macrolepis had bad allometric gains habits. Yet not, the brand new b value of the latest females is below compared to a man. This new b property value the male Meters. engeli exhibited a positive allometric gains development. Considering this type of increases development data, the research indicated that Meters. engeli expands much better than L. macrolepis, and therefore exhibiting one to Yards. engeli is more versatile with the ecological position from Lambada Lhok seas. Also, industry observation into catch constitution of anglers presented one Meters. engeli was also common. New Fulton’s reputation grounds displayed hook difference between K well worth between your men and women for types, the spot where the K worth are more than step 1. Considering Morton and Routledge 36 , a fish population is within good condition when the K worth is higher than 1. The research indicated that the new K property value L. macrolepis ranged from a single.16 to 1.twenty-two, and you will step one.03 to one.09 to own M. engeli; therefore, one another populations are in good condition, for the dry and you will wet-season, respectively. At the same time, the newest relative pounds position grounds away from each other varieties is virtually a hundred, exhibiting an equilibrium ranging from target and predator 20 . This type of overall performance demonstrate that these types of oceans bring an adequate restaurants provider for these variety. The fresh relative lbs status basis including represents seafood illnesses, inventory prices, and administration account 23,35,36,38,39 . Ergo, this new Lambada Lhok seas bring adequate food supply to own mullets.
The outcomes plus displayed differences in development activities in the lifeless and you can moist seasons, and that this new seafood expanded better from inside the dead season. The newest probable need is the fact that the seas are obvious and a limit rates from sunlight permeates on waters, creating the growth of phytoplankton and you may algae. Alga are an initial meal to your mullets 40–43 . By comparison, turbidity and you can currents was highest inside wet-season forty two , and you can thereby assume so you’re able to prevent the growth regarding phytoplankton and you will algae as essential food getting mullets 42,forty five . A similar trend try reported because of the Chu mais aussi al. 30 , which discovered an awful development development for the L. macrolepis during the Taiwan during the cold temperatures, and you can an enthusiastic isometric growth trend during the summer and you may spring. Also, Sandhya and you may Shameem 31 observed a terrible growth pattern into the L. macrolepis in contaminated waters, compared to a keen isometric progress pattern during the unpolluted oceans. However, a reverse searching for is actually said within the five species of seafood (Barbus intermedius, Clarias gariepinus, Labeo cylindricus, Oreochromis niloticus baringoensis and you will Protopterus aethiopicu) regarding the Lake Baringo, Kenya 46 in which these types of variety try expanding well throughout the wet-season 46 . For this reason, it determined that 12 months impacted notably on the LWRs, but did not change the condition grounds out-of fish 46 . A negative increases pattern has also been said for the around three types of mullets (Parachelon grandisquamis, Neochelon falcipinnis and you can Mugil cephalus) on Sombreior Lake, Niger Delta, Nigeria 47 . According to Blackwell ainsi que al. 20 the new Wr is good to help you imagine fish health conditions, inventory, and you can management degrees of fisheries resources.
In respect Muchlisin mais aussi al. 22 , as well as struggling with environmentally friendly activities, the organization pattern off fish is even dependent on fish conclusion; instance, the newest seafood that were active swimmer had a reduced b worth than those which were couch potato swimmers 48–fifty .
Table dos. The brand new b value, coefficient from relationship and you will determination, and you may reputation items away from Liza macrolepis dan Moolgarda engeli tested out of pling season
An average relationship coefficients out-of L. macrolepis was 0.93 and you may 0.89 in females and you may guys, respectively, whereas M. engeli got a relationship coefficient of 0.89 for males and you can 0.93 for ladies. http://www.datingranking.net/tr/muslima-inceleme Overall, brand new relationship coefficients off L. macrolepis and you may Yards. engeli include similar (significantly more than 75%), exhibiting a powerful relationship between complete duration and body lbs. The new commitment coefficients off L. macrolepis was basically 0.85 and you will 0.65 to your female and male fish, correspondingly, meaning that approximately 65%–85% out-of full variations would be explained by model, if you find yourself M. engeli had a worth of 0.ninety and you can 0.94 for males and you may female, correspondingly, exhibiting that 90%–94% from variations should be explained from the design.
