Abstract:
Abstract Increased resistance of pathogenic bacteria due to the use of antibiotics has become a major concern in the aquaculture industry. Environmentally friendly products are urgently needed to replace antibiotics for the treatments of fish diseases. This study aims to determine the activity of extract of Jeringau (Acorus calamus) as an antibacterial towards Aeromonas hydrophila, Pseudomonas aeruginosa and Vibrio alginolyticus. The A. calamus extract was obtained by maceration using ethanol as a solvent. This extract was tested for its phytochemical content and its antibacterial activity was tested using the agar diffusion method. The treatments used were concentrations of A. calamus extract 200, 300, 400, 500 and 600 mg mL-1. Phytochemical test results of A. calamus extract produced alkaloids, phenolic compounds, saponins, terpenoids and flavonoids. The results of the inhibition test showed that A. calamus extract with a concentration of 200 was able to inhibit the growth of Aeromonas hydrophila bacteria by 13.9 mm, 300 (14.4 mm), 400 (14.8 mm), 500 (16.2 mm), 600 (16.5 mm). On Pseudomonas aeruginosa, the concentrations were 200 (13.9 mm), 300 (14.5 mm), 400 (15.2 mm), 500 (15.5 mm), 600 (16.2 mm). On Vibrio alginolyticus, the concentrations were 200 (15.5 mm), 300 (15.7 mm), 400 (16.4 mm), 500 (18.7 mm), 600 (19 mm). In conclusion, A. calamus extract can be used to inhibit the growth of pathogenic bacteria in fish.

Abstract:
The article presents the results of research on the toxicity determination of phytopreparations in the composition of common powdery mildew + calamus + pear Late November + bischofite; common powdery mildew + calamus + bischofite; pear Late November + bischofite, which have a universally broad spectrum of bactericidal action against Staphylococcus aureus and Escherichia coli. When studying the toxicity of phytopreparations on guppy fish, it was found that when adding the infusion to water in the composition of common powdery mildew + calamus + pear Late November + bischofite with exposures of 30 minutes and 60 minutes, all fish in a group of 10 had an adverse reaction. With an exposure of 24 hours, mortality reached up to 20 %. The highest fish mortality occurred at 24 hours in the composition of common powdery mildew + calamus + bischofite, with a mortality rate of 40 %. The composition of pear in late November + bischofite showed no signs of toxicity; all fish in the group remained alive during the study. Visually, motor activity, behavioral reactions, changes in skin pigmentation, and breathing intensity were average. The survey of skin-irritating effects of phytopreparations was conducted on laboratory animals in 20 individuals – Alaska breed rabbits. It was established that during the observation period, the following signs were absent: the presence of temperature; moderately expressed, expressed, and sharply expressed erythema; pain (with a slight thickening of the skin followed by flaking); pain, swelling, and ulcers (thickening of the skin in the application area on the rabbit). After applying phytopreparations to the skin of rabbits with exposures of 1 hour, 24 hours, 48 hours, and 72 hours, no behavioral and visual changes of an inflammatory nature were detected. When applied to the animal's skin, the investigated plant-based disinfectants do not cause irritating, necrotic, or absorptive effects. Throughout the observation period, no visible changes were observed in laboratory animals' experimental and control groups. The conducted research indicates the possibility of safe application of these plant-based disinfectants in the presence of animals.

Abstract:
Ages of whitebone porgy (Calamus leucosteus) (n = 559) from southeastern U. S. commercial and recreational fisheries from 1975 – 2017 were determined using sectioned otoliths. Opaque zones were annular, forming April – July (peaking in June). Ages ranged from 2 – 19 years, and the largest fish measured 513 mm TL (total length, mm). Body size relationships were: TL = 1.09 FL + 16.07 (n = 469, r2 = 0.97), FL = 0.89 TL – 6.39 (n= 469, r2 = 0.97), W = 2.8 x 10-5 TL2.91 (n = 462), and W = 6.8 x 10-5 FL2.82 (n = 417) where W is total weight (grams, g) and FL is fork length (mm). The von Bertalanffy growth equations were Lt = 365 (1 - e-0.35 (t + 1.37)) (n = 559) for all areas combined, Lt = 365 (1 - e-0.55(t + 0.00)) (n = 185) for fish from North Carolina through Cape Canaveral, Florida, and Lt = 368 (1 - e-0.25 (t + 2.51)) (n = 374) for fish from southeast Florida. Mean size-at-age was significantly different between regions for ages 4 – 9, (92% of total samples). Point estimates of natural mortality were M = 0.22 and M = 0.30 for northern- and southern-region fish, respectively, while age-specific estimates of M were 0.85 – 0.55 y-1 for ages 2– 19 for the northern region and 0.41 – 0.26 (ages 2-14) for southern region fish. This study presents updated life history parameters for whitebone porgy from the Atlantic waters off the southeastern United States.

