Isostichopus badionotus and Isostichopus sp. are a couple of holothuroids taken advantage of on the Caribbean region of Colombia. Until recently, these were sensed just one types. During 12 months, 222 people of Isostichopus sp. and you can 114 off I. badionotus were obtained in two bays of your Santa Marta area to examine its reproductive biology and gather details about its dimensions, pounds and you can environment. Each other sea cucumber morphotypes showed a yearly reproductive period, which escort services in Santa Ana have a great reproductive seasons out-of September so you’re able to November, directly pertaining to the rise in water temperature and you can water. Both in ocean cucumbers the population build showed an effective unimodal distribution including mature some body and a gender proportion of 1:1. Isostichopus sp. got the common proportions and you can pounds (193 ± 52 mm and you may 178 ± 69 g) and you can dimensions and you will lbs to start with readiness (175 mm and you will 155 g) which was reduced than just We. badionotus (correspondingly, 324 ± 70 mm and you can 628 ± 179 g; 220 mm and you will 348 grams). When you are 98% of Isostichopus sp. people were built-up in the upper dos.5 m, into rocky bottoms ranging from fractures, 73% out-of We. badionotus everyone was discover anywhere between 3 and you may seven.8 yards depth, exposed on the exotic bottoms. These types of variations signify management tips (e.g. minimum catch dimensions) should not be an equivalent for water cucumbers morphotypes.

step one. Inclusion
In the event sea cucumber fishing isn’t a timeless activity into the Colombia, for pretty much 2 decades it has become an additional source of money getting indigenous groups and you can anglers towards Colombian Caribbean coast, exactly who extract this resource that have virtually no control [1–4]. Fishing knowledge of surrounding regions, instance Panama, Mexico and you can Ecuador have indicated the newest vulnerability from ocean cucumbers to help you over-exploitation because of lowest recruitment prices, later readiness and you will density-founded breeding [5–7]. Yet not, for the Colombia that it pastime is still carried out dishonestly into the some other species and you will is mostly unregulated and unquantified , advised from the increasing consult out of Asian avenues, in which sea cucumber is considered an excellent gastronomic pleasure away from large financial value [8–10].
Existing suggestions on this subject fishery including confiscations produced by Colombian environmental regulators imply that among the many variety oftentimes trapped as well as greatest question for its coverage and you will maintenance is Isostichopus badionotus [step one, step three, 11], because it is one of the most beneficial on Caribbean getting together with prices into the Far-eastern segments ranging from 132 and you will 358 USD Kilogram -1 . Regrettably, anglers exactly who promote ocean cucumbers so you’re able to intermediaries located an average of merely 3 USD Kg -step 1 [step one, 3].
