“…Bicol region is endowed with rich fishery resources however are deteriorating and/or in critical condition (Mendoza et al, 2021a(Mendoza et al, , 2021bSoliman, 1994). The declining fishery resources can be attributed to many interlocking human induced factors basically as a result of population growth (Bush & Hirsch, 2005;Mendoza et al, 2021aMendoza et al, , 2021bZhao et al, 2016). In most cases, level of awareness or knowledge about the resource is an important factor for the conservation and management of the resources (Lemke et al, 2010;Nura & Endris 2020;Wilkinson et al, 2006).…”

Knowledge and awareness on the fishery resources of elementary and high school students

Knowledge and awareness on the natural resources among elementary and high school students are important attributes for future resource conservation and management. However, the enslaving features of gadgets and technologies has shifted the focus of the students away from nature-based knowledge and has motivated the government to integrate environmental education (EE) to the basic education programs. However, its implementation has not been successful due to lack of teaching materials and limits on teachers’ capabilities. As such, it was found out that knowledge of elementary, junior high school (JHS) and senior high school (SHS) students on the native and unique natural resources of Bicol Region are almost the same, with an average score of 40%. But intervention through the use of EE teaching materials developed from the research publications and reports of Bicol University Tabaco Campus faculty-researchers showed that an increase of 31%, 21%, and 28% have been observed for elementary, JHS, and SHS students, respectively. However, a significant difference (p<0.05) was observed between high schoolers from urban setting as compared to the upland and island students with regards to the prior knowledge on natural resources, on the other hand, significant change was also observed in the increase of knowledge in upland (30% increase for JHS, and 42% for SHS) and island students (22% and 27% for JHS and SHS, respectively) as compared to the urban students (12% and 17% for JHS and SHS, respectively). No differences were observed for the elementary students across sites. Several factors were identified to influence knowledge and awareness of students such as, access to internet and mass media, exposure to local situations and prior knowledge, and influence of family and community.<br /> Overall, knowledge and awareness of elementary and high school students on the local natural resources are relatively low but existence of local and relevant EE learning materials can help increase them. It is therefore, recommended that EE through the KADUNUNG program should be institutionalized to improve knowledge and awareness of students in Tabaco City.

“…However, volatility in the global market for fish meals has harmed long-term revenue and security in the aquaculture sector [ 3 , 5 ]. In recent years, the gradual exhaustion of marine fisheries resources has posed a serious problem for fish meal production [ 6 ]. In China, for example, marine capture increased more than 20-fold from 0.6 million tons in 1950 to 13.6 million tons in 2011.…”

An overview of microalgae biomass as a sustainable aquaculture feed ingredient: food security and circular economy

2022

Sustainable management of natural resources is critical to food security. The shrimp feed and fishery sector is expanding rapidly, necessitating the development of alternative sustainable components. Several factors necessitate the exploration of a new source of environmentally friendly and nutrient-rich fish feed ingredients. Microalgal biomass has the potential to support the growth of fish and shrimp aquaculture for global food security in the bio-economy. Algal biorefineries must valorize the whole crop to develop a viable microalgae-based economy. Microalgae have the potential to replace fish meal and fish oil in aquaculture and ensure sustainability standards. Microalgae biomasses provide essential amino acids, valuable triglycerides such as lipids, vitamins, and pigments, making them suitable as nutritional supplements in livestock feed formulations. Fish and microalgae have similar nutritional profiles, and digestibility is a critical aspect of the aquafeed formulation. A highly digestible feed reduces production costs, feed waste, and the risk of eutrophication. Due to low input costs, low carbon footprint, wastewater treatment benefits, and carbon credits from industrial CO 2 conversion, microalgae-based fish and shrimp feeds have the potential to provide significant economic benefits. However, several challenges must be addressed before microalgal biomass and bioproducts may be used as fish feeds, including heavy metal bioaccumulation, poor algal biomass digestion, and antinutrient effects. Knowledge of biochemical composition is limited and diverse, and information on nutritional value is scattered or contradictory. This review article presents alternative approaches that could be used in aquaculture to make microalgal biomass a viable alternative to fish meal.
