macrolepis had negative allometric growth habits. Yet not, this new b property value the fresh new women is less than compared to the male. This new b value of the male Meters. engeli demonstrated a confident allometric growth trend. Centered on these types of development pattern research, the research indicated that Yards. engeli expands better than L. macrolepis, and so indicating you to definitely Meters. engeli is much more versatile on environment condition from Lambada Lhok waters. Furthermore, the field observance on the catch structure of your own anglers exhibited you to Yards. engeli has also been prevalent. This new Fulton’s status grounds displayed hook difference in K value amongst the male and female both for kinds, the spot where the K worthy of are more than step one. According to Morton and you can Routledge thirty-six , a seafood inhabitants is in good shape when the K value is higher than 1. The analysis showed that the latest K value of L. macrolepis varied from one.16 to at least one.twenty-two, and you will 1.03 to just one.09 to have Yards. engeli; thus, one another populations have been in great condition, into the dead and you can wet season, respectively. At exactly the same time, the new relative weight condition foundation from both species is practically 100, indicating a balance ranging from prey and you will predator 20 . These types of performance show that this type of seas offer an adequate dining supply for those types. The newest relative lbs standing factor including corresponds to fish illnesses, stock prices, and you can administration accounts 23,thirty-five,36,38,39 . For this reason, the fresh new Lambada Lhok oceans promote adequate eating provide to have mullets.
Dining table 2. The fresh new b really worth, coefficient off relationship and you may dedication, and you may updates activities out of Liza macrolepis dan Moolgarda engeli sampled regarding pling season
The outcome also demonstrated variations in increases activities in the dry and you may damp season, hence this new fish expanded most readily useful when you look at the inactive season. New possible cause is the fact that the seas are obvious and good restrict rate away from sunrays permeates on oceans, triggering the organization out-of phytoplankton and you will algae. Algae was a first food towards the mullets 40–43 . In comparison, turbidity and currents was in fact highest in the wet-season 44 , and you may and thus think in order to inhibit the organization off phytoplankton and you can algae as vital food for mullets 42,45 . A similar experience are advertised of the Chu et al. 29 , who discover a terrible increases pattern when you look at the L. macrolepis for the Taiwan while in the cold temperatures, and an isometric growth pattern in the summer and spring season. Moreover, Sandhya and you can Shameem 31 noticed a terrible development trend inside L. macrolepis within the contaminated waters, compared with an isometric growth trend when you look at the unpolluted oceans. Yet not, a face-to-face trying to find is reported in the five species of seafood (Barbus intermedius, Clarias gariepinus, Labeo cylindricus, Oreochromis niloticus baringoensis and you can Protopterus aethiopicu) regarding the Lake Baringo, Kenya 46 in which this type of types is actually expanding really through the wet-season 46 . Ergo, they determined that 12 months affected notably towards the LWRs, but failed to change the standing grounds regarding fish 46 . A terrible gains pattern has also been claimed within the three types of mullets (Parachelon grandisquamis, Neochelon falcipinnis and Mugil cephalus) from the Sombreior Lake, Niger Delta, Nigeria 47 . Considering Blackwell mais aussi al. 20 new Wr is right so you’re able to estimate seafood health issues, stock, and you can government degrees of fisheries info.
According Muchlisin et al. twenty two , and suffering from the environmental items, the organization trend off seafood is additionally influenced by fish conclusion; for example, the newest fish that have been productive swimmer got less b value than those that have been inactive swimmers forty eight–fifty .
An average relationship coefficients out of L. macrolepis were 0.93 and 0.89 in women and you can boys, respectively, whereas Yards. engeli got a correlation coefficient out-of 0.89 for men and 0.93 for females. Overall, the new correlation coefficients out-of L. macrolepis and you will Yards. engeli include equivalent (more than 75%), showing a strong correlation ranging from full length and the entire body lbs. The commitment coefficients off L. macrolepis was in fact 0.85 and 0.65 into the male and female seafood, respectively, meaning that as much as 65%–85% out of full alternatives would be explained because of the design, when you find yourself Yards. engeli had a worth of 0.ninety and you can 0.94 for men and you may women, correspondingly, indicating you to best Adventist dating site 90%–94% out-of variants will be told me by model.
