“…A similar recent resurgence of seaweed farming has been reported as a direct outcome of the collapse of tourism in Bali resulting from the COVID-19 pandemic [20]. In South Sulawesi, seaweed production has increased markedly since mid-2020, despite lower farm-gate prices, apparently due to the reduced employment opportunities associated with COVID-19 impacts on the economy and employment opportunities [13].…”

“…Over the past two decades production increased annually before peaking in 2014, after which production began to decline slightly (Figure 1). However, a recent survey of seaweed production in South Sulawesi, conducted using remote sensing, concluded that official production statistics are gross over-estimates of actual production [13], and this has also been expressed anecdotally to the authors by Indonesian seaweed processors. Note that some of the discrepancies in reported production can be attributed to differences in the reporting metric (wet or dry weight), which should be clarified to avoid confusion.…”

“…Seaweed propagules (small clumps of seaweed from the previous harvest) are tied to the main lines The second key feature of seaweed production in Indonesia is the involvement of large numbers of smallholder farmers. An estimated 267,000 households benefit from seaweed farming in Indonesia [13], with the average mariculture farm size varying from about 0.1 ha in Bali to 1.0 ha in South Sulawesi [11]. Most (78%) brackishwater pond farms surveyed in Takalar Regency, South Sulawesi, had less than 1 ha of pond area each [37].…”

“…In 2009, the farm-gate price then dropped to USD 1208 per tonne dry weight [12]. More recently the farm-gate prices in Indonesia appear to have stabilised at between USD 550 and 750 per tonne dry weight (http://www.jasuda.net/, accessed 4 September 2020), before declining again due to COVID-19 impacts on trade [13]. The price paid for seaweed in Indonesia appears to be in line with the seaweed prices typically paid by China [12], and lower than average world prices.…”

Seaweed farming in Indonesia is carried out throughout much of the archipelago and is mainly undertaken by smallholder farmers. Indonesia is the largest global producer of the red seaweeds Kappaphycus and Eucheuma, which are used to produce carrageenan, and is a major producer of Gracilaria, which is used to produce agar. Seaweed farming is attractive to farmers in rural coastal communities because capital and operating costs are low, farming techniques are not technically demanding, labour requirements are relatively low (allowing farmers to engage in other livelihoods), and production cycles are short (30–45 days), providing regular income. Using reported values for seaweed-farming income, we conclude that seaweed farming can, but does not always, lift rural households above the Indonesian poverty line. In addition to direct financial benefits, seaweed farming also contributes to human and social capital within seaweed farming households and communities. Achieving continued economic and social benefits from seaweed farming will require additional policy development, as well as research and development to support improved and more consistent seaweed productivity and improved product quality at the farm level, provision of effective extension and technical support services, and diversification of the existing value chains in order to reduce the impacts of price fluctuations that are associated with limited global commodity chains.

Price and revenue projections under alternative policy shocks due to the coronavirus: Canadian lobster and snow crab

The coronavirus will have serious consequences for the fishing industry. The purpose here is to simulate price and revenue outcomes for Canadian lobster and snow crab markets under alternative policy shocks due to the coronavirus. Predictions are based on three policy scenarios representing upper and lower bounds on the range of possible landings and economic outcomes for the period 2019–2021. Based on past research, demand equations for both the lobster and snow crab markets are used to empirically simulate price projections. The results for snow crab are startling with predicted serious declines in price and generated revenue, particularly for Québec and Newfoundland and Labrador (NL). Compared to 2018, projections suggest a decline in average revenue for 2021 of − 18% Gulf, − 32% Maritimes, − 53% Québec, and − 57% NL. The outcome for lobster is not as bleak, projections showing a 21% decline in revenue for 2020 but with recovery in 2021.
