The info were presented as the dining tables and you can rates, and therefore the studies was assessed descriptively through assessment that have relevant records, ideas, and you may profession observations.

Length-weight dating

The field observation of your connect constitution showed that Liza macrolepis and you Sober dating website can Moolgarda engeli have been predominant. A total of 242 L. macrolepis and 109 M. engeli was tested and mentioned from the research. The length of men L. macrolepis ranged out of 141.cuatro – 202.step one mm (164.8 ± mm), and you will ranged out of 129.2–185.4 mm (159.1 ± mm) for females. The human body pounds regarding male L. macrolepis ranged off 34.eight grams in order to 89.6 g (54.step 1 ± thirteen.3 grams when you look at the average), and you can twenty eight.8 grams to g (47.9 ± nine.52 grams when you look at the mediocre) in females. The size of the male Meters. engeli ranged regarding 109.9–188.5 mm (161.9± mm) and 116.5–182.step three mm (154.step one ± mm) for females. The body weight of one's boys try 13.six – 108.5 gram (47.6±19.step three gram), and that of your ladies try 14.2–75.step 1 gram (41.cuatro ± gram). Raw data arrive due to the fact underlying data 37 .

The outcomes of one's LWRs analysis on the L. macrolepis showed that the male fish got a b value of dos.49 that have a relationship coefficient off 0.93, together with female seafood got a-b value of 1.81 and a relationship coefficient from 0.82 (Shape 2a and you can 2b). Hence, the male and girls L. macrolepis showed negative increases models, and you can a method relationship anywhere between weight and you will complete amount of the new seafood. The results from LWRs analysis away from male Meters. engeli indicated that an average b value try 3.twenty-two having a good coefficient correlation out of 0.89. The female Yards. engeli got the common b worth of 3.41 which have a great coefficient relationship from 0.93 (Contour 3a and you may 3b). These types of investigation imply that the male and people Yards. engeli keeps an optimistic allometric gains pattern, and you may a robust correlation anywhere between fat and full size.

R2 - determination coefficient, r - correlation coefficient, N - number of fish tested.

R2 - devotion coefficient, r - relationship coefficient, Letter - level of fish sampled.

Predicated on testing season, the common b worth of L. macrolepis (male and female) is 2.78 inside the deceased seasons and 2.twenty-eight when you look at the wet-season (Figure 4a). The brand new b property value M. engeli is actually step three.42 for the inactive year and you may 2.forty-eight during the wet season (Figure 4b). These types of investigation indicate that the fresh new b well worth is lower when you look at the wet season for both variety. New spread plots out of predict practical weight to own respective seen size, because determined throughout the ingredient out of length–weight regression, is shown from inside the Shape 2c and 2d and Shape 3c and you may d. The brand new regression designs let you know a distinction amongst the observed and you may predicted progress models in types.

Position products. The outcome revealed that a man L. macrolepis got a great Fulton's standing (K) foundation of just one.19, and cousin pounds status factor (Wr) out of ; once the women got a good Fulton's position factor of just one.19, and you will relative lbs standing factor of . Likewise, men Yards. engeli got a good Fulton's reputation grounds of 1.05, and you can relative lbs standing foundation out of ; while the fresh people possess Fulton's updates grounds of 1.06, and relative lbs standing factor of (Table step one). Considering testing year, the fresh Fulton's condition of L. macrolepis in the dry season is step one.twenty two and also for the relative weight; when you look at the wet season they certainly were step one.19 and , correspondingly. On the other hand, the newest K and you may Wr values away from Yards. engeli from inside the dead year had been step 1.03 and you may , respectively; in wet-season these people were 1.09 and you will , correspondingly (Desk 2). The knowledge of your temperatures have been seen aesthetically. The occasions are mostly wet through the testing throughout the wet season, so the turbidity are large in this year.
