Large-scale patterns of encapsulated embryo development and causal factors determining developmental success in the marine environment have been relevant issues research for decades. We studied embryonic intracapsular oxygen availability Trophon geversianus egg capsules from northern Patagonia (Golfo Nuevo, Argentina). The had a mean duration 112 days (at 12–14°C). initial number eggs per capsule was 197 (mean diameter 270 µm), but on average only four embryos reached juvenile stage. Embryos...
The reproductive biology of a population the edible muricid Trophon geversianus inhabiting an intertidal rocky shore in Golfo Nuevo (Chubut, Argentina) was studied regarding seasonality oviposition and induction under laboratory conditions. Sex ratio differed from 1:1 (female biased). mean shell length 22 mm for males 24 females, although females presented significantly larger maximum sizes. No external sexual dimorphism evident, whereas female snails internally by presence albumin capsule...
Edible marine gastropods are consumed in northern Patagonia without regulations or knowledge of nutritional composition and food quality. We determined total lipids (TL), fatty acid (FA), paralytic shellfish poison (PSP) metal contamination six edible gastropods: Buccinanops globulosus, B. cochlidium, Trophon geversianus, Odontocymbiola magellanica, Tegula patagonica Nacella magellanica. TL was lowest the foot (0.29–0.56%) maximum organs (1.43–3.2%), presenting less than other species around...
Abstract Marine gastropods are consumed worldwide due to their nutritional quality, having important economic value in international markets. In the gulfs of Northern Patagonia (Argentina), marine captured as complementary resources during bivalve artisanal fisheries. this study, we determined biochemical composition reproductive cycle four edible abundant along South-western Atlantic coast: Odontocymbiola magellanica , Buccinanops deformis cochlidium and Trophon geversianus . All studied...
Nacella magellanica is an edible limpet that has been consumed since pre-Hispanic times by human populations along the coasts of Patagonia, but studies its nutritional value and reproduction are not yet available. We investigated reproductive cycle seasonal variation in composition (proteins, lipids carbohydrates) whole body this order to analyse some aspects importance as a formal fishery resource. Throughout single year, spawning period extended over all months except June males, while...
In order to establish management measures for a new resource, the size at first maturity should be studied. This measurement is powerful tool in enabling sustainable exploitation of marine benthic resources. Patagonian gastropods are captured as complementary catches during scallop fisheries. Studies related were performed edible northern Patagonia and have been used creation regulation gastropod made by Secretary Fisheries Chubut Province. The minimum capture some species included this was...
Marine gastropods are a popular seafood, abundant along coastal shores and healthy for human consumption. We studied variations in nutritional components during the gonadal cycle of Tegula patagonica, novel gastropod resource protected by recent artisanal fishery regulation. Similar to other marine consumed worldwide, T. patagonica was found have high protein content (mean ± s.d., 28.8 15.4%) low lipid (1.36 0.43%) carbohydrate (1.7 0.8%) content. The spawning peak registered spring summer,...
The edible marine gastropod Trophon geversianus shows a large geographic distribution along the southern tip of South America, inhabiting both rocky intertidal and shallow subtidal zones, with distinct behavioural responses to environmental stressful conditions (desiccation, temperature amplitude high irradiation). Nevertheless, its reproductive biology has been poorly reported date. We studied gametogenic cycle an shore population from northern Patagonia (Argentina), in order investigate...