Abstract:
Ages of jolthead porgy (Calamus bajonado Schneider 1801) (n = 635) from Florida commercial and recreational fisheries from 2008–2016 were determined using sectioned sagittal otoliths. We determined, using edge-type analysis, that opaque zones were annular, forming March–June (peaking in April). Jolthead porgy ranged from 1–13 years, and the largest fish measured 680 mm TL (total length, mm). Body size relationships for jolthead porgy were TL = 1.09FL + 20.44 (n = 622, r2 = 0.99), FL = 0.90 TL –14.26 (n = 622, r2 = 0.99), and W = 1.1 × 10−5 TL3.06 (n = 577), where W is total weight (grams, g) and FL is fork length (mm). The von Bertalanffy growth equation for jolthead porgy was Lt = 737(1 − e−0.14(t+2.02)) (n = 635). Point estimate of natural mortality was M = 0.32, while age-specific estimates of M ranged from 0.58–0.17 y−1 for ages 1–13. Catch curve analysis estimated the instantaneous rate of total mortality Z = 0.70, while instantaneous rate of fishing mortality F was 0.38. Macroscopic staging of female gonads indicated the presence of hydrated oocytes from December–March, and GSI data indicates that peak spawning in females occurs during March. This study presents the first published findings of life history parameters for jolthead porgy from the Atlantic waters off the southeastern United States.

Abstract:
The monogenean Haliotrematoides mediohamides Kritsky & Mendoza-Franco, 2009 (Monogenea: Dactylogyridae) is redescribed based on examination of the type specimen (paratypes) and newly collected specimens parasitizing the gills of the Pacific porgy, Calamus brachysomus (Lockington, 1880) (Perciformes: Sparidae) (type host), a neritic fish captured off the coastal zone of Puerto Pizarro, Tumbes, Peru. Even though this monogenean was described 12 years ago, that description did not report some of the unique morphological features of H. mediohamides and neither did it offer a whole-mount drawing of this species. The most important characteristics of H. mediohamides are: 1) a male copulatory organ with hook-shaped distal end, 2) a non-coiled vaginal duct, 3) numerous secretory gland-cells associated with the peduncle, 4) a chandelier-shaped extrinsic adductor muscles articulated with superficial roots of the anchors, 5) a single tadpole-shaped prostatic reservoir, and 6) a vas deferens anteriorly convoluted. In addition, the first whole-mount drawing of H. mediohamides, as well as morphometric data are provided. Haliotrematoides mediohamides represents the first record of Haliotrematoides in South America. Haliotrematoides mediohamides is the third dactylogyrid species recorded to infect C. brachysomus in Peru.

Abstract:
In recent years considerable media attention has been focussed on the “Mimic Octopus”, an Indo-West Pacific long-armed species which impersonates numerous poisonous or dangerous animals. This distinctive octopus is here described. A combination of unique morphological characters justify this octopus being placed in a new genus. These characters include: absence of a calamus on the copulatory organ, absence of enlarged suckers in either sex; long narrow arms capable of arm autotomy at a set level near the base; and distinctive base components of colour patterns including a white teardrop ring on the mid-dorsal mantle and a distinct white “U” patch on the posterio-dorsal mantle. Thaumoctopus mimicus n. gen. et sp. is reported primarily from the Indo-Malayan Archipelago from New Caledonia to Indonesia, Malaysia and the Philippines. Photographic records from the Red Sea extend the distribution to the western Indian Ocean. This octopus occurs in shallow waters (0.5–37 m) on soft sediment substrates where it is day-active, foraging for small fish and crustaceans. It is delineated from other long-armed genera and species complexes within the genus Octopus. Other undescribed species are flagged as potential members of the new genus Thaumoctopus. Links between habitat preference and the origins of this unique mimicry are explored.

Abstract:
Sportfishing is an activity of increasing popularity that involves a large number of users and high levels of fishing effort. In Yucatan, most of the target species in sport fishing are the same as those of commercial fisheries. However, there is no record of fishing effort or catch volumes. Thus the impact of sport fishing on these populations is unknown. This study analyzes the catches made by users of sport fisheries of nine species (Epinephelus morio, Haemulon plumieri, Seriola dumerili, Lutjanus synagris, Ocyurus chrysurus, Calamus bajonado, Sphyraena barracuda, S. guachancho and Mycteroperca bonaci) through length-based indicators. Samples of species’ sizes were obtained from the catches made during 10 fishing tournaments held in Yucatan's three-port towns (Sisal, Yucalpeten, and Telchac) between 2015 and 2016. The catch variables that were evaluated included: the number of mature individuals Pmat, optimal length Popt, and the number of mega-spawners Pmega. Length measures were derived from 1,252 individuals. Only H. plumieri, L. synagris, and S. guachancho exhibited sustainable indicator values, while E. morio and C. bajonado demonstrated extremely low values. In most species, sport fishing affects a high proportion of juveniles. The results suggest that sportfishing contributes to the fishing pressure of a species and commercial fishing, due to the capture of juveniles of economically important fish. It is essential to establish a systematic monitoring method of such activities and increase the priority level of the evaluation and management of this fishery.

