The knowledge were presented while the dining tables and you can figures, and then the investigation was basically assessed descriptively because of assessment that have related reports, ideas, and you may occupation observations.

Length-pounds dating

The field observance of your catch structure indicated that Liza macrolepis and you can Moolgarda engeli were widespread. All in all, 242 L. macrolepis and you can 109 Meters. engeli was indeed tested and counted regarding data. The length of male L. macrolepis ranged off 141.cuatro – 202.step 1 mm (164.8 ± mm), and varied regarding 129.2–185.cuatro mm (159.step 1 ± mm) for females. You pounds off male L. macrolepis varied away from 34.seven g so you can 89.6 g (54.step 1 ± 13.3 g inside the mediocre), and you may twenty-eight.8 g so you’re able to g (47.nine ± nine.52 grams in mediocre) in females. The size of the male Yards. engeli ranged out of 109.9–188.5 mm (161.9± mm) and you may 116.5–182.step 3 mm (154.1 ± mm) for ladies. One’s body weight of the men try thirteen.six – 108.5 gram (47.6±19.3 gram), which of the girls was fourteen.2–75.1 gram (41.cuatro ± gram). Brutal research are available because fundamental data 37 .

The outcomes of one’s LWRs investigation on the L. macrolepis indicated that the male fish had a-b worth of 2.49 with a relationship coefficient from 0.93, as well as the women fish got a b property value step one.81 and you can a relationship coefficient out-of 0.82 (Shape 2a and you will 2b). For this reason, a man and you can female L. macrolepis presented negative gains activities, and you can an average relationship anywhere between body weight and you will full period of the brand new fish. The outcomes regarding LWRs research out-of male Meters. engeli indicated that the common b value was step 3.twenty two with a great coefficient correlation off 0.89. The feminine M. engeli got the common b value of 3.41 that have good coefficient relationship out-of 0.93 (Shape 3a and you will 3b). Such analysis mean that the male and ladies Meters. engeli have an optimistic allometric increases development, and you can a strong correlation between pounds and complete size.

The exact distance-weight relationship away from Liza macrolepis centered on linear allometric model (a) men, (b) female; Comparison away from observed and you can predicted growth for men (c), and people (d) away from Liza macrolepis. R2 – commitment coefficient, roentgen – relationship coefficient, N – quantity of seafood tested.

Shape step 3.

The distance-pounds matchmaking out of Moolgarda engeli based on linear allometric model (a) male, (b) female; Evaluation out-of observed and forecast increases to possess men (c), and people (d) off Moolgarda engeli. R2 – dedication coefficient, r – relationship coefficient, Letter – quantity of seafood tested.

According to testing year, the common b property value L. macrolepis (female and male) is actually dos.78 in the deceased 12 months and you may 2.twenty-eight for the wet-season (Shape 4a). This new b property value Meters. engeli is step three.42 in dead 12 months and you can 2.48 when you look at the wet season (Figure 4b). These data imply that new b well worth is lower in wet season both for types. New spread out plots from forecast practical lbs to own particular observed length, once the computed regarding compound out of length–pounds regression, are showed for the Figure 2c and you may 2d and you can Shape 3c and d. The latest regression designs reveal a change involving the seen and you can predict development models in variety.

Shape cuatro.

The distance-pounds relationship off Liza macrolepis (a) through the inactive seasons (b) during wet-season and you may Moolgarda engeli (c) during the lifeless 12 months (d) during the wet-season. R2 – dedication coefficient, r – relationship coefficient, N – number of fish sampled.

Standing items. The results revealed that a man L. macrolepis had a great Fulton’s reputation (K) basis of 1.19, and you will relative lbs position basis (Wr) out-of ; as female got good Fulton’s condition basis of 1.19, and you can relative lbs reputation basis out of . Concurrently, men M. engeli got good Fulton’s reputation basis of 1.05, and you may cousin weight standing basis of ; while the new people provides Fulton’s standing factor of 1.06, and cousin lbs reputation basis off (Dining table step 1). Predicated on testing season, the new Fulton’s condition out-of L. macrolepis inside the deceased seasons is 1.twenty two and also for the relative pounds; within the wet season these were step one.19 and you will , respectively. At the same time, new K and Wr beliefs off Meters. engeli in deceased year was basically 1.03 and you can , respectively; within the wet-season these were 1.09 and you may , correspondingly (Desk 2). The data of your weather had been observed visually. The occasions are typically wet while in the testing on the wet-season, and so the turbidity was high with this seasons dating services Asian Sites.
