post-release survival across species. Reports about species threatened with extinction were significantly more likely to include information about conservation parameters than those species of least concern. A meta-analysis demonstrated a fairly strong fit of the dimensions of the proposed framework for a rehabilitation health index. Further refinement would strengthen the utility of this tool for both rehabilitation and conservation programs.

“…Partnerships of government authorities with state and private zoos play an important role by providing the necessary veterinary care, husbandry and research opportunities. Such partnerships have been established successfully in the USA (including Puerto Rico), Brazil and Venezuela, where manatees have been held in captivity (Adimey et al, 2012; Normande et al, 2015; Boede & Mujica-Jorquera, 2016). Manatees are difficult to study in the wild and therefore the knowledge and expertise gained through management of captive individuals is of great value.…”

The Endangered Antillean manatee Trichechus manatus manatus is one of the most threatened aquatic mammal species in Mexico and the wider Caribbean region. The decline of this subspecies is mainly a result of historical exploitation and the impact of current coastal development. The conservation strategies adopted for the Antillean manatee include habitat protection, reduction of the most severe threats, and the rescue of stranded, orphaned or injured individuals and their management in captivity. This latter strategy has produced positive outcomes in some countries but has been the subject of controversy in others, including Mexico. We analyse the benefits and challenges associated with the management of captive manatees in Mexico, and the consequences of a lack of government policy and strategy for the post-rehabilitation release of individuals. We describe the evolution of this controversy from 1997–2017 in Mexico, analyse the consequences and implications for the conservation of the species, and propose an integrated management strategy that could address the issues raised. Although this strategy has been developed in the context of Mexico, it is applicable to management of this species across the Caribbean region.

“…In Venezuela, manatees are protected by the Law for the Protection of Wild Fauna, and since 1978 several legal actions have been taken to reduce manatee hunting (Rodríguez and Rojas-Suárez, 1995). By 1996, an indefinite prohibition of poaching was set up and nowadays the species is enlisted as Endangered in this country (Boede and Mujica-Jorquera, 2016). Antillean manatees have been reported in the Venezuelan states of Zulia, Apure, Sucre, and Anzoátegui (O'Shea et al, 1988Correa-Viana et al, 1990; including the Orinoco River basin (Castelblanco-Martínez, 2004, Rivas-Rodríguez et al, 2012, and coastal areas of the Caribbean sea (Debrot et al, 2020).…”

In Venezuela, Antillean manatees (Trichechus manatus manatus) have declined mainly due to habitat loss and degradation, but other threats to the species persist. The objective of this work was to investigate the manatee distribution and conservation issues in Maracaibo Lake, Venezuela. Aiming to collect evidence on manatee presence, we conducted 404.14 hours of boat-based surveys and observations from the shore during 2003, 2004, 2009, and 2010. Environmental parameters were collected in areas where manatees were observed including pH, temperature, dissolved oxygen, salinity, transparency, and depth. Also, we recorded plants or algae that could serve as potential food for manatees. We developed 96 informal and opportunistic talks with local fishermen, to gather information about manatee occurrence, boat traffic, and people’s perception of the species. Finally, we reviewed published and unpublished documents containing information on manatees in Maracaibo Lake. The resulting database contains information on 39 sightings and 13 reports of dead manatees. The known causes of death were poaching, vandalism, boat collision, and entanglement in fishing nets. The Maracaibo Lake offers many suitable habitats for manatees, but also faces a wide array of conservation problems that represent critical threats to this endangered subspecies. Long-term monitoring of this population and potential sources of mortality is highly needed.
