  Conceptual

  Isostichopus badionotus and you may Isostichopus sp. are two holothuroids rooked on the Caribbean area for Colombia. Up until now, these were experienced one kinds. Throughout the one year, 222 individuals of Isostichopus sp. and you can 114 out-of We. badionotus was indeed amassed in two bays of your own Santa Marta area to study its reproductive biology and collect information regarding the proportions, pounds and you can habitat. One another water cucumber morphotypes exhibited a yearly reproductive duration, that have an excellent reproductive 12 months from September in order to November, directly related to the rise in water heat and you will rain. In both sea cucumbers the populace framework displayed a good unimodal distribution consisting of adult somebody and a sex proportion of just one:step 1. Isostichopus sp. got an average size and you will pounds (193 ± 52 mm and you may 178 ± 69 grams) and you may size and you will weight at first maturity (175 mm and you can 155 g) which was far lower than We. badionotus (respectively, 324 ± 70 mm and 628 ± 179 grams; 220 mm and 348 grams). While you are 98% away from Isostichopus sp. people were accumulated in the top 2.5 m, into rugged bottoms ranging from breaks, 73% of I. badionotus individuals were receive ranging from step 3 and you can eight.8 yards breadth, opened with the sandy soles. These types of differences indicate that management methods (age.grams. lowest connect size) shouldn’t be the same both for ocean cucumbers morphotypes.

  step one. Inclusion

  No matter if ocean cucumber angling is not a classic pastime in Colombia, for nearly twenty years it’s become an additional source of earnings to have indigenous teams and you will fishermen on the Colombian Caribbean coast, just who extract that it funding with very nearly zero controls [1–4]. Angling experience with surrounding countries, particularly Panama, Mexico and you can Ecuador demonstrate new susceptability out of ocean cucumbers in order to over-exploitation due to low recruitment costs, late maturity and density-created reproduction [5–7]. not, inside Colombia it activity remains accomplished illegally into other varieties and you may are generally unregulated and you can unquantified , encouraged because of the growing demand off Far eastern areas, where ocean cucumber is regarded as an effective gastronomic pleasure off highest monetary really worth [8–10].

  Established info on this subject fishery plus confiscations produced by Colombian environment authorities mean that one of several species oftentimes trapped as well as most useful matter because of its shelter and you can conservation was Isostichopus badionotus [step one, step three, 11], since it is perhaps one of the most rewarding regarding Caribbean interacting with rates in Asian places anywhere between 132 and 358 USD Kilogram -step one . Regrettably, fishermen whom promote ocean cucumbers so you can intermediaries receive on average merely step three USD Kilogram -step one [step one, 3].
