“…The ndings obtained indicate that milk sh farming is a source of income to the farmers. Indeed, milk sh farming has been reported to contribute signi cantly in terms of nancial security for small-scale sh farmers (Shadrack et al 2021), similar to other sh farming activities in Tanzania (Mulokozi et al 2020). The milk sh farmers in the study area are more likely to obtain higher gross income in the future if they increase production.…”

“…Equally, milk sh farming has been reported to contribute meaningfully to food, nutritional status, income and employment in Kenya (Mirera 2019), Sri Lanka (Dissanayake 2019), and as a food security for small-scale sh farmers in Australia (Shadrack et al 2021). Moreover, milk sh farming has been reported to generate direct employment in Indonesia (Sugama 2007) and Philippines (Salayo et al 2021).…”

The socio-economics and livelihoods of milkfish (Chanos chanos) pond farming to coastal communities is limited in most countries including Tanzania. This study assessed the milkfish (Chanos chanos) pond farming contribution to the socio-economics and livelihoods along the Tanzanian coastline. Sixty three milkfish farmers were interviewed through semi-structured questionnaire. The results indicated that, milkfish pond farming is characterized by low production due to low farmers’ education. The milkfish pond production is postively influenced by farmers’ experience, the number of fingerlings stocked and pond fertilization. However, milkfish pond farming is significantly negatively affected by pond production period and age of the farmers. Interestingly, our results showed that, milkfish pond farming is a source of income to the farmers after selling their fish through retail, wholesale and on-farm sales via mobile phone communications. However, milkfish pond farming in the studied areas is currently not profitable. Interestingly, milkfish pond farming is a source of food, income and employment to the community. Nevertheless, milkfish pond farming is constrained by inadequate feeds, seeds, funds, technical support and existence of theft and predators. Therefore, addressing these challenges is necessary for enhancing milkfish pond farming contribution to the socio-economics well-being and livelihoods support for the coastal communities.

“…The exploitation of fishery resources and aquaculture development, which supplement the production of fish of lower trophic levels and therefore of lower toxic risks, can help meet the fish demands in the growing population of Kendari and the Sulawesi region. The aquaculture of milkfish ( C. chanos ) has been proposed by the FAO as an option to address food security and meet the increasing food protein demand in the Pacific Island countries and territories (PICTs) [ 105 ]. It is one of many species raised to ensure food security and to meet the current demand for dietary protein in the Western Pacific region [ 106 ].…”

This study measured the concentrations of Hg, As, Ni, Cd, and Pb in six fish species commonly consumed in Kendari. Samples were bought within local markets from 2012 to 2017 at the end of the dry season. Results showed that mercury concentrations fluctuated between years and within species, except in the Caranx sexfasciatus, which showed no significant differences (Kruskall–Wallis, p-value > 0.05, df = 5) and an average concentration of 0.371 ± 0.162 µg g−1 DW. Arsenic was found in high concentrations across species and years and varied widely in C. sexfasciatus, the lowest value being 0.32 ± 0.01 µg g−1 DW in 2012 and the highest was 5.63 ± 1.89 µg g−1 DW in 2017. The highest nickel concentrations were found in 2016 across four of the six species. The fish samples displayed very low cadmium and lead concentrations throughout the study. In addition, the potential human health risk due to fish consumption was assessed. This showed that mercury is the only one of the five metals present in concentrations high enough to individually pose a potential hazard, the only metal likely to be accumulated beyond a safe concentration in Kendari. Chanos chanos never posed a toxicological risk based on the results of this research.

“…The inclusion of milkfish ( Chanos chanos ) as an indigenous ‘freshwater’ species warrants explanation: it is a marine fish that supports small‐scale artisanal fisheries, for example in the Solomon Islands and Vanuatu 62,63 but is a marine fish that can be acclimated to freshwater at fingerling stage for aquaculture grow‐out in ponds. Hatchery techniques for milkfish have been established in Southeast Asia for several decades, 64 have been transferred to Kiribati 65 and are currently being established in Fiji.…”

An important driver behind introductions for aquaculture of alien fish species into Pacific Island Countries and Territories (PICTs) is a lack of knowledge about domestication suitability and specific culture requirements of indigenous taxa. Introductions may be appropriate in some circumstances, but in other circumstances, the associated risks may outweigh the benefits, so greater understanding of indigenous species' aquaculture potential is important. This review summarises literature for indigenous freshwater food fish species from Papua New Guinea, Fiji, Vanuatu, the Solomon Islands, Samoa and Tonga, and evaluates their aquaculture potential for food security and/or small-scale livelihoods. A species selection criteria incorporating economic, social, biological and environmental spheres was used to score 62 candidate species. Tilapia (Oreochromis mossambicus and O. niloticus) now established in PICTs were evaluated for comparison. Results show that 13 species belonging to the families Mugilidae (Mullets), Terapontidae (Grunters), Kuhliidae (Flagtails) and Scatophagidae (Scats) have the highest culture potential according to selection criteria. These feed at a relatively low trophic level (are herbivores/detritivores), have comparatively fast growth rates and overall possess characteristics most amenable for small-scale, inland aquaculture.The four top-ranked candidates are all mountain mullets Cestraeus spp., followed by Nile tilapia (Oreochromis niloticus). Lower ranked candidates include three other mullets (Planiliza melinoptera, P. subviridis and Mugil cephalus) and rock flagtail Kuhlia rupestris.Importantly, many species remain data deficient in aspects of their reproductive biology or culture performance. Species profiles and ranked priority species by country are provided with logistical, technological and environmental assessments of country capacities to culture each species.
