The information was indeed demonstrated since dining tables and you will figures, and therefore the research was basically examined descriptively as a consequence of testing which have relevant records, theories, and you can field observations.
Length-weight relationships
The field observation of the catch constitution revealed that Liza macrolepis and Moolgarda engeli was basically prevalent. All in all, 242 L. macrolepis and 109 Yards. engeli had been sampled and you may counted in the investigation. The size of men L. macrolepis varied out of 141.4 – 202.step 1 mm (164.8 ± mm), and you can varied out-of 129.2–185.cuatro mm (159.step 1 ± mm) for females. One’s body weight off male L. macrolepis ranged of 34.seven g so you’re able to 89.6 g (54.step one ± thirteen.step three g from inside the mediocre), and twenty-eight.8 grams so you’re able to grams (47.nine ± nine.52 g inside mediocre) in women. Along a man Yards. engeli varied away from 109.9–188.5 mm (161.9± mm) and you can 116.5–182.step three mm (154.step one ± mm) for women. The human body weight of your boys was 13.6 – 108.5 gram (47.6±19.step three gram), and that of the females are 14.2–75.1 gram (41.4 ± gram). Intense investigation are available once the hidden studies 37 .
The results of your LWRs investigation on L. macrolepis revealed that the male fish got a b worth of dos.forty-two having a relationship coefficient of 0.93, therefore the people fish had a b worth of 1.81 and a relationship coefficient of 0.82 (Shape 2a and 2b). For this reason, a man and you can females L. macrolepis exhibited negative development models, and you will a media correlation anywhere between weight and full duration of brand new fish. The outcome away from LWRs investigation of male Meters. engeli revealed that an average b really worth is actually step 3.twenty two with an excellent coefficient relationship of 0.89. The feminine Yards. engeli had the average b worth of step 3.41 with a beneficial coefficient correlation regarding 0.93 (Contour 3a and 3b). Such study mean that the male and girls Yards. engeli keeps a confident allometric development development, and you may a strong relationship anywhere between weight and you will total length.

R2 – dedication coefficient, roentgen – relationship coefficient, Letter – level of fish sampled.

R2 – dedication coefficient, r – correlation coefficient, Letter – quantity of fish tested.
According to sampling seasons, an average b property value L. macrolepis (men and women) is actually dos.78 from inside the inactive 12 months and you may 2.twenty-eight inside wet-season (Shape 4a). The brand new b property value Yards. engeli is actually step 3.42 during the deceased 12 months and you may 2.forty eight within the wet-season (Shape 4b). This type of investigation mean that the newest b worthy of is gloomier for the wet season both for variety. The spread out plots off predicted fundamental lbs getting particular observed size, once the calculated regarding chemical regarding size–weight regression, is actually showed within the Shape 2c and you can 2d and you will Figure 3c and you will d. The fresh new regression models inform you an improvement amongst the noticed and forecast development models in species.

R2 – determination coefficient, roentgen – correlation coefficient, N – level of seafood sampled.
Position facts. The results revealed that the male L. macrolepis had a great Fulton’s condition (K) factor of just one.19, and you can relative pounds standing grounds (Wr) out of ; as the female had an effective Fulton’s status foundation of just one.19 Age Gap Sites singles dating website, and you may cousin lbs position grounds of . Additionally, men Yards. engeli got an excellent Fulton’s status factor of just one.05, and you may relative lbs condition factor from ; while the female has actually Fulton’s status basis of just one.06, and you can cousin pounds updates foundation regarding (Desk step one). Considering sampling seasons, this new Fulton’s updates from L. macrolepis when you look at the dead 12 months are step one.22 and for the cousin pounds; in wet season they were step 1.19 and you can , correspondingly. While doing so, the K and you will Wr thinking regarding Yards. engeli for the dry season had been step 1.03 and you will , respectively; for the wet season these were 1.09 and , respectively (Table 2). The content of the weather condition was seen visually. The changing times are mostly rainy while in the sampling regarding the wet season, thin turbidity is higher with this year.
