    Isostichopus badionotus and you may Isostichopus sp. are two holothuroids cheated from the Caribbean region of Colombia. Up until now, they were considered an individual species. Through the 12 months, 222 individuals of Isostichopus sp. and you will 114 away from I. badionotus was collected in 2 bays of Santa Marta area to examine the reproductive biology and you can assemble information regarding its dimensions, pounds and environment. One another ocean cucumber morphotypes exhibited an annual reproductive stage, which have a reproductive 12 months out-of Sep so you’re able to November, directly related to the rise in water temperature and you will water. Both in sea cucumbers the population build shown an excellent unimodal shipping composed of mature some body and you may a sex proportion of just one:1. Isostichopus sp. got an average size and you will pounds (193 ± 52 mm and you can 178 ± 69 grams) and dimensions and lbs to start with readiness (175 mm and you may 155 g) that was dramatically reduced than We. badionotus (correspondingly, 324 ± 70 mm and you will 628 ± 179 g; 220 mm and you may 348 grams). When you are 98% out of Isostichopus sp. everyone was accumulated regarding higher 2.5 m, to the rugged bottoms ranging from breaks, 73% regarding I. badionotus individuals were discovered between 3 and you can seven.8 m breadth, open on sandy soles. These distinctions mean that management procedures (elizabeth.g. minimum hook dimensions) shouldn’t be an identical both for ocean cucumbers morphotypes.

    step one. Introduction

    Although sea cucumber fishing isn’t a classic activity inside the Colombia, for almost two decades it is an extra source of earnings getting native organizations and fishermen on Colombian Caribbean coastline, who pull this financing with about zero control [1–4]. Fishing experience with neighboring regions, such as Panama, Mexico and you may Ecuador show the brand new susceptability of sea cucumbers so you’re able to over-exploitation on account of low recruitment rates, later readiness and you may occurrence-built reproduction [5–7]. Yet not, within the Colombia it passion remains carried out dishonestly for the some other variety and you may tends to be generally unregulated and you will unquantified hot bogota girl , recommended because of the expanding consult off Far eastern avenues, where water cucumber represents a gastronomic happiness out-of high monetary well worth [8–10].

    Current info about fishery plus confiscations from Colombian ecological regulators imply that among the many varieties frequently caught and of finest concern for its security and you can preservation is Isostichopus badionotus [1, 3, 11], because it is one of the most beneficial in the Caribbean reaching cost inside Western avenues between 132 and you will 358 USD Kg -step one . Regrettably, fishermen whom promote sea cucumbers so you’re able to intermediaries discovered on average merely 3 USD Kilogram -step 1 [step 1, 3].
