Assignment task: In response to two of your peers provide additional feedback about how that technology or advancement could be applied to another species of crustacean. For example, many of the advancements have centered around shrimp farming, but could be broadly applied to other species of crustaceans including ornamental species that are in the aquarium trade. For example, one of the advancements in shrimp farming is pathogen free broodstock. Would this apply to other decapod crustaceans? Why or why not? What other issues might that species be facing for advancement in their culture system? Need Assignment Help?

The increasing demand for ingredients in aquaculture feeds, especially for shrimp farming, is raising serious sustainability concerns (Jory, 2018). Shrimp farming relies heavily on high-protein feeds that are traditionally made with fishmeal sourced from wild-caught fish (Burri et al., 2022). This dependence contributes to overfishing and disrupts marine ecosystems, putting additional strain on already vulnerable fish populations (Eggink et al., 2024). As global demand for farmed shrimp grows, finding alternative protein sources has become essential to reduce pressure on marine resources. To address this, researchers are exploring sustainable alternatives such as plant-based proteins, insect meal, and microbial or algal-based proteins (Bordiga et al., 2022; Davis et al., 2019). However, these alternatives present challenges, including limited amino acid profiles in some plant-based proteins and the high cost and scalability issues associated with insect and microbial sources (Bordiga et al., 2022; Guerden et al., 2011). Additionally, the environmental impact of large-scale production of these alternatives, such as land use and carbon emissions, must be carefully managed (Jory, 2018). Developing cost-effective and nutrient-rich feed solutions must be a priority to ensure the sustainability of shrimp farming.
The journal article by Brindhahevi et al. (2024) conducts a life cycle assessment to evaluate the environmental impacts of shrimp feed production in Tamil Nadu, India. It focuses on human health, ecosystem quality, climate change, and resource use. The study identifies significant contributors, such as cast iron used in machinery and electricity consumption, which accounted for notable greenhouse gas emissions. Shrimp feed production contributes 0.2% of global CO2 emissions, highlighting the need for improved sustainability practices. The findings emphasize the importance of developing environmentally responsible strategies to mitigate these impacts as shrimp farming expands globally.
