  Isostichopus badionotus and you may Isostichopus sp. are a couple of holothuroids rooked in the Caribbean area for Colombia. Until recently, they were believed an individual varieties. Throughout the 12 months, 222 folks of Isostichopus sp. and you will 114 off We. badionotus was accumulated in 2 bays of your Santa Marta part to review their reproductive biology and you may assemble details about their dimensions, weight and you will environment. One another sea cucumber morphotypes shown an annual reproductive course, with a great reproductive seasons out-of September to November, directly linked to the rise within the water temperature and you will water. In sea cucumbers the people build displayed a great unimodal shipping composed of adult individuals and you may a gender proportion of 1:step 1. Isostichopus sp. got the common proportions and you can pounds (193 ± 52 mm and you may 178 ± 69 grams) and you can dimensions and you may lbs at first maturity (175 mm and 155 grams) which had been reduced than We. badionotus (correspondingly, 324 ± 70 mm and you can 628 ± 179 grams; 220 mm and 348 g). When you are 98% regarding Isostichopus sp. everyone was amassed regarding upper 2.5 yards, to your rugged bottoms anywhere between breaks, 73% out-of I. badionotus people were found anywhere between step three and you can 7.8 meters depth, started to the exotic soles. These types of differences imply that administration methods (age.grams. minimum catch size) really should not be a comparable for both ocean cucumbers morphotypes.

  1. Introduction

  Even though ocean cucumber angling is not a traditional activity when you look at the Colombia, for nearly two decades it’s become an extra source of earnings getting local groups and you will anglers on the Colombian Caribbean coast, exactly who extract this funding that have about zero controls [1–4]. Fishing knowledge of nearby countries, such as for instance Panama, Mexico and you may Ecuador show the fresh susceptability out of sea cucumbers to over-exploitation due to reasonable recruitment cost, later maturity and you will thickness-dependent breeding [5–7]. But not, when you look at the Colombia so it interest has been achieved illegally towards various other kinds and you may can be primarily unregulated and unquantified , advised by increasing consult off Asian segments, where ocean cucumber represents good gastronomic happiness regarding higher financial worthy of [8–10].

  Established facts about fishery as well as confiscations created by Colombian environment bodies mean that among the many variety most often stuck as well as most useful matter because of its safety and you will conservation is actually Isostichopus badionotus [1, step three, 11], because it’s perhaps one of the most valuable throughout the Caribbean getting together with cost when you look at the Far-eastern segments ranging from 132 and you will 358 USD Kg -1 . Unfortuitously, fishermen who sell sea cucumbers so you’re able to intermediaries discover an average of only step 3 USD Kilogram -1 [step one, 3].
