a) Isostichopus sp.
The typical TL try 193 ± 52 mm (± SD), limitation 380 mm and lowest 75 mm. These types of philosophy ranged depending on sex (+ = 195 ± 45 mm, > = 202 ± 52 mm and you will without gonad 179 ± 61 mm). The individuals instead an excellent gonad had been somewhat smaller compared to the latest guys (n = 221; K = six.513; p = 0.039).
Length-regularity shipments are unimodal that have a top on the directory of 180 to 215 mm (Fig 2A). Brand new L50 was created within 175 mm (95% rely on period: 174–176 mm) (Fig 2C). The smallest personal that have gonads is a male (110 mm).
An excellent and you can B shipment frequency off duration and you may lbs Isostichopus sp.; Elizabeth and you may F shipment volume away from size and lbs Isostichopus badionotus; C and you can D length and you will pounds at first readiness Isostichopus sp.; Grams and H duration and lbs to start with readiness Isostichopus badionotus.
An average BW (± SD) is 179 ± 69 grams, restrict 558 grams and minimal 18 grams (+ = 187 ± 58 grams, > = 190 ± 71 g and without gonad 154 ± 77 g). The individuals versus gonads was less hefty than female and men (letter = 221; K = ; p = 0.003).
Volume delivery of the BW are unimodal that have a maximum in the range of 153 to help you 198 grams (Fig 2B). The newest W50 try depending on 155 g (95% rely on interval: 154–156 g) (Fig 2D). The smallest individual collected with gonads is actually a male (39 grams).
b) Isostichopus badionotus.
The average TL was 324 ± 70 mm (± SD), maximum 480 mm and minimum 110 mm (+ = 329 ± 55mm, > = 341 ± 64 mm and without gonad 240 ± 78 mm). The individuals without gonad were significantly smaller (n = 114; Fdos,111 = ; p = 0.001).
The length-regularity shipping is unimodal, having a maximum about listing of 355 so you’re able to 390 mm (Fig 2E). The fresh new L50 is actually founded in the 220 mm (95% trust interval: 217–221 mm) (Fig 2G). The smallest personal built-up that have gonads try a masculine (210 mm).
The average BW was 628 ± 179 g, maximum 999 g and minimum 72 g (+ = 654 ± 152 g, > = 669 ± 145 g and without gonad 383 ± 200 g). The individuals without a gonad were significantly less heavy (n = 114; Fdos,111 = ; p = 0.001).
Volume delivery out-of BW try unimodal with a maximum throughout the a number of 607 in order to 642 g (Fig 2F). The brand new W50 was based in the 348 grams (95% believe period: 344–350 grams) (Fig 2H). The tiniest individual collected having gonads is a lady (363 g).
In both ocean cucumbers the gonad try comprising several tufts out of tubules that 
have an excellent racemose looks located at the brand new anterior prevent of one’s coelom, which involved undertake every perivisceral cavity in the phase regarding readiness (III). Colour of your gonad away from each other water cucumbers ranged out of beige–whitish so you can ocher, in the place of an evident relationships between color and you may gender. Just one matter-of hermaphroditism was noticed in Isostichopus sp., in which step three% of one’s gonad contains jizz and you can 97% oocytes.
Histology displayed cuatro of your 5 degrees out-of gonadal creativity suggested from the Ramofafia et al. . Within research the latest indeterminate phase (I), in which the gametes don’t yet provides outlined mobile formations that enable it to be their differentiation, wasn’t noticed. A reason of one’s histological functions away from gonad advancement was found about S1 Appendix.
4.5 Gonad Index (GI)
In morphotypes a reduced GI beliefs was basically registered about basic 1 / 2 of the year, towards the reasonable opinions set for Isostichopus sp. (0.cuatro ± 0.2%) as well as for We. badionotus (0.8 ± 0.6%). From Will get ahead, a progressive improve was observed, getting together with their restriction value from inside the August having cuatro.eight ± 0.9% and you can 7.six ± 0.9%, correspondingly (Fig 3A and you will 3B), coinciding for the boost in liquids temperature while the onset of brand new rainy year (Fig 3C and you may three-dimensional). Anywhere between September and you may December the latest GI reduced rapidly, proving enormous spawning, tape in the a great GI of 1.5 ± 0.5% having Isostichopus sp. and you may 1.step 3 ± 0.4% to have I. badionotus.
