“…The impact of the destruction of the mangrove ecosystem will be very large, both from an ecological and economic perspective (Su et al 2021). The marine food chain will be destroyed, leading to a decline in the fisheries sector (Macusi et al 2021). The coastal community's protection from sea-level rise, storm surges, and tsunamis will be affected (Marois et al 2015).…”

“…At the tree stage, the highest was again A. marina with a value of 0.37 while the lowest was A. alba with 0.22. Low diversity implies that the ecosystem is under pressure (Singh 2020) and in declining conditions (Macusi et al 2021). As the mangroves live in environments with high salinity and muddy substrates, survival only occurs for those species with high adaptation abilities after a strict selection (Noor et al 2006).…”

Hasibuan IM, Amelia R, Bimantara Y, Susetya IE, Susilowati A, Basyuni M. 2021. Vegetation and macrozoobenthos diversity in the Percut Sei Tuan mangrove forest, North Sumatra, Indonesia. Biodiversitas 22: 5600-5608. The mangrove forest offers a habitat for a variety of marine species, including macrozoobenthos. Macrozoobenthos live at the bottom of the waters on hard to muddy substrates, where they break down mangrove debris, ensuring microorganisms' ease in decomposing organic matter into inorganic materials that provide nutrients to producers in the water. The study aimed to determine the vegetation and macrozoobenthos diversity in the Percut Sei Tuan mangrove forest, North Sumatra, Indonesia. This research was executed with vegetation analysis, employing a sampling method in the form of plots, as many as three transects and 66 plots. The sampling of macrozoobenthos was conducted on the substrate surface, roots, and mangrove trunk for three stations and nine plots with a size of 1 m x 1 m. We found 10 true mangrove species where Avicennia marina was the most abundant, found at each seedling, sapling, and tree-stage with an important value index (IVI) of 64.62%, 75.73%, and 92.12%, respectively. Overall, the number of individuals in the species found was 1666.67/Ha at the seedling stage, 1090.91/Ha at the sapling stage, and 842.42/Ha at the tree stage. Seven macrozoobenthos species were found and classified into four classes of Gastropoda, Polychaeta, Mollusca, and Arthropoda, with population abundance values being 9.33 ind/m2 at a station I, 7.44 ind/m2 at station II, and 8.78 ind/m2 at station III. The diversity index (H') of the observed location was determined to be 1.63-2.06, which was classified into the medium category, while H' macrozoobenthos ranging from 1.54-1.81 were classified into the low to moderate category. The observed parameters' physical and chemical factors presented that the condition of the waters in the research area is still considered suitable for supporting macrozoobenthos life, with dissolved oxygen being strongly correlated to macrozoobenthos diversity.

“…The Philippines ranks second in terms of global climate risk due to its vulnerability to climate change impacts [66,67], where it is projected to be a key reason for decline of the fisheries with huge economic costs [37]. Climate change affects the targeted population range and productivity, habitats, and fishery and aquaculture cost [63,68]. Changes in climatic variables facilitate the increased frequency of typhoons, and disease spread, causing physical damage to the farm's pond structure, deterioration of water quality and spread of disease and infection in shrimp ponds [69].…”

“…The Philippines is projected to decrease by 9% its fisheries GDP with the climate change mitigation scenario and a decrease of 18% with the extreme scenario without mitigation [37]. The government should adopt further adaptation measures to prevent the catastrophic impacts of climate change and variabilities with the aquaculture sector [68].…”

“…Moreover, there is a need for increased government investments for developing hatcheries, laboratories, and training technicians adept in good aquaculture practices and able to recognize the early stages of diseases to prevent outbreaks [68]. The government may include crucial investments in smart and artificial intelligence in the aquaculture sector to recognize indicators of diseases even before an outbreak can occur.…”

Aquaculture production is under pressure to increase its production to meet the growing demand for food from a growing population. In the Philippines, aquaculture has experienced the shift from milkfish to prawn with its attractive marketable price. Its intensification has led to negative and positive impacts making its collapse inevitable in the mid-1990s and raised a range of environmental and socioeconomic problems. This paper reviewed the environmental impacts, challenges, and disease outbreaks that overtook the industry using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. We examined gaps and changes required to revitalize the industry to properly take-off. It considers and gives details on the impacts of shrimp culture on the environment e.g. shrimp farm management, marine pollution, disease outbreaks, climate change impacts, and socioeconomic impacts. Moreover, the presence of viral diseases such as White Spot Syndrome Virus (WSSV), Monodon Baculovirus (MBV), Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV), Hepatopancreatic Parvovirus (HPV), and Yellow Head Virus (YHV), have caused socioeconomic impacts with approximate losses of 40,080 mt in 1997 to 51,000 mt in 2014 in the shrimp industry. Recommended strategies were considered to improve the environmental management of shrimp aquaculture, including disease management, and priorities that were highlighted for future research. This management relates to adopting good aquaculture practices on shrimp culture, proper environmental monitoring and sustainable practices at the farm level.
