a) Isostichopus sp.
The average TL try 193 ± 52 mm (± SD), restrict 380 mm and you will minimal 75 mm. These types of values ranged based on sex (+ = 195 ± forty five mm, > = 202 ± 52 mm and you will instead of gonad 179 ± 61 mm). People rather than an effective gonad had been significantly smaller than the fresh new males (n = 221; K = 6.513; p = 0.039).
Length-volume delivery is actually unimodal that have an optimum regarding the variety of 180 to 215 mm (Fig 2A). The brand new L50 are based from the 175 mm (95% rely on period: 174–176 mm) (Fig 2C). The littlest private having gonads was a male (110 mm).
An excellent and you may B shipment regularity off duration and you will lbs Isostichopus sp.; Elizabeth and F distribution volume regarding duration and you can weight Isostichopus badionotus; C and you can D length and you will weight in the beginning readiness Isostichopus sp.; Grams and H size and you can weight initially maturity Isostichopus badionotus.
The typical BW (± SD) is 179 ± 69 grams, restrict 558 grams and you can lowest 18 g (+ = 187 ± 58 grams, > = 190 ± 71 grams and you may in place of gonad 154 ± 77 grams). The people instead gonads was basically reduced big than lady and guys (letter = 221; K = ; p = 0.003).
Regularity distribution of BW are unimodal having an optimum into the all of the 153 to 198 grams (Fig 2B). The latest W50 is mainly based within 155 g (95% trust period: 154–156 g) (Fig 2D). The tiniest individual compiled having gonads are 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 distance-frequency shipments are unimodal, having a highest throughout the directory of 355 to 390 mm (Fig 2E). The new L50 was established at the 220 mm (95% confidence period: 217–221 mm) (Fig 2G). The littlest personal amassed that have gonads was a male (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; F2,111 = ; p = 0.001).
Frequency delivery from BW is actually unimodal which have a peak about directory of 607 in order to 642 grams (Fig 2F). The new W50 is actually depending at 348 grams (95% rely on interval: 344–350 g) (Fig 2H). The smallest individual obtained which have gonads is actually a woman (363 g).
Both in sea cucumbers new gonad are consisting of several tufts regarding tubules having a racemose appearance found at the fresh new anterior prevent of your own coelom, and this involved reside every perivisceral cavity at stage away from maturity (III). Along with of your own gonad regarding one another ocean cucumbers ranged regarding beige–whitish so you’re able to ocher, in the place of an apparent dating ranging from colour and gender. Only one case of hermaphroditism try found in Isostichopus sp., in which step 3% of your gonad contained sperm and you may 97% oocytes.
Histology showed 4 of your 5 stages regarding gonadal development advised by the Ramofafia mais aussi al. . In this study the new indeterminate sexfinder login phase (I), where in actuality the gametes don’t but really possess discussed mobile structures that ensure it is its distinction, was not noticed. An explanation of your own histological characteristics out-of gonad development was revealed about S1 Appendix.
cuatro.5 Gonad List (GI)
In morphotypes the lowest GI values have been submitted on earliest 1 / 2 of the year, towards the low opinions set for Isostichopus sp. (0.4 ± 0.2%) and We. badionotus (0.8 ± 0.6%). Away from Could possibly get onwards, a steady improve is actually seen, reaching their maximum really worth in August with cuatro.eight ± 0.9% and you can 7.six ± 0.9%, respectively (Fig 3A and you can 3B), coinciding to your escalation in drinking water temperature together with onset of the latest wet year (Fig 3C and you will three dimensional). Ranging from Sep and December the latest GI diminished quickly, indicating substantial spawning, tape in the a GI of 1.5 ± 0.5% to own Isostichopus sp. and you can 1.step 3 ± 0.4% having I. badionotus.
