    Isostichopus badionotus and Isostichopus sp. are a couple of holothuroids exploited throughout the Caribbean area for Colombia. Up until now, they were considered just one species. During one year, 222 individuals of Isostichopus sp. and you may 114 of We. badionotus had been accumulated in two bays of the Santa Marta area to study their reproductive biology and you will collect details about its size, pounds and you may habitat. One another ocean cucumber morphotypes exhibited a yearly reproductive years, with a good reproductive season away from September so you’re able to November, closely associated with the increase within the water temperatures and you will rainfall. In water cucumbers the population design showed an effective unimodal shipments comprising adult someone and you will an intercourse proportion of just one:step 1. Isostichopus sp. got the average proportions and you can pounds (193 ± 52 mm and 178 ± 69 grams) and you can dimensions and you may weight to start with readiness (175 mm and you will 155 grams) that was much lower than We. badionotus (respectively, 324 ± 70 mm and 628 ± 179 g; 220 mm and you can 348 g). When you find yourself 98% regarding Isostichopus sp. everyone was built-up about upper dos.5 meters, for the rocky bottoms anywhere between splits, 73% out of I. badionotus individuals were located ranging from 3 and 7.8 yards breadth, opened into exotic soles. Such differences signify administration procedures meet sudanese women (e.grams. minimal hook dimensions) should not be a similar for both ocean cucumbers morphotypes.

    step 1. Introduction

    Although ocean cucumber fishing isn’t a vintage activity from inside the Colombia, for almost two decades it’s become a supplementary supply of earnings having local communities and you will anglers toward Colombian Caribbean coast, exactly who extract that it capital that have about zero control [1–4]. Fishing experience with surrounding regions, instance Panama, Mexico and you will Ecuador have indicated new susceptability regarding sea cucumbers so you can over-exploitation on account of reduced employment cost, late readiness and you may density-created breeding [5–7]. However, from inside the Colombia which hobby has been achieved dishonestly toward additional species and are mainly unregulated and you will unquantified , encouraged of the broadening request out-of Western avenues, in which water cucumber is an effective gastronomic joy out-of large economic value [8–10].

    Current facts on this fishery also confiscations created by Colombian ecological authorities signify one of many varieties most frequently stuck as well as finest question because of its defense and you may conservation is Isostichopus badionotus [1, step three, 11], because it is one of the most worthwhile on the Caribbean getting together with pricing inside Western segments anywhere between 132 and you can 358 USD Kg -step one . Regrettably, anglers whom offer water cucumbers in order to intermediaries discover typically simply 3 USD Kg -step 1 [step one, 3].