Abstract:
Shrimp feed formulations have moved towards less fish meal and more of the readily available and cheaper plant proteins. To counteract the lower attractiveness and palatability of plant proteins, feeds are supplemented with ingredients known to have chemoattractive properties that will increase feed intake. This study investigated the putative chemoattractive effect of Calanus finmarchicus hydrolysate, when used as a dietary supplement in shrimp feeds. C. finmarchicus is a zooplankton species native to the northern Atlantic Ocean and is a novel and sustainable raw material for shrimp feed products. Diet attractiveness was evaluated in a 24-day feeding trial with whiteleg shrimp (Litopenaeus vannamei) by measuring the intake of 12 diets with various levels of fish meal, calanus hydrolysate, and krill (Euphausia superba) meal. Higher inclusion rates of both ingredients resulted in increased feed intakes, and supplementing the high fish meal diet with calanus hydrolysate gave a statistically significant higher feed intake. Low molecular weight peptides, chemoattractive amino acids, and the water-soluble nature of the hydrolysate could explain the chemoattractive properties observed in the study.

Abstract:
Abstract Copepods from the genus Calanus are crucial prey for fish, seabirds and mammals in the Nordic and Barents Sea ecosystems. The objective of this study is to determine the contribution of Calanus species to the mesozooplankton biomass in the Barents Sea. We analyse an extensive dataset of Calanus finmarchicus, Calanus glacialis, and Calanus hyperboreus, collected at various research surveys over a 30-year period. Our results show that the Calanus species are a main driver of variation in the mesozooplankton biomass in the Barents Sea, and constitutes around 80% of the total. The proportion of Calanus decreases at low zooplankton biomass, possibly due to a combination of advective processes (low C. finmarchicus in winter) and size selective foraging. Though the Calanus species co-occur in most regions, C. glacialis dominates in the Arctic water masses, while C. finmarchicus dominates in Atlantic waters. The larger C. hyperboreus has considerably lower biomass in the Barents Sea than the other Calanus species. Stages CIV and CV have the largest contribution to Calanus species biomass, whereas stages CI-CIII have an overall low impact on the biomass. In the western area of the Barents Sea, we observe indications of an ongoing borealization of the zooplankton community, with a decreasing proportion of the Arctic C. glacialis over the past 20 years. Atlantic C. finmarchicus have increased during the same period.

Abstract:
Abstract Predator avoidance adaptations other than escape jumps and DVM are described. Eyes of many fish search upward, their mouths opening toward prey above. A role is suggested for the red caps on the posterior oil sac tips of Calanus and its relatives: reducing the hunting success of such fish. Evolution of such red caps seems an instance of the so-called “Red Queen” process. Some nearly transparent grazing copepods with no DVM eat little during daylight, avoiding dark-pigmented guts. Other grazers eat less at night when potential prey, usually dinoflagellates, luminesce if disturbed. Best not to be located in a tiny center of flashing blue-green lights. Another turn of the Red Queen “rachet” could be the recently discovered responses of diatoms to some copepod secretions. One response is cell division without chain formation. One of two separate cells might avoid capture, a lesser stock loss than copepod meals of two or many cells. Bioluminescent blasts along the predator escape paths of Augaptilid copepods suggest they blind or distract eyed predators at night. The molecular biology of the luminescent systems of Metridia has been studied extensively, thanks to applications for tracing specific metabolic reactions.

Abstract:
Abstract Early near-surface zooplankton sampling revealed more of many species being caught at night than in daylight. Hypotheses abounded, several still current. For many species the answer is daily (“diel”) vertical migration (DVM): down to darker waters during daylight, up to better feeding at night. Daytime abundance increases in deeper, darker strata. A 1930s study by the late G. L. Clarke demonstrated DVM by Calanus finmarchicus. Algae and animals eating algae (protozoa to copepods) are more abundant in the surface; migrators must go there to feed. However, visual predators (e.g., fish) are more dangerous there in daytime. Avoiding visual predators is obviously advantageous, but selection of DVM for that advantage is difficult to prove. Chapter 8 details five studies demonstrating that predation-avoidance is usually the main gain. Bios cover the careers of Steven Bollens and Mark Ohman.
