“…De acuerdo con la metodología de Ortega-Toro et al (2014), las películas previamente acondicionadas a 53% HR y 25°C se secaron durante 24h a 60 °C, y posteriormente, se almacenaron en un desecador de pentóxido de fósforo a 0% HR y 25°C durante dos semanas. El procedimiento se realizó por triplicado para cada formulación.…”

El objetivo de este trabajo es obtener y caracterizar colágeno de diferentes partes residuales del pez de agua dulce Prochilodus magdalenae (Pm) para explorar su aplicación en películas biodegradables. Se utiliza piel, escamas, aletas y cabezas de Pm para extraer colágeno y elaborar películas usando hidroxipropil metilcelulosa (HPMC). Los resultados muestran que la extracción de colágeno con mayor rendimiento se obtiene de la piel. Las mejores propiedades térmicas se observan en la piel y las escamas. Las películas biodegradables se hacen más fuertes, menos rígidas y deformables con la adición de colágeno. Además, se observan dos etapas de degradación térmica típicas del HPMC. Las micrografías revelan que las películas ganan suavidad superficial con la presencia del colágeno, aunque la barrera al vapor de agua se hace ligeramente menor. Se concluye que el uso de colágeno obtenido de residuos de Pm tiene aplicaciones prometedoras para el desarrollo de películas biodegradables.

“…Table 6 shows that the communities' perception of waste management in Ekas Bay has a poor category, with 56.65% of respondents. Lack of attention to waste management will threaten the coastal environment and community health [44]. Government support is needed to overcome the problem of waste on the coast by providing waste management services, personnel, facilities, infrastructure and information about the waste management system [45].…”

The Covid-19 pandemic has generally impacted coastal activities, including mariculture development. A decrease or increase in aquaculture production will influence the aquatic environment and socio-economic of coastal communities. The aims of this study were (1) to analyze mariculture production in Ekas Bay during the Covid-19 pandemic and (2) to evaluate the coastal management based on the coastal community perspective. The study analysis uses both of analysis of comparative and analysis of descriptive. The results showed that the number of floating marine cages and fishery production had increased by more than 500% during the pandemic compared to before the pandemic. From the results of the dept-interview with coastal communities and fisheries extension officers, one of the drivers for increasing the amount of marine production, especially lobster commodity, is the implementation of government policies related to lobster management. Coastal management implementation has a good category with 65,03% of response assessment. The study also evaluated household waste management, resulting in a poor category with 56.65% of respondents’ assessment. Household waste needs managed properly to minimize the risk of environmental degradation and decrease marine resources in Ekas Bay.

“…The large number of vessels, the informality of the sector and the area where this activity occurs (pelagic and oceanic waters), increase the difficulties in quantifying and monitoring waste production by government institutions. Efforts to assess waste produced during fishing activities have been made for the port of San Jose, with the authors recommending implementation of a solid waste management strategy for this port (Ortiz-Alvarez et al, 2022). A management plan for solid waste produced during fishing activities has been developed for another locality, Salaverry, which is an important small-scale fishing port home to SSF vessels that use either gillnet or longline fishing gear (Castillo et al, 2018).…”

“…Fisheries waste composition, despite being dominated by plastic items, also includes glass, metal, cloth or Styrofoam items (Niaounakis, 2017; Ramos et al, 2019). There have been attempts in some countries to assess waste production during fishing activities (Purba et al, 2019; Unger and Harrison, 2016) and to promote management of waste produced during fishing activities, including through incentive programmes (Ortiz-Alvarez et al, 2022; Purba et al, 2019; Ramos et al, 2019, Unger and Harrison, 2016).…”

“…In Peru, the generation and management of solid waste is one of the main environmental and health problems faced in both continental and marine environments (Alfaro, 2006; Orihuela, 2018; Ortiz-Alvarez et al, 2022; Solano Sare and Buitrón, 2017). Advances have been made through the Solid Waste Management National Plan (Mejía et al, 2020) by providing a framework to articulate efforts among governmental institutions and reinforce initiatives.…”

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. The analysed small-scale gillnet and longline fishing fleets produced annually an estimated 11,260 kg of solid waste. Of particular concern is the production of single use plastics (3427 kg) and batteries (861 kg) due to their potential long-lasting impacts on the environment and challenges related to their proper disposal. A management plan for solid waste has been developed for Salaverry; therefore, a subsequent assessment was conducted in 2021–2022 of the behaviours and perceptions of fishers regarding the implementation of this plan. Most fishers (96%) reported disposing of their waste on land, except organic waste which is disposed of at sea. While fishers in Salaverry have become more conscious of the issues surrounding at-sea waste disposal and have an interest in better segregating and managing their waste, there remains a need for improved waste management and recycling protocols and procedures at the port to make this possible.
