  Abstract

  Isostichopus badionotus and you will Isostichopus sp. are a couple of holothuroids rooked throughout the Caribbean area for Colombia. Up until now, they certainly were felt just one species. Through the 1 year, 222 people of Isostichopus sp. and 114 regarding We. badionotus was in fact gathered in 2 bays of Santa Marta area to examine their reproductive biology and gather information on its dimensions, pounds and habitat. Each other water cucumber morphotypes exhibited a yearly reproductive stage, that have a reproductive year out-of September to November, closely related to the rise in the water temperature and you can rain. In sea cucumbers the people build showed an excellent unimodal shipments consisting of adult anybody and a gender proportion of just one:step 1. Isostichopus sp. had the average dimensions and you may pounds (193 ± 52 mm and you will 178 ± 69 grams) and you will size and weight in the beginning maturity (175 mm and you may 155 g) which was lower than I. badionotus (respectively, 324 ± 70 mm and you will 628 ± 179 g; 220 mm and you will 348 grams). If you are 98% regarding Isostichopus sp. people were gathered about upper 2.5 yards, towards rugged bottoms between breaks, 73% off We. badionotus individuals were located anywhere between 3 and 7.8 yards breadth, started into the sandy soles. These differences imply that government steps (age.grams. minimal catch size) really should not be an identical for both sea cucumbers morphotypes.

  step 1. Inclusion

  Even in the event water cucumber angling is not a timeless interest inside the Colombia, for almost two decades it has become a supplementary source of money to own local organizations and you can fishermen to your Colombian Caribbean coastline, just who extract that it financing having very nearly no regulation [1–4]. Fishing experience with neighboring places, including Panama, Mexico and you can Ecuador demonstrated new vulnerability from sea cucumbers to help you over-exploitation due to lowest recruitment costs, later readiness and you can occurrence-centered reproduction [5–7]. Yet not, during the Colombia so it passion remains carried out dishonestly toward different kinds and you can are generally unregulated and you will unquantified , encouraged by the growing consult off Western areas, in which sea cucumber is an effective gastronomic glee off large economic value [8–10].

  Current records about this fishery including confiscations from Colombian environment authorities signify one of many varieties most often trapped and of most readily useful concern for the safeguards and conservation try Isostichopus badionotus [1, step 3, 11], because it is perhaps one of the most beneficial on Caribbean interacting with rates when you look at the Western areas ranging from 132 and you can 358 USD Kg -1 . Regrettably, anglers who promote ocean cucumbers so you’re able to intermediaries found normally merely step three USD Kilogram -step 1 [step one, 3].
