Triggers of fishing gear loss incidents in small-scale fisheries in Peru.

This study sought to identify the causes of gear loss and determine the main fishing grounds where losses occurred. Data were collected between 2003 and 2023 from 17 ports along the Peruvian coast. Of 8742 fishing sets analyzed, bottom longlines reported the most incidents, (n = 456 with 38,130 hooks lost) of gear loss.

At-sea solid waste production by a small-scale fishery in Peru.

Marine litter is a growing environmental problem for which fisheries-sourced waste remains poorly understood. In Peru, there is an ongoing challenge of waste management from the small-scale fisheries fleet given the lack of facilities to receive the variety of debris produced by fishers, which includes hazardous wastes such as batteries. In this study, onboard solid waste production was monitored daily by land-based observers upon landing at the port of Salaverry, Peru, from March to September 2017.

Lessons from 12 years of marine fauna stranding data in the south of Peru.

In Peru, while several mass mortality events have been reported in the last two decades, there has been minimal systematic stranding monitoring. In this study, we report on repeated stranding monitoring that took place between October 2003 and October 2015, at Ite beach, Tacna (17° 54' 47" S 70° 58' 21" W). The objectives of the study were to assess the proportion of strandings by taxon and whether there were seasonal effects on abundance of stranded marine fauna.

Patterns of spatial and temporal distribution of humpback whales at the southern limit of the Southeast Pacific breeding area.

Understanding the patterns of spatial and temporal distribution in threshold habitats of highly migratory and endangered species is important for understanding their habitat requirements and recovery trends. Herein, we present new data about the distribution of humpback whales (Megaptera novaeangliae) in neritic waters off the northern coast of Peru: an area that constitutes a transitional path from cold, upwelling waters to warm equatorial waters where the breeding habitat is located. Data was collected during four consecutive austral winter/spring seasons from 2010 to 2013, using whale-watching boats as platforms for research.
