“…One of the systems that first develop in O. maya is the nervous system (Caamal-Monsreal et al 2016;Sanchez-García et al 2017), which occurs in organogenesis with the appearance of the eye spot (Farías et al 2009;Olivares et al 2019;Uriarte and Farías 2014). AChE activity was detected at low concentrations at the blastula phase in the present study, the values increased in the controls at organogenesis.…”

No ecotoxicological information exists on phenanthrene (Phe) exposure in cephalopods, animals of commercial and ecological importance. This study investigated the effect of Phe on two B-esterases, Acetylcholinesterase (AChE) and Carboxylesterases (CbE), in Octopus maya embryos. Octopus embryos were exposed to different treatments: control (seawater), solvent control (seawater and DMSO 0.01%), 10 and 100 µg/L of Phe. AChE and CbE activities were measured at different developmental stages (blastula, organogenesis, and growth). B-esterase activities increased in control and solvent control as the embryos developed, showing no statistically significant differences between them. On the other hand, the embryos exposed to Phe had significant differences from controls, and between the high and low concentrations. Our results indicate that B-esterases are sensitive biomarkers of exposure to Phe in O. maya. Still, complementary studies are needed to unravel the toxicodynamics of Phe and the implications of the found inhibitory effect in hatched organisms.

“…(). This stage in R. fontaniana is characterized by high mortality and zero growth because paralarvae are not capable to manipulate the preys and their digestive system is immature, regardless of the diet (Uriarte & Farías ). What is clear so far is that paralarvae have a programmed growth in length that has to be accomplished with or without food ingested, using their own reserves to accomplish the lack of proper food.…”

“…The complete paralarval stage until settlement and development of early juvenile octopuses have been documented only for O. vulgaris , R. fontaniana, Enteroctopus dofleini and E. megalocyathus (Villanueva & Norman ; Uriarte et al . , ; Uriarte & Farías ,b), resulting in a complex controlled culture.…”

The limited success reported in the paralarval culture of merobenthic octopus is mainly attributed to nutritional problems. This study aimed to determine the effect of live diets on the paralarvae performance during the first 30 days after hatching (DAH). The paralarvae were grown under different treatments: starved (STV) as negative control or fed four diets: Artemia sp. enriched with microalgae (ANCH), Artemia enriched with a commercial enrichment (AOG), Artemia enriched with microalga + commercial enrichment (AMIX) and king crab zoea (ZKC). The paralarval growth and survival were affected by the dietary treatment, with significant higher growth in ANCH and AMIX. STV showed 100% mortality at day 27, whereas all diets resulted within a range from 20% to 33% survival. The endogenous protein and lipid reserves were utilized in all treatments. The 22:6n-3/20:5n-3 ratio increased up to 16% during the experimental period. Alkaline protease activity tended to increase in paralarvae fed ANCH, AOG and ZKC over the first 13 DAH; however, this effect was not observed in trypsin nor chymotrypsin activities. The leucine aminopeptidase activity (LAP) was not affected by the dietary treatment, while alkaline phosphatases increased only at 13 DAH in paralarvae fed ANCH. Indicators of the nutritional status of paralarvae are discussed.
