“…The initial wet weights of 0 dph A. fangsiao juveniles from the current study are similar to previously measured weights of 0.09 ± 0.02 g at 1 dph (Tziouveli & Yokoyama, 2017). In contrast, growth of juvenile A. fangsiao in the current study was two to four times higher compared to previously reported SGRs for both newly hatched and further developed juveniles (Hu et al, 2024; Tziouveli & Yokoyama, 2017; Zheng et al, 2023). These differences in growth performance could be because of differences in used prey and feeding frequency.…”

“…In contrast, juvenile A. fangsiao aged 1 dph that were fed with two to three small shrimp, Neomysis awatschensis , once per day had a mean SGR of 5.0 ± 1.0% day −1 (Tziouveli & Yokoyama, 2017). Likewise, slightly older A. fangsiao juveniles with a mean initial weight of 3.72 ± 0.56 g had a mean SGR of 2.03 ± 0.19% day −1 when fed with live clams, Potamocorbula laevis , once per day (Hu et al, 2024). The influence of different diets on growth has been observed for O. vulgaris sub‐adults (Cerezo Valverde et al, 2013; Estefanell et al, 2011; Morillo‐Velarde et al, 2015).…”

“…Octopus sinensis is a mediumsized merobenthic octopus that can reach over 3000 g and produces large egg clutches of up to 500,000 embryos, which have an indirect development from paralarvae through a settlement stage before they become fully benthic juveniles (Jereb et al, 2014;Joll, 1976;Mangold, 1983;Suzumura et al, 2022). Recent decline in annual catches for both species because of overfished wild stocks has stimulated research on various aspects of their biology, habitat requirements, reproduction, and commercial culture (Cai et al, 2007;Dan et al, 2019;Hamasaki et al, 1991;Hamasaki & Takeuchi, 2001;Jiang et al, 2020aJiang et al, , 2020bPang et al, 2020;Tziouveli & Yokoyama, 2017;Zheng et al, 2023).…”

Replicating maternal care and incubating octopus embryos artificially is advantageous to improve access to embryonic stages, split and share broods, and reduce the required space to culture large quantities of embryos. However, without female care and adequate rearing systems, the risk of bacterial and fungal infections can be high. This study evaluated the potential effects of low‐concentration sodium hypochlorite (NaOCl) as a disinfectant on embryonic survival, hatchling survival, and growth. Embryos of a holobenthic octopus, Amphioctopus fangsiao, and of a merobenthic octopus, Octopus sinensis, were disinfected with 0.004% NaOCl for 3 min either once at the start (IB), at the start and halfway point (RB), and without disinfection (control). Survival of A. fangsiao embryos differed among treatments initially, but the final number of hatchings did not differ among treatments. No differences in the final survival for O. sinensis embryos were observed among the three treatments. Wet weight and growth for A. fangsiao juveniles did not differ among treatments at any point. In contrast, initial and final dry weight for O. sinensis paralarvae from the control treatment were heavier compared to the IB and RB treatments. These results suggest that NaOCl used as disinfectant has a species‐specific effect on early hatchlings depending on the octopus life history.

Farming non-typical sentient species: ethical framework requires passing a high bar

More widespread farming of species not typically used as livestock may be part of a sustainable approach for promoting human health and economic prosperity in a world with an increasing population; a current example is peccary farming in the Neotropics. Others have argued that species that are local to a region and which are usually not farmed should be considered for use as livestock. They may have a more desirable nutrient profile than species that are presently used as livestock. It may also reduce the pressure from hunting on other wild species, and cause less environmental damage than exotic species. We propose a sentiocentric utilitarian framework that could be used to decide whether species that are local, but generally not used as livestock, should be farmed. To illustrate the use of our decision-making framework, we employ two contrasting neotropical case studies: the Spotted Paca (Cuniculus paca) and the Capybara (Hydrochoerus hydrochaeris). We argue that it may be acceptable to use non-sentient species that are typically not farmed as livestock. However, research should determine whether farming them offers human, environmental or sustainability benefits. In addition, we recommend that if invertebrate species are considered for farming, research should be conducted to determine the likelihood that they are sentient. Finally, given the ethical failings of current livestock farming practices, we argue that a high bar must be met if ‘new’ species that are sentient are to be farmed.
