In this work, we proceeded to estimate the shrimp export demand in Ecuador for the year 2019. The shrimp sector is one of the most dynamic within the country's economy, in recent years it has increased its contribution to the Gross Domestic Product (GDP). The objective of this work is to determine exports of Ecuadorian shrimp taking into account the preponderant factors that have caused this sector to be affected both positively and negatively. It was carried out through a non-experimental, descriptive design, where statistical information from the shrimp sector was collected. The Media Difference Method was used. The result obtained indicates that by 2024 there will be a demand of around 1,925 million pounds of white shrimp, in addition to exports, the country will have income by 2024 of about 4,572 million US dollars. This will correspond to the increase in the market and therefore the consequent demand for the product for human consumption in order to meet the needs and better guarantee food security, this forecast will determine the growth of shrimp farms and the potential demand of the marketing destinations.

“…Although water quality could explain this trend, ontogenetic migration patterns could also be at play. The wet season could coincide with the reproductive season of the titi ( X. riveti ) and tiger ( R. byrdi ) shrimps, which could result in an increase in species richness and biomass in this region (Hernández‐Noguera et al, 2016 ; Mora‐Lara, 1973 ). However, the higher species richness and biomass recorded during the wet season at the outer sites could also be attributed to these sites being farther away from domestic, industrial, and agricultural discharges (Duque et al, 2020 ).…”

“…Macroinvertebrate species were classified as resident or migratory according to the frequency of use of the estuary by each species (Díaz‐Ochoa & Quiñones, 2008; Gamboa‐García, Duque, & Cogua, 2018; Hendrickx & Sánchez‐Vargas, 2005; Hernández‐Noguera et al, 2016; Mora‐Lara, 1973). The dynamics of the macroinvertebrate community structure were assessed using richness and biomass.…”

The anthropogenic discharges of inorganic nutrients impact water quality, affecting the macroinvertebrate assemblage and food safety. The main objective of this study was to examine the seawater quality and macroinvertebrate dynamics in muddy habitats of Buenaventura Bay, Colombian Pacific. Macroinvertebrates were captured using artisanal trawl nets during different seasons and along four sampling sites. Multivariate analyses (canonical correspondence analysis and generalized additive model) were used to assess the effects of variations in nitrite, nitrates, phosphate concentrations, and physicochemical variables (salinity, pH, dissolved oxygen [DO], temperature, and total dissolved solids [TDS]) of water on the macroinvertebrate assemblage. Richness was the highest at sites with high salinity and temperature and low concentrations of nitrites and TDS. The densities of the commercial shrimp species Xiphopenaeus riveti and Rimapenaeus byrdi were the highest at sites with higher DO and alkalinity, and lower nitrate concentrations. The swimming crab Callinectes arcuatus was dominant at sites with low water quality. In summary, in the transitional season and at the inner sites of Buenaventura Bay, it was observed the lowest water quality due to high nitrate concentration. High nitrate concentration was highlighted as the main anthropogenic factor that could decrease the capture of target macroinvertebrate species for food and livelihoods of artisanal fishermen and their families. Thus, macroinvertebrate communities may be vulnerable to increased inorganic nutrient inputs, which could affect estuarine water quality and ecosystems services.
