Patterns in longitudinal distribution of American Eel (Anguilla rostrata) population characteristics in rivers of Puerto Rico

Torres-Molinari, A., Engman, A. C., Pacifici, K., Dolloff, C. A., Myers, B. J. E., & Kwak, T. J. (2023, July 18). FISHERIES MANAGEMENT AND ECOLOGY, Vol. 7.

By: A. Torres-Molinari n, A. Engman*, K. Pacifici n , C. Dolloff *, B. Myers  n & T. Kwak n 

author keywords: Anguilla rostrata; Caribbean; dams; population characteristics; rivers; sex determination
TL;DR: This first island-wide study to evaluate the distribution of density, length, and sex in relation to distance from the mouth of 23 stream reaches in five rivers in Puerto Rico indicates that Puerto Rico could significantly contribute to the spawning population and strengthen knowledge of American Eel in the Caribbean.

Big runs of little fish: first estimates of run size and exploitation in an amphidromous postlarvae fishery

CANADIAN JOURNAL OF FISHERIES AND AQUATIC SCIENCES, 78(7), 905–912.

By: A. Engman n, T. Kwak n  & J. Fischer n

TL;DR: The first simultaneous estimates of an APF run size and harvest are presented, revealing the first empirical evidence that amphidromous migrations are large-magnitude material subsidies of lotic ecosystems. (via Semantic Scholar)

Fish Assemblages and Fisheries Resources in Puerto Rico's Riverine Estuaries

MARINE AND COASTAL FISHERIES, 11(2), 189–201.

By: A. Engman n, T. Kwak n , J. Fischer n & C. Lilyestrom*

TL;DR: The results provide the best available information about the spatial variability of assemblages and fisheries resources, which will benefit future conservation and fisheries management efforts, which are needed due to increasing anthropogenic impacts, such as illegal harvest, invasive species, and water diversions.

Puerto Rico Sicydium goby diversity: species-specific insights on population structures and distributions

NEOTROPICAL BIODIVERSITY, 5(1), 22–29.

By: A. Engman n, G. Hogue *, W. Starnes*, M. Raley & T. Kwak n 

author keywords: Gobiidae; amphidromous; Sicydiinae; biodiversity; conservation
TL;DR: Information is revealed on the spatial patterns of distribution, relative abundance, population structure, and observed molecular diversity among Sicydium taxa in Puerto Rico’s river systems that is essential to advance ecological and evolutionary knowledge of Caribbean fish assemblages, guide stream fish conservation, and to effectively manage fisheries.

Drought Facilitates Species Invasions in an Urban Stream: Results From a Long-Term Study of Tropical Island Fish Assemblage Structure

Frontiers in Ecology and Evolution, 6(AUG).

By: A. Ramírez* , P. Gutiérrez-Fonseca *, S. Kelly *, A. Engman n, K. Wagner*, K. Rosas*, N. Rodríguez *

Contributors: A. Ramírez* , P. Gutiérrez-Fonseca *, S. Kelly *, A. Engman n, K. Wagner*, K. Rosas*, N. Rodríguez *

TL;DR: This study documents drought-facilitated invasions by several aggressive and highly ecologically competitive species, highlights the importance of the natural flow regime as a source of environmental resilience to invasions in tropical island streams, and provides an example of how climate change has and will likely continue to alter Caribbean stream fish assemblages.

Ecology and conservation of the American eel in the Caribbean region

FISHERIES MANAGEMENT AND ECOLOGY, 26(1), 42–52.

By: T. Kwak n , A. Engman n & C. Lilyestrom*

author keywords: Anguilla rostrata; Anguillicoloides crassus; dams; fish distribution; Puerto Rico; river
TL;DR: Realised threats include dams and other migratory barriers, habitat loss and alteration and pollution; exotic species and commercial fishing are impending threats; and the least understood is climate change. (via Semantic Scholar)

Recruitment phenology and pelagic larval duration in Caribbean amphidromous fishes

FRESHWATER SCIENCE, 36(4), 851–865.

By: A. Engman n, T. Kwak n  & J. Fischer n

author keywords: fish recruitment; amphidromous; tropical island; pelagic larval duration; stream fish; phenology; flow regime
TL;DR: Recruit abundance, recruitment phenology, and pelagic larval duration of several Caribbean amphidromous fish species in multiple rivers in Puerto Rico are quantified and the last-quarter moon phase during the months of June through January are identified as periods of maximum amphidromeous fish recruitment to freshwater streams.
